Engineered Fastening Thread Rolling Fasteners

Unique Design Increases Performance TAPTITE 2000® fasteners are designed to provide the benefits of previous TAPTITE® fastener products with an innovative new thread design – the Radius Profile™ Thread. The proven TRILOBULAR® principle is maintained while incorporating this beneficial thread design. The result is a new generation of TAPTITE® fasteners, providing excellent mechanical, assembly, and ergonomic characteristics surpassed by no other technology. TAPTITE 2000® fasteners afford end-users with enhanced opportunities to reduce the overall cost of assembly. TRILOBULAR® Configuration • Reduces...

Built On Proven Performance TAPTITE® fasteners have been used in a variety of industries since its inception over forty years ago. Built upon those years of experience with the proven performance features of TAPTITE®, TAPTITE II®, and Duo-TAPTITE® fasteners, the TAPTITE 2000® design combines all these previous benefits with an even lower thread-forming torque. The result is optimal joint performance in a wide range of applications. Application Comparison Lowest thread-forming torque Positioning applications Structural applications High torque-tension applications High strip-out requirement Automation...

TAPTITE 2000® Standard Fasteners Hole Sizes per Percentage of Thread Engagement – Metric Sizes (mm) 100 Nominal Screw Size Hole Sizes per Percentage of Thread Engagement – Inch Sizes (in.) Nominal Screw Size NOTE: Nominal screw diameters are used when calculating hole sizes and are based on the U.S. basic thread depth of 0.6495 times the pitch. Hole data accuracy decreases for engagements less than 70%. This is because the above data is based on a linear relation between hole size and percentage of thread engagement. Hole Size = D – (0.6495 x P x %). In this equation, D is equal to the nominal...

Special Point Designs TAPTITE 2000® CA™ Point Fasteners TAPTITE 2000® CA fasteners have a gimlet point for use where clearance holes and pilot holes do not align. The CA point is also good for rapid hole finding, floating nut members or difficult access applications. The CA point can be supplied with a sharp point or a slightly truncated blunt point, which is desirable for situations when the sharp point could be a potential hazard to wires, components or assembly line and service personnel. Taptite 2000® "SP"™ (Short Point) Fasteners TAPTITE 2000® "SP" fasteners have a shorter point than standard...

TAPTITE 2000® "SP"™ Fasteners Recommended Pilot Hole Sizes for Aluminum or Zinc Alloy Die Castings for TAPTITE 2000® "SP™ Fasteners The minimum length of thread engagement should be equal to twice the diameter of the screw (to approach utilizing available screw strength). To ensure optimum performance, the hole diameter should provide for 65% to 75% thread engagement.
