5/8-18 x 1/2 Oval Point Alloy Steel Socket Set Screw with Nylon Insert is the nylon-insert version of an oval point socket set screw for compact industrial adjustment assemblies. The internal hex drive keeps the screw headless and accessible in collars, hubs, handles, and compact control parts. 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. When maximum bite on a plain shaft matters more than adjustability, compare Cup Point Alloy Set Screws with Nylon Insert.
Cold Headers installs nylon locking pellets in-house at its Chicago facility for this oval point set screw family. The 5/8-18 rows are also fine-thread-only here, an uncommon locking oval point configuration. This catalog separates oval point locking screws from plain oval point parts so the insert requirement stays visible. Check size, socket, pellet dimensions, and seat condition before substitution.
