For drawings calling out a nylon insert socket cap screw, the 5/16-18 x 1 1/2 1960 Series Alloy Steel Socket Head Cap Screw with Nylon Insert provides exact thread-and-length identification. Its nylon insert creates a frictional locking action in the threaded joint while preserving top-side internal hex drive access for installation.
In maintenance repairs, replacement assemblies, and retrofit work, the internal hex drive allows compact tool access while the alloy steel body keeps the product aligned with drawings that specify this material. Review thread size, length, mating material, available drive access, and insert location before release to production or maintenance use.
Since 1962, Cold Headers has helped industrial buyers source specialty socket products, unusual lengths, and replacement configurations.
