1/4-28 x 1/2 Oval Point Alloy Steel Socket Set Screw with Nylon Insert gives purchasing teams a specific alloy steel oval point nylon-insert size for replacement work. Oval point geometry favors adjustable contact and re-seating rather than maximum bite into the mating part. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.

Machine rebuilds use this family when the service record calls for alloy steel, an oval point, and a nylon insert. The polymer insert changes the service envelope versus an all-metal screw, so review heat exposure before specifying it.

In-house pellet installation supports uncommon oval point nylon-insert requirements when a standard plain screw is not enough. 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.
