Trev's Vintage Machine Shop

This is a set of 1/4 UNF, 3/8 UNF & 1/2 UNF (Unified Fine) Aerotight locking nuts, made from stainless steel.

Each nut is an all-metal locking nut that grips the male thread, holding the nut safely and securely in position. They resist coming loose under vibration or torque. These distorted thread locking nuts are superior to nyloc nuts because they retain their locking ability at high temperatures, and they can be safely reused.

These are available in the following sizes:

Thread size	Width across flats	Depth	Spanner size
1/4 UNF (28 TPI)	0.436 in	0.308 in	Fits 7/16 AF spanner
3/8 UNF (24 TPI)	0.562 in	0.454 in	Fits 9/16 AF spanner
1/2 UNF (20 TPI)	0.748 in	0.617 in	Fits 3/4 AF spanner

They are sold in packs of 2, 4, 6, 8 or 10 nuts. These are new old stock with slight marks from storage. All items are dispatched quickly via Royal Mail 2nd Class, with tracked postage available at extra cost.
