QA1 Jam Nut - 5/16-24 Right Hand - 1/2in Hex 3/16in Wide - Aluminum - 6 Pack

When you're working on engine components and need to secure a threaded rod or shaft, a jam nut is a simple but effective part. This set from QA1 gives you six aluminum jam nuts, each with a 5/16-24 right-hand thread. They feature a 1/2 inch hex size, making them easy to tighten down with a standard wrench.

These jam nuts are made from aluminum and come with a clear anodized finish. Aluminum is a good choice for applications where weight is a concern, and the anodized finish helps protect the surface. You get six pieces in this pack, so you'll have spares or enough for multiple small jobs.
