OVERVIEW

Industrial Grade Stainless Steel Coupling Nut

The 5/16"-18 x 1-1/4" Stainless Steel 18-8 Coupling Nut is a specialized fastener designed for joining two male threads, commonly threaded rods, of the same diameter and pitch. Manufactured from 18-8 stainless steel (equivalent to 304 grade), this component offers significant resistance to corrosion, oxidation, and chemical degradation, making it an essential hardware item for maintenance, repair, and operations (MRO) in harsh industrial environments.

With a standard Unified National Coarse (UNC) thread pitch of 18 threads per inch, this coupling ensures compatibility with a vast array of standard bolts, studs, and rods. The 1-1/4 inch length provides extended thread engagement, which distributes the tensile load across more threads, reducing the risk of stripping under tension. This is particularly critical in suspension applications or when extending tie rods in machinery.

The hexagonal exterior profile allows for easy tightening with standard wrenches or sockets, facilitating quick installation and adjustment. Whether used for hanging fixtures, repairing machinery, or fabricating custom assemblies, this stainless steel coupling nut delivers the reliability and strength required for professional applications. Its non-magnetic properties (in annealed condition) and clean finish also make it suitable for applications requiring a high degree of hygiene or aesthetic appeal.

FAQ

It is made from 18-8 Stainless Steel, which is chemically equivalent to 304 Stainless Steel, offering excellent corrosion resistance.

The thread is 5/16"-18, which is a standard coarse (UNC) thread.

The total length of the coupling nut is 1-1/4 inches.

Yes, that is the primary application. It allows you to join two 5/16"-18 threaded rods end-to-end.

Because it is made of 18-8 stainless steel, it is highly resistant to rust and suitable for most outdoor applications.

You will typically need a standard wrench or socket that matches the hex size (usually 1/2" for this thread size, though it can vary).
