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.
