Triumph BSA Pre-Unit Unit 500 650 Front Axle Polished Standard Nut (1) PN# 37-1246 W1246 42-5842

The axle nut is important as it locks down the brake anchor plate to the front hub spindle.

The thin axle nut is threaded with 20 TPI CEI threads for fitment onto the full-width cast iron front hub spindle. Suitable for use on BSA and Triumph models from 1958-1968. Made in the UK.

The thin nut is threaded onto the front hub spindle, locking the brake anchor plate to the spindle. When properly installed, it prevents the brake anchor plate from rattling on the fork locating tab.
