Frequently Asked Questions

Common questions related to REMINC and CONTI fasteners.
What are the differences between POWERLOK® and TAPTITE® fasteners?

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.

Can TAPTITE® screws cross-thread at assembly?

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.

Can TAPTITE® fasteners be used in pre-tapped nut members?

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.

Can a machine screw be installed into a tapped hole created by a TAPTITE® fastener?

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.

Can TAPTITE® fasteners be installed into unthreaded holes that are filled with paint?

Yes! Holes contaminated by paint or weld splatter will not prevent a TAPTITE® fastener from forming its internal threads.

If a tapped hole is contaminated with paint and will not allow a machine screw to be inserted, would a TAPTITE® fastener work?

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.

What would REMINC / CONTI suggest for an application where a conventional machine screw is constantly coming loose?

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.

A locking screw is to be installed into a tapped hole, but the tapped hole is contaminated with paint. What product might be used?

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.

Can a stainless steel TAPTITE® fastener be used to form threads in stainless steel or steel nut members?

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.

Can a stainless steel TAPTITE® fastener form threads in nonferrous metals such as copper, brass, aluminum, etc.?

Yes, TAPTITE® fasteners manufactured from stainless steel will easily thread form into nonferrous metals such as those listed above.

Can TAPTITE® fasteners be reinstalled or do they re-tap?

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.

Can TAPTITE® fasteners be used more than once in a tapped hole?

Yes, TAPTITE® fasteners can be reused repeatedly in a tapped hole, and still retain a level of resistance to vibrational loosening.

Does a TAPTITE® fastener require more torque than a machine screw to be installed?

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.

Because of the TRILOBULAR™ cross section, does a joint assembled with a TAPTITE® fastener rust more quickly than a joint assembled with a machine screw?

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.

Does a TAPTITE® fastener strip more easily than a machine screw because of its TRILOBULAR™ shaped cross-section?

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.
