8-36 x 5/16 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is specified when friction clamping and thread-level locking are both required in a headless fastener. Flat point geometry favors surface protection and repeatable adjustment rather than maximum bite into the mating part. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
Large 5/8 flat point nylon-insert sizes support heavier collars and hubs where the print still calls for shaft-friendly contact. ASME B18.3 places flat point diameter in a qualitative band of about 0.55-0.62 times nominal screw diameter, so confirm the mating seat rather than substituting a sharp point. Because the insert is polymer, review heat exposure when the application would otherwise use an all-metal screw.
Cold Headers has supplied specialty socket fasteners since 1962 and keeps point style, insert type, and size language clear. Check size, socket, pellet dimensions, and surface-marking tolerance before substitution.
