Product Identity

This pack contains eight 3/8"-16 hex nuts made from nylon by Midwest Fastener Corp. They are designed to mate with standard machine screws and bolts of the same thread size. The nylon material provides electrical insulation and vibration resistance in fastening applications. Suitable for general hardware tasks where non-conductive fasteners are preferred.

Who This Suits

These nuts suit technicians and DIY users who need a small quantity of insulated fasteners for 3/8"-16 threads. They work well for electrical enclosures, automotive accessory mounts, and lightweight assemblies. Builders who need metal threads for high-torque structural joints or buyers who want more storage options should look at alternative hardware types.

Thread Specification

The critical specification is the 3/8"-16 unified coarse thread pitch, which determines compatibility with matching bolts and screws. Only fasteners with this exact thread designation will engage correctly. Verify the thread requirement of your application before purchasing to ensure proper fit.
