High Performance Thread Rolling Screws for Metals

1 TAPTITE 2000 FastenersHigh Performance Thread Rolling Screws for MetalsTAPTITE 2000 TAPTITE 2000 Thread forming technology joins two unique concepts and advances fastener Performance to new levels. TAPTITE 2000 fasteners afford end-users with enhanced opportunities to reduce the overall Cost of Assembly. TAPTITE 2000 fasteners are designed to provide the benefits of prior TAPTITE fastener products with an innovative new Thread design - the Radius Profile Thread . The proven TRILOBULAR principle is maintained while incorporating the Radius Profile Thread . The result is a new generation of TAPTITE 2000 fasteners which provide excellent mechanical, assembly, and ergonomic characteristics surpassed by no other Design GuidelinesTAPTITE 2000 HEAT TREATMENTTAPTITE 2000 bolts perform well in large diameter sizes in deep Thread engagements.

2 In the past, the limitations of case-hardened products restricted the exploitation of in-place cost savings for larger diameter TRILOBULAR fasteners. However, TAPTITE 2000 Screws and bolts are available with 3 different types of heat treatment: CORFLEX - I , CORFLEX - N , and case hardened, making the fasteners adaptable to a wider variety of applications. CORFLEX - I Heat Treatment - CORFLEX - I TAPTITE 2000 bolts are neutral hardened to Class , , or any intermediate value. The Thread forming zone is selectively induction hardened in order to form threads in untapped nuts.

3 CORFLEX - I heat treatment allows TAPTITE 2000 Thread Rolling bolts to provide in-place cost savings in large structural applications with strength, ductility and toughness equal to comparable machine Screws or bolts. CORFLEX - I heat treatment to Class level is standard for TAPTITE 2000 bolts in sizes M6 (1/4 ) and larger. CORFLEX - N Heat Treatment - CORFLEX - N TAPTITE 2000 fasteners are neutral hardened to Class strength level. CORFLEX - N products are designed to be used in soft white Metals such as aluminum or zinc alloys. CORFLEX - N heat treatment can be specified for any size TAPTITE 2000 screw or bolt that is intended to be used in aluminum or zinc alloys.

4 Case Hardening - Case hardening is the standard heat treatment for all TAPTITE 2000 Screws in sizes M5 (#12) and to 12 to 13 to 14 to 15 to 16 to 17 to 1 NEWTONSL ower Starting End LoadTAPTITE 2000 fasteners require low axial end load to initiate Thread Drive-to-Fail RatioThe higher, more uniform, drive-to-fail ratio of TAPTITE 2000 bolts provides a built-in safety factor against 2000 Thread Rolling BOLTROUND BODIED Thread Rolling B O LTNOTE: End load and drive-to-fail ratio graphs shown are based on average results recorded when testing in unthreaded steel weld nut having a diameter of the TAPTITE 2000 FastenerTAPTITE 2000 Thread Rolling BOLTROUND BODIED Thread Rolling B O LT Ergonomically Friendly Assembly Friendly Superior Vibration Resistance Excellent Axial Alignment Low End Load high Drive-to-Fail Ratio high Prevailing Torque Excellent Torque-Tension Relationship2 Radius Profile Thread DesignFor M6/1/4 and LargerFor M5/#12 and SmallerRadius Profile Thread DesignFor M6/1/4 and LargerFor

The hole diameter, to ensure optimum Performance , should provide for 65% to 75% Thread 2000 SP fasteners have a shorter point than standard TAPTITE 2000 fasteners to maximize the full Thread engagement in blind holes, particularly in non-ferrous materials. TAPTITE 2000 SP fasteners are primarily used in aluminum and therefore are supplied with CORFLEX - N heat treatment to minimize the potential of stress corrosion.

10 When used in steel material, TAPTITE 2000 SP fasteners can be ordered with case hardened or CORFLEX - I heat treatment. The short (2 - 2 1/2) point of the TAPTITE 2000 SP fastener increases the amount of full Thread engagement in blind holes. Increasing the full Thread engagement is often critical in shallow depth holes. In many cases the failure mode can be changed from internal nut threads stripping to the fastener breaking, which is usually desired in castings. In deeper holes, the shorter SP point may allow a shorter fastener, saving weight and 2000 SP Fasteners6 TAPTITE 2000 7 Torque Performance / Pilot Hole SizesNominal screw SizePlate ThicknessHole SizeNearest Drill SizeThread Forming TorquePrevailing First Removal TorqueRecommended Assembly TorqueFailure # - - - - - - - - - # - - - - - - - - - # - - - #.
