3 East Julie Street 800-3-119 (Voice) 90-733-741 (Fax) TUFTHRED - FRACTIONAL & METRIC SIZES No tapping is required; just drill out the damaged threads using fractional or wire gauge drill bits. Then screw in the TufThred using a bolt and nut as an installation tool. Standard TufThreds are case hardened carbon steel. They are stronger and more wear-resistant than most OEM threads. During installation they cut their own threads and lock themselves permanently in place.

It is important to counterbore the pilot hole in order to ensure the TUF-THRED starts cutting straight into the parent material. In certain applications, using stainless steel TUF- THREDS, it may be necessary to tap with the appropriate thread size for the external thread of the TUF-THRED being installed. STEP. Select a bolt to use as an installation tool. The diameter and thread size of this bolt will be the same as the original thread size. A grade 8 bolt is preferred. Install a hex nut on the bolt turning it up the bolt until the amount of thread showing below the nut is about 3/4 of the overall length of the TUF-THRED. Now turn the TUF-THRED onto the bolt until it stops against the nut. The small holes in the TUF-THRED face the end of the bolt and must remain open for chip clearance. STEP 3. Carefully align the TUF-THRED to the drilled hole. It is critical that the TUF-THRED be started straight. For 3/8, 7/1, 1/, 9/1, 5/8, and 3/4 sizes, the counterbore described in step 1 insures a straight start. Using a wrench on the stop nut, turn the TUF-THRED into the hole until it is flush with the surface of the repaired item. You will feel the TUF-THRED cut its own threads as it goes in. Break the stop nut loose while holding the hex head of the bolt with another wrench. Remove the nut and bolt. regulations set by OSHA and ANSI safety code B7.1, and assumes all other risks

They are an efficient, cost effective way to repair large threads in heavy equipment. M a d e f r o m c h r o m i u m - molybdenum alloy steel they are hardened t h ro ug h ou t f or maximum strength and load distribution. Exterior threads are rolled for superior strength. They are as hard, or harder, than even premium grade fasteners. Properly installed, they will last indefinitely. They are installed by drilling out the old threads using standard fractional drill bits. Tap the resulting hole with a standard tap. (See chart for correct tap sizes.) Then screw in Tuf-Thred using a common bolt and nut as an installation tool. Tuf-Threds are designed to be locked in place mechanically (pinning) or with an anaerobic sealant such as Loctite #71. Standard sizes listed work best for most applications. Heavier versions are intended to repair major damage or to replace other manufacturers soft inserts. Thinwall TufThreds are designed to repair threads with minimum removal of the parent metal. Strength: Assuming proper installation, the tensile pull-out strength of TufThred inserts depends on: (1) the size of the outside thread, () the length of the insert, and (3) the shear strength of the parent material. All Heritage Oversize TufThred inserts are designed to provide a theoretical pull-out strength greater than a grade 8 fastener of the size of the inside thread when the insert is installed in any material with a shear strength greater than cast aluminum (,000 psi). Sizes other than those listed are available with with short lead times at reasonable cost.

STEP. Tap the drilled hole with a standard tap of the correct diameter (See chart following page). Clean the resulting tapped hole with a non-residue degreasing cleaner. STEP 3. Select a bolt to use as an installation tool. The diameter and thread size of this bolt will be the same as the original thread. A grade 8 bolt is preferred. Install a hex nut on the bolt turning it up the bolt until the amount of thread showing on the bolt is about equal to the overall length of the Tuf-Thred. Now turn the Tuf-Thred onto the bolt until it stops against the nut. STEP 4. If you plan to use an anaerobic sealant (such as Loctite #71) as a locking device, clean the outside threads of the Tuf-Thred with a non-residue degreasing cleaner and coat these threads with sealer now. Be careful that none of the sealer gets on the inside threads now or during insertion. STEP 5. Using a wrench on the hex nut, turn the Tuf-Thred into the hole until it is flush with the surface of the repaired item. Break the nut loose while holding the hex head of the bolt with another wrench. Remove the nut and bolt. If an anaerobic sealant has been used as a locking device, allow 4 hours at room temperature for curing before reassembling.
