TAPTITE PRO® thread forming screws advance current thread forming technology with the development of the Parabolic Profile™ thread form. The innovative new thread form, when combined with the proven TRILOBULAR® cross section, provides low thread forming torque, excellent resistance to vibrational loosening along with high axial pullout and reduced overall cost of assembly. In addition to these great benefits, TAPTITE PRO® screws maintain torque tension relationships comparable to machine screws of equivalent size. TAPTITE PRO® fasteners also provide an improved failure mode; as a result of over-tightening in standard lengths of engagement, the screw will fracture within the screw threads.
