TAPTITE® Thread-Rolling Fasteners
TAPTITE PRO® thread-forming fasteners – the most advanced products in the TAPTITE® family of fasteners.
Leveraging the latest advancements in thread-forming technology, TAPTITE PRO® fasteners offer even greater opportunity to save costs and ensure reliable performance in joint assembly.
Each TAPTITE PRO® fastener:
Failure mode of stripping in standard depths of engagement
Low end load
Low thread-forming torque
Efficient torque-tension relationships
Resistance to vibrational loosening
Resistance to axial pull-out
Parabolic Profile™ Thread Form
The innovative Parabolic Profile™ thread form, unique to TAPTITE PRO® fasteners, advances current thread-forming technology to the next level. This innovative new thread form provides the same low forming torque to reduce operator fatigue, maintains excellent resistance to vibrational loosening, and improves axial pull-out performance over previous generations of TAPTITE® fasteners.
Predictable Failure Mode
Every manufacturer has struggled with the costly implications created when an overtightened fastener results in stripped nut members or castings. The resultant waste, repair, and related downtime is often an unrecoverable cost. TAPTITE PRO® thread-forming fasteners feature a predictable failure mode that eliminates stripping issues. When properly used in standard lengths of engagement, overtightened TAPTITE PRO® fasteners will fracture within the screw threads. Rather than replacing or repairing costly nut members or castings, an overtightened joint will now consistently result in a broken fastener that can quickly be removed with a screw extractor. This design improvement was accomplished without sacrificing any tensile or torsional strength requirements.
TRILOBULAR® Cross Section
Like all screws in the family, TAPTITE PRO® thread-forming fasteners feature the distinctive TRILOBULAR® cross-section. These screws deliver the same superior vibration resistance, low thread-forming torque, high prevailing torque, and cross-threading elimination that have made TAPTITE® fasteners famous for generations.
TAPTITE PRO® "SP"™
TAPTITE PRO® SP™ fasteners are the short point (SP) version of the TAPTITE PRO® fastener, designed to accommodate limited
clearance applications like aluminum cored holes.
The TAPTITE PRO® SP™ fastener carries a single consistent out-of-round with moderate lobulation. The point of the TAPTITE PRO® SP™ fastener is a shorter, 2 - 2 1/2 point tapered lead thread design.
The end result maximizes thread engagement without the added cost of increased core pin length.
TAPTITE PRO® "CA"™
The TAPTITE PRO® CA™ fastener features a CA point that is ideal 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,
desirable for situations when the sharp point could be a potential hazard to wires, components or assembly line and service personnel.
TAPTITE 2000® thread-forming technology joined two unique concepts and advanced fastener performance to new levels.
Hitting the market in 1998, the TAPTITE 2000® family of fasteners introduced an innovative new thread design - the Radius Profile™ thread. The proven TRILOBULAR® principle is maintained with a dual lobulation in the screw body, while incorporating the Radius Profile™ thread.

Introduced in 1979, the DUO-TAPTITE® fastener was the first fastener in the TAPTITE® family to feature Dual Lobulation - two distinct out-of-round profiles along the screw body.
DUO-TAPTITE® screws have generous lobulation at the screw point for easy entry and optimum thread-forming action plus reduced lobulation in the screw body holding area. A stabilizing threaded dog point ensures ready, aligned entry, with easy pickup requiring minimal starting end load.
Introduced in 1990, the TAPTITE II® fastener improved upon the original TAPTITE® fastener design.
With a more efficient manufacturing method and an improved tool design, TAPTITE II® screws produced an even more consistent product. Torque performance was made more uniform, thread-forming torque was lowered, and the net result was a consistent part that integrated well with emerging SPC production philosophies.
