5/16-24 x 5/8 1960 Series 18-8 Stainless Steel Socket Head Cap Screw with Nylon Insert supports compact internal-hex fastening where a backed-out screw would create a service problem. The insert is positioned in the threaded body so the screw can develop prevailing torque during engagement.
In electrical enclosures, cabinet hardware, or field service assemblies, the internal hex drive keeps installation compact while the insert adds thread-friction locking action. 18-8 stainless is a practical choice for ordinary moisture exposure, washdown-adjacent machinery, and equipment where a clean stainless finish is specified.
For countersunk installations, 18-8 Flat Head Socket Cap Screws with Nylon Insert keep the locking feature in a different head style. Cold Headers supports industrial maintenance and OEM sourcing teams when difficult-to-find stainless socket products are specified. The 1960 Series name identifies the modern ASME B18.3 head-proportion standard for socket head cap screws, successor to the older 1936 series, not a year of manufacture.
