5/16-18 x 5/16 Oval Point Alloy Steel Socket Set Screw with Nylon Insert identifies the exact thread and length for an alloy steel oval point set screw with a nylon insert. The nylon insert works in the female thread, adding prevailing torque while the oval point handles surface contact. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.
Fine-thread 7/16-20 and 5/8-18 rows help match uncommon oval point locking requirements that are easy to mis-source. Alloy steel is not the corrosion-focused option, so use protective oiling or a stainless request when exposure requires it.
Cold Headers focuses on exact-size socket fastener sourcing for production cells, repairs, and plant maintenance programs. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
