10-32 x 1/4 18-8 Stainless Steel Button Head Socket Cap Screw with Nylon Insert adds a nylon prevailing-torque element to a button head socket cap screw format. The locking pellet adds a prevailing-torque feature while the internal hex drive keeps installation compact from the top side.
The rounded button head can reduce exposed edges, spread bearing load over a broader face, and avoid counterbore machining when the assembly accepts a raised dome. Typical applications include retrofit vibrating guards, replacement covers, and maintenance panels, where exposed hardware benefits from a smooth dome and exact thread-length match.
The 18% chromium and 8% nickel austenitic stainless material is commonly chosen for general corrosion resistance, clean appearance, and ordinary moisture exposure. For flush countersunk installation instead of a dome head, review 18-8 Flat Head Cap Screws with Nylon Insert. Cold Headers has supplied specialty socket fasteners since 1962 and helps buyers source exact stainless sizes and uncommon lengths.
