5/16-24 x 3/16 Oval Point Alloy Steel Socket Set Screw with Nylon Insert is chosen when an oval point should ride a prepared groove while the nylon insert resists backing out. 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.
Spline-adjacent and keyway-adjacent seating may call for a rounded point where sharp engagement would be too aggressive.
In-house pellet installation supports uncommon oval point nylon-insert requirements when a standard plain screw is not enough. 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.
