QA1 Jam Nut - 3/8-24 Left Hand - 9/16in Hex 7/32in Wide - Steel

This steel jam nut features a 3/8-24 left-hand thread, meaning it tightens in the opposite direction of most standard fasteners. It has a 9/16 inch hex size, which is a common wrench size, and the nut itself is 7/32 inches wide. This makes it a solid choice for securing components where a reverse thread is needed, such as on certain rod ends or adjustable linkages.

Built from steel, this jam nut offers good strength for its size. While QA1 also offers these in aluminum with a clear anodized finish for lighter weight applications, this steel version is a dependable option for many engine and chassis setups. It's designed to lock down and prevent other components from loosening due to vibration or movement.
