POWERLOK® fasteners are designed for use in tapped holes, and are designed to be thread-locking and vibration resistant. TAPTITE® fasteners form their own threads in untapped holes as they are being installed. They also have excellent vibration resistance, and make excellent electrical grounding screws.
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. TAPTITE® fasteners manufactured from stainless steel are not recommended for thread forming into stainless steel or steel. Instead, they are best used in non-ferrous metals like brass, copper, and aluminum.
Yes, TAPTITE® fasteners manufactured from stainless steel will easily thread form into nonferrous metals such as those listed above.
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.
Yes. A TAPTITE® fastener does require more torque than a machine screw because the screw forms its own threads in an untapped hole, eliminating the need and extra cost of pre-tapping.
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. A TAPTITE® fastener has reduced lobulation on its body, is very close to round, and is slightly larger in diameter than machine screws. In fact, they have a slightly greater cross section than machine screws. As such, a TAPTITE® fastener will typically strip at a higher values than a machine screw.
