PennEngineering® is a licensee for MAThread® anti-cross-threading technology. Originally developed for the demands of the automotive industry, this patented design helps speed assembly and reduces or eliminates failures, repairs, scrap, downtime, and warranty service associated with thread damage.

This unique anti-cross-threading feature is offered on most PennEngineering externally threaded products including studs and panel fasteners. Now, in addition to automotive, other manufacturers of medical, recreation, telecom/datacom, avionics, and computer equipment can all benefit from this advanced thread technology.

How It Works

MAThread® illustration misaligned axis

Misaligned Axis

The versatile MAThread design allows the designer to select the point shape best-suited to feed well in the application.

Threads Cam

As the threads come into contact, the patented anti-cross MAThread design begins to cam over the female thread.

Threads Drive Normally

The MAThread design forces the two thread helixes to align every time without fail. The fasteners then drive easily with reduced effort.
