Airframe (AN) & Mil-Spec (MS) Nuts

Keeping a racecar bolted together can be a challenge due to the extreme forces and vibrations involved. This is why we stock an extensive selection of female-threaded nuts manufactured to various aircraft and military standards.

We stock half-height and full-height self-locking nuts, Castellated nuts for use with cotter pins, and Jam nuts for locking down the adjustment on Aurora rod ends or any other fixture that requires a positive locking fit.

Finish off your assembly with Cross Check lacquer for a fool proof way of monitoring loosening fasteners.
