1/2-20 x 7/8 Cup Point Alloy Steel Socket Set Screw with Nylon Insert combines a cup point, internal hex drive, and nylon locking pellet in one headless fastener. The cup rim seats against the mating surface, while the nylon insert develops prevailing torque in the female thread.
Typical uses include collars and couplings on production machinery where a shaft-mounted component must stay adjusted. Confirm thread size, length, hex key size, cup point geometry, pellet diameter, and pellet location before substituting another set screw.
Cold Headers has supplied specialty socket fasteners since 1962 and helps buyers identify exact thread and length combinations. Nylon inserts are installed in-house at the Cold Headers facility in Chicago for this locking set screw family. This deep-size alloy nylon-insert range is useful when large-diameter locking cup point set screws are difficult to source by exact length.
