5/8-18 x 5/8 Oval Point Alloy Steel Socket Set Screw with Nylon Insert uses a rounded oval point to reduce marking while the insert adds friction in the mating thread. The rounded oval point can make tangent contact on flat, angled, curved, or grooved mating surfaces. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.

Linkage and lever assemblies may use this point style where the screw meets the mating part at an odd angle.

The 5/8-18 rows are also fine-thread-only here, an uncommon locking oval point configuration. Cold Headers can quote the requested oval point nylon-insert item without steering the request toward a biting point style. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
