7/16-20 x 1/2 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.

Grooved-shaft assemblies use the oval point to ride the groove while helping retain axial position.

Pelletized oval point screws keep the thread-locking feature separate from the adjustable contact geometry. The 7/16-20 rows are fine-thread-only in this oval point locking family, so exact thread identification matters. 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.
