(1) Using the micrometer conventionally, bring the measuring faces up snug to the piece being measured, and then load the micrometer by continuing to rotate the red graduated thimble through ten of its divisions. (There are four equally spaced red reading lines on the.0001 reading sleeve and four sets of numbered red graduations on the.0001 thimble reading zero to nine. This allows you to read the.0001 graduations no matter what position the micrometer is held.) (2) Hold this loaded position and now observe the black.001 graduations on the inner thimble in relation to the reading line on the sleeve. Slowly let the red graduated thimble return until the first black thimble graduation aligns with the black reading line on the sleeve. Now hold this position with the black graduations aligned. C B A. Inner Sleeve B. Inner (Black) Thimble C. Black.001 reading line D. Outer sleeve with four equally spaced red.0001 reading lines E. Red Graduated Thimble (3) At this point the black graduations will be your.001 reading and you can then take the.0001 reading directly from the red graduated thimble as it lines up to the red reading lines at any one of the four positions, and add it to the.001 reading. CAUTION: Do not force the red graduated thimble if you feel it hit the stop. Also, do not at any time let the red graduated thimble snap back from its loaded position. Damage could occur due to either circumstance. E NOTE: Constant pressure mechanism available on micrometers in larger sizes on special order.

37 OUTSIDE MICROMETERS SPECIAL FUNCTION Special Function Micrometers Throughout its history, The L.S. Starrett Company has manufactured a multitude of special hand tools and gages for thousands of customers in many different industries. Illustrated on these first two pages are typical examples of Starrett special toolmaking. The following pages show special function tools that we make as regular items because they are commonly used in industry. Special toolmaking activities are coordinated under the direction of special order sales engineers who oversee each order from the time it is entered until shipment is made. Complete manufacturing facilities and engineering counsel are available. Customers are invited to submit drawings and specifications for prompt quotation. Please direct these to the attention of: The L.S. Starrett Company Special Order Department 121 Crescent Street Athol, MA Starrett can manufacture extra large micrometers, like this special No. 724 Micrometer of tubing type construction, range ( mm), with interchangeable anvils. Special Tools Ultralight C Frame Gages Special No. 436 Micrometer with dial indicator head. Range 3-4 (75-100mm). Other ranges also available. Rigid honeycomb aluminum diameter gage weighs five times less than solid frame gages. Unit shown has interchangeable anvils for range. (Also available with fixed anvils.) The gage is used as a dial indicator snap gage set to produce nominal dimension, or as an indicating micrometer. The micrometer head with.0001 graduations and the.0005 dial indicator insure quick, accurate readings. Ultralights are available from ( mm) I.D. or O.D. and can be designed for up to 72 (1800mm) throat depth for thickness measurement. 37

38 OUTSIDE MICROMETERS SPECIAL FUNCTION Micrometer Head Speeds Gaging A specially shaped micrometer frame, to access an I.D. on an odd shaped part, is equipped with the Starrett No. 204 Quick-Adjusting Micrometer Head. This tool greatly increases the speed with which measurements can be taken. Pressing a button on the thimble allows the spindle to slide along its axis to any position within its range. Releasing the button re-engages the spindle threads, and thimble rotation is then used for final size adjustment. The No. 204 Micrometer Head can be mounted on frames designed to suit your particular applications. Quotations and a concept print for your application can be obtained by submitting a product drawing with the thickness dimension(s) circled to: The L.S. Starrett Co., Special Gage Division, 121 Crescent Street, Athol, MA Special No. 725 Deep Throat Tubular Micrometer With sliding, interchangeable anvils and locking lever, 7-1/2 (185mm) depth, 0-6 (0-150mm) range. 38

39 OUTSIDE MICROMETERS SPECIAL FUNCTION Mul-T-Anvil Micrometers No. 220 Series 0-2 No. 220M Series 0-50mm This tool was a new development in micrometer design and patent is held by Starrett. This micrometer will handle a wide variety of measurements impossible to obtain with regular micrometers, such as measuring the wall thickness of tubing, cylindrical walls from a hole or slot to an edge, many hard-toreach locations, and the thickness of screw heads, shoulder lengths, etc. A most interesting feature of this tool is that additional anvils of various shapes can be made up, and many of these anvils do not have to be hardened for that special job. This micrometer can be furnished with.0001 graduations, but we recommend.001 or 0.01mm for easier and more accurate readings. The Starrett Company, with our years of experience, recommends this because the anvils on this type of tool are not backed up by a frame as in a regular micrometer and could bend slightly. Ease-of-Handling Features Balanced frame and thimble design insure easy handling, better readability Ring-type knurled lock nut for quick and sure locking A choice of smooth friction thimble for uniform pressure or the combination ratchet and speeder for uniform pressure and quicker adjustment Interchangeable anvils are rigidly held in the vise type frame and quickly interchanged by a single lock screw adjustment Two hardened anvils furnished round anvil approximately.120 diameter (3mm) and flat anvil approximately.125 (3mm) and.060 (1.5mm) thick V Anvil for measuring thickness of screw heads and shoulder lengths available separately Accommodates special anvils up to 5/16 (8mm) thick Can be used as a height gage by removing the vise jaw Readability Features Starrett satin chrome finish no glare resists rust Advanced sleeve design with staggered lines and distinct figures for precise and easy readability Quick-reading figures every thousandth numbered on inch tools With Round and Flat Anvils and Carbide Faced Spindle Ratchet Stop, Lock Nut Friction Thimble, Lock Nut Range Graduation Catalog No. EDP No. Catalog No. EDP No XRL XFL mm 0.01mm 220MXRL With Round and Flat Anvils, Carbide Faced Spindle and With No. 234B-1 or No. 234MB-25mm End Measuring Rod or Standard XRL XFL mm 0.01mm 220MXRL Accuracy and Long-Life Features Rigid one-piece frame of drop forged steel Extremely hard and stable one-piece spindle (the heart of our accuracy) Micro-lapped measuring faces Quick and easy adjustment Starrett workmanship Tool is accurate to ±.0002 or ± 0.004mm V-Anvil only: Order No. PT13017, EDP and 25mm models sent in fitted case.

78 MICROMETER HEADS Direct-Reading, Large Micrometer Heads These large micrometer heads are designed for use with electronic equipment requiring ultra-fine adjustment for machine tools, fixtures, special gages and tools, special mountings, or wherever micrometer accuracy in setting and adjustment is required. The micrometer heads with 2-1/16 (52mm) thimble diameter have widely spaced.0001 or 0.002mm graduations. The micrometer heads with 4-1/16 (103mm) thimble diameter have graduations up to or 0.001mm. Another highly useful feature is the spindle adjustment, which permits adjusting the spindle length approximately ±1/16 (1.5mm). If the spindle is to be located against a definite stop and a different zero position is required, first loosen the cap screw in the end of the thimble, position the spindle to the desired location, then holding the spindle in position, rotate the thimble to zero and retighten the cap screw. In achieving this adjustable feature, we have still retained our positive taper-lock large thimble bearing.

82 BENCH MICROMETERS Direct-Reading Bench Micrometers No No. 673M 0-50mm 0-2 / 0-50mm Ranges The Starrett No. 673 bench micrometer is a high precision instrument, ideal for bench use either in a shop environment or inspection laboratory. It can be used as a comparator measuring to fifty-millionths of an inch ( ) or two-thousandths of a mm (0.002mm) or for direct measuring to.0001 or 0.002mm. Work lengths up to 2 or 50mm can be measured. The base is a heavy, rigid casting, incorporating at the left end a movable anvil which actuates a linear, friction-free motion transfer mechanism between the anvil and the indicator. This assures high accuracy The large thimble diameter, approximately 3 (77mm), makes possible widely spaced graduations that are easy to read without a vernier scale reference Advanced, staggered design and quick reading graduations in combination with Starrett no-glare satin chrome finish on both thimble and sleeve also contribute to easier, faster readings The head is furnished with a speeder and has a special ring-type lock nut which firmly holds the spindle at any setting without distortion Another useful feature is the adjustable work table centered beneath the anvil and spindle. Work can be accurately aligned between the anvil and spindle by adjusting the table to the proper height and locking it in position The spindle and anvil are carbide faced for long life This bench micrometer can also be used with the No. 718 Analog Amplifier or the No. 776 Electronic Gage Amplifier by using the No. 673A Adaptor for the No Cartridge-Type Electronic Gaging Head to read to ten-millionths of an inch ( ) or mm NOTE: Anvil Pressure Adjustment 8 oz. to 3 lbs. (0.23 to 1.36kg) Furnished in a case. Packed one in a box. Starrett No. 673XZ Bench Micrometer (Inch model). Shown here is the No. 673 with the Starrett No. 718 Amplifier. How to Use for Direct Measure and as a Comparator For direct measuring, the micrometer head is set to zero and the dial indicator is set to zero by the bezel adjustment. Any workpiece within the 2 (50mm) range can then be measured by the micrometer head in ten-thousandths of an inch (.0001 or 0.002mm). The indicator must read zero for each measurement. If used as a comparator, first set the head and the indicator to zero as previously explained. Then adjust the micrometer head to the desired dimension to be checked. After retracting the anvil, work is placed on the table between anvil and spindle and the anvil is then released so anvil and spindle contact the work. Plus or minus deviation from the nominal work size is then read from the dial indicator in fifty-millionths of an inch ( ) or 0.002mm.

84 END MEASURING RODS AND INSIDE MICROMETERS The following pages show our varied line of precision end measuring rods and inside micrometers. The variations are fixed-range or adjustable-range micrometers and solid or tubular measuring rods. Unless otherwise noted under the individual tools, all have these features: Balanced design for better feel and accurate measurement All contact points are hardened and ground for better accuracy and long life Satin chrome finish on all micrometer heads and reading surfaces that resist rust and also make for easy reading by providing a no-glare background for the sharp lines and figures Hardened and stabilized spindle for accuracy and long life Advanced sleeve design with staggered lines and distinct figures for precise and easy readability Quick and easy adjustment Starrett workmanship Inside Micrometers Nos. 121, 124, 823 and 824 by design have a firmer rotation than regular micrometers. This is to limit the tendency of the micrometer head to rotate when withdrawn from the workpiece. Measuring Tips for Inside Measurements Whether to use a two-point or threepoint contact measuring tool is usually a matter of preference, but there are some differences. A two-point contact rod-type inside micrometer shown in this section is usually lighter, easier to handle, and more versatile over long ranges from approximately ( mm). Any two-point contact micrometer, regardless of range, can probe a hole better to find the geometry of that hole than a three-point contact. Most three-point contact tools have setting rings to insure accuracy. If you desire very close tolerance work with two-point contact inside micrometers, it is recommended that they be set to a ring gage or to an outside micrometer. A three-point contact micrometer shown in the Bore Gages section has an advantage in that it can be seated in position more quickly than a two-point contact tool. Usually these tools can also be read to a finer accuracy. The three-point tool will tell the maximum true diameter that can enter the hole a little faster than a two-point contact tool. Micrometer heads used in these tools are accurate to ±.0001 or 0.002mm, but overall accuracy on tools that add rods is dependent on good practice and technique. To insure accuracy, these practices should be followed: Always make sure that there are no specks of dirt between the clamping surfaces of the rods and micrometer heads Tighten all rods uniformly, not too tight, not too loose, but a fairly firm assembly Assemble long sections vertically or, with support, horizontally Because temperature can affect long rods used in these tools, they should be assembled in the same environment in which they will be used (For additional information, refer to the Bore Gage Section) 83

87 INSIDE MICROMETERS Combination Head with Inside Micrometer No. 128 No. 128M The Starrett combination head for inside micrometers combines the precision of a dial indicator sensor and the linear accuracy of a micrometer. This combination of indicator and micrometer reduces the need for operator feel and provides faster readings with increased reliability. This head is interchangeable with the Starrett No. 128 Series end rods and extension combinations. For direct measurements, the dial indicator hand and the telltale hand must both register zero before reading the micrometer. As a comparator, the micrometer is first set to the nominal dimension and ± deviation from zero is read from the dial indicator. The gage should be rocked to obtain a minimum reading on the indicator. Out-of-roundness can also be checked any variation being shown by the indicator. For inch-reading tools, the head can be adjusted within a range of 2. It extends the overall range by an additional 5. The special No J jeweled non-shock Indicator is graduated.0005, range ±.040 and reads 0-40 on both the plus and minus dials. For millimeter-reading tools, the head can be adjusted within a range of 50mm. This extends the overall range an additional 125mm. The special No J jeweled non-shock Indicator is graduated 0.01mm, range ±1mm and reads 0-100mm on both the plus and minus dials. The 10 (250mm) master should be used vertically with the shoulder on the indicator end of the head, seated squarely, as shown in photo. Combination Head in master.
