7/16-20 x 1/2 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is a heat-treated alloy steel flat point socket set screw with a nylon insert for prevailing torque. Use this style where the assembly needs a broad bearing face and a separate thread-locking feature. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.

Instrument and control components may need the no-mark behavior of a flat point along with an internal hex drive.

The 7/16-20 fine-thread rows are uncommon in this flat point locking family, so exact thread identification is important. Cold Headers can help identify the correct flat point alloy set screw when the drawing calls out a locking insert. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
