5/16-18 x 7/16 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. Use this style where the assembly needs rounded contact and a separate thread-locking feature. 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. Alloy steel is not the corrosion-focused option, so use protective oiling or a stainless request when exposure requires it.
Pelletized oval point screws keep the thread-locking feature separate from the adjustable contact geometry. Cold Headers can help identify the correct rounded-point alloy set screw when a drawing calls out a nylon insert. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
