Metric Aerotight Nut, Stainless steel

An all metal self locking nut, also referred to as a stiff nut. Manufactured in A4 (316) stainless steel. The Aerotight Nut design means it can be re-used many times with the self locking function remaining effective even when not fully tightened. The all metal construction makes these nuts more resistant than many other self locking nuts with nylon inserts to high temperatures, humid environments and most chemicals.
