5/16-18 x 5/8 Oval Point Alloy Steel Socket Set Screw with Nylon Insert fits applications that need a headless internal-hex screw, rounded point contact, and a locking 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.

Packaging equipment and indexing stations may specify the insert when repeated motion would otherwise relax the setting.

Cold Headers supports distributor, OEM, and maintenance sourcing when an oval point part must match the existing print. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
