POWERLOK® II™ fasteners are designed for use in tapped holes their thread-locking action is vibration resistant. The TAPTITE® fastener family form mating threads in untapped holes as they are installed. They also have excellent vibration resistance and make excellent electrical grounding screws. TAPTITE PRO® screws were recently written into an major automotive standard as their default grounding fastener!
Absolutely not! TAPTITE® fasteners form their own threads in untapped nut members as they are being installed. This lowers the overall cost of assembly as pre-tapping the nut members is not required.
Yes, the TAPTITE® thread form was designed so that it would fit the envelope of a 6H (metric) or 2B (inch) nut member. Although TAPTITE® fasteners are designed to form internal nut threads at assembly, there are circumstances where TAPTITE® fasteners are used in pre-tapped nut members.
Yes, the TAPTITE® thread form was designed so that a 6g (metric) or a 2A (inch) standard thread form could be retrofit into a nut created by TAPTITE® screw.
Yes! Holes contaminated by paint or weld splatter will not prevent a TAPTITE® fastener from forming its internal threads.
Yes, a TAPTITE® product will force its way through the paint. Also, our KLEERTITE® product will scrape away the paint as it is being driven to provide good electrical conductivity.
POWERLOK II® fasteners would be recommended for this application. POWERLOK® is our all metal TRILOBULAR™ fastener for use in tapped nut members. The POWERLOK® screw achieves enhanced locking ability through the combination of a novel 60° - 30° thread form and a TRILOBULAR™ thread body. The 30° tip penetrates the root of the nut threads as the thread form locking feature. POWERLOK® screws resist vibration even when unseated as the locking feature extends the entire length of the fastener; therefore POWERLOK® fasteners make excellent adjusting screws.
KLEERLOK® is a fastener specifically designed for this type of application. It is a POWERLOK® fastener with a paint-clearing feature added to the point to completely scrape away the paint as it is driven. The POWERLOK® threads provide a vibration resistant assembly.
No. Stainless steel TAPTITE® fasteners are typically too soft to thread form into stainless steel or steel; they are best used in soft, non-ferrous metals such as aluminum or magnesium.
Stainless steel TAPTITE® fasteners will easily thread form into soft, nonferrous metals such aluminum, magnesium and many grades of copper or brass. A wax coating is recommend to avoid galling.
TAPTITE® fasteners can be reinstalled and will not re-tap. The fastener will find its own internal thread path due to the point tapered lead.
Yes, TAPTITE® fasteners can be reused repeatedly in a tapped hole, and still retain a level of resistance to vibrational loosening.
A TAPTITE® fastener sometimes requires bit more torque than a machine screw to achieve the same clamp force. However, because of the use of a post plate wax, or a finish with a lower coefficient of friction, the assembly can actually be less.
No. Extensive corrosion testing by an independent, accredited lab concluded that the performance of TRILOBULAR™ fasteners was no more adversely affected than that of machine screws.
No. TAPTITE PRO® and TAPTITE 2000® fasteners have reduced lobulation on its body and therefore is very close to round. They are also slightly larger in diameter than machine screws. As such, they will typically strip at a higher values than a machine screw.
