AppLIcations A286 Fasteners The new and improved Jarhook is the best available tap for A286 fasteners. During extensive testing the Jarhook surpassed all of the competition in tool life and tapping speed. The data speaks for itself, in a controlled test the 0-2 Jarhook achieved an average tool life of 200 holes at a speed of 000 RPM in A286 6 point nuts. This outperformed the competition at this speed by over 0%. Davenport taps Jarvis offers high performance nib taps for tapping on Davenport machines. These taps are available as nibs alone or as a welded assembly of the nib and the shank. The nib tap can be custom made to accommodate any thread length necessary for the application. Jarvis has extensive experience making short thread length spiral pointed nib taps along with long chamfer straight fluted nib taps. Collars Jarvis has extensive experience tapping collars in a variety of materials ranging from Aluminum to Titanium 6Al 4V. This experience has assisted in the development of the optimum cutting geometries for these material specific applications.

Locking Threads Locking threads are common on a number of aerospace applications. Unfortunately most of the tap manufacturers making these locking thread form taps only offer a general purpose tap. Jarvis offers material specific Jarlock taps for the aerospace market. Some of the material we work with are Inconel 78, Waspaloy, Titanium 6AL 4V, etc. We guarentee that these taps will work with Spiralok gages. Multilead taps Jarvis offers both multilead cut and form taps for the aerospace market. Some multilead applications we are familier with are Inconel Inserts and A286 panel fasteners. Our material specific multilead taps will outperform the competition every day of the week. jet engine housing Jarvis excels in tapping 78 Inconel in any condition, one example that we have shown exceptional tool life in tapping engine components made from Inconel 78 super alloy that has gone through the HIP process. These engines components can be found on your general commercial airline. Jarvis has tapped holes in components of the new F-5 fighter jet engine. We successfully increased the customers tool life by 00% in a proprietary super alloy.

FEATURES Maximize Speed Jarvis has the answer to maximizing tapping speed and optimizing cycle times. We offer: Chip Management + High Performance Surface Treatments + Free Cutting Geometries + Proprietary Geometry + Ground Male Center Taps for shorter tap throw Effectively controlling the direction of the chip is essential for tool and machine up-time. Whether you are tapping a standard length fastener or a long-barreled fastener, Jarvis has designs to insure that the chips are released by the taps and you do not experience pull back. Jarvis also has developed solutions to evacuate chips from counter bored parts. If your operators are modifying taps, contact Jarvis for factory ground solutions. Blind hole applications Jarvis offers the highest performance SPFL taps on the market. Using a wide range of spiral flute helixes and cutting geometries we can solve any blind hole problem you may come across. Special Requirements Jarvis custom manufactures taps for all special and exoctic requirements. Some of the features we offer are: + CMD + Coolant Through + Left Hand + Nib Taps + Radius Crest + Special Thread Forms + Tapered Threads

UNJ vs. UN THreads The UNJ thread standard (ASME B.5) defines a system of threads for highly stressed applications requiring high fatigue strength. It was derived from a military specification (MIL-S-8879) originally published in December 965. MIL-S-8879 was primarily thought of an used for aerospace fastener and threaded component applications. Due to the increase in both its use and types of applications, the American Society of Mechanical Engineers developed and published ASME B.5 in 995. Form. UNJ screw threads are the same form as Unified Screw Threads to ASME/ANSI B. except: External threads: the root has a maximum and minimum prescribed continuous radius, and is not merely rounded due to tool wear. Internal threads: the minor diameter is increased to accommodate the maximum root radius of the external thread. There is no radius requirement for either the crest or the root of the internal thread. Designation. UNJ product threads are identified by the letter J in the thread symbol, and a thread class symbol including an A for external threads or a B for internal threads. Use of Unified Tooling. Many of the UNJ thread form characteristics are the same as for a UN threads. Therefore, some of the tooling used to produce one form can be used to produce the other. External UNJ threads must be produced with a prescribed root radius; therefor, standard Unified Screw Thread (UN) may not be used. Internal UNJ threads are not required to have a root radius; therefore, ground-thread taps designed to produce Unified Screw Threads of the proper class of fit may be used. The letter J need not be marked on the tap. The larger product minor diameter of the UNJ internal thread requires the use of a larger tap drill than is used when producing Unified Screw Threads.

UNDERSTANDING h-limits In addition to the nominal size and pitch of tap, there is another important dimensional factor to be considered in selecting a ground thread tap for a given job. This is the matter of the H and L pitch diameter tap limits. H means (high) above basic pitch diameter and L (low) below basic pitch diameter. Tap limits have been established to provide a choice in the selection of the tap size best suited to produce the class of thread desired. The chart below illustrates the numbering system and the.0005 diameter increment separation between successive limits. Since the starting point is basic pitch diameter, dividing the limit number by 2 establishes in thousands of an inch the amount of maximum tap pitch diameter is above the basic in the H series and the amount the minimum tap pitch diameters under basic in the L series..0050.0045.0040.005.000.0025.0020.005.000.0005 BASIC H H2 H H4 H5 H6 H7 H8 H9 H0 H4 H5 H6.0050.0045.0040.005.000.0025.0020.005.000.0005 BASIC P.D..0005 L For Taps through inc., 8 T.P.I. and finer P.D.
