[10 PKG] Hex Jam Nuts 18/8 Stainless Left Hand 5/8-18

Hex Jam Nuts 18/8 Stainless Left Hand 5/8-18 are compact locking nuts designed for secure, vibration-resistant fastenings in left-hand threaded assemblies. These jam nuts tighten against a standard nut to prevent loosening in demanding applications.

The left-hand thread means they are designed to mate with 5/8-18 left-hand bolts, providing a reliable locking solution where a standard right-hand fastener would loosen under operation.
