1/2-20 x 3/4 Oval Point Alloy Steel Socket Set Screw with Nylon Insert is specified when tangent contact and thread-level locking are both required in a headless fastener. 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.

Packaging equipment and indexing stations may specify the insert when repeated motion would otherwise relax the setting.

For replacement work, Cold Headers keeps the thread, length, alloy material, rounded point, and insert requirement together. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
