Has a similar thread design as a socket cap screw. The dome-shaped head is wider and has a lower profile than a socket cap screw. Used when a wider bearing surface or a smoother, more finished appearance is desired. Button head cap screws do not afford the strength of socket head cap screws and are designed for light fastening applications. They are not recommended for critical, high strength applications.

  • Thread: Coarse / Full Thread / Alloy Steel / Black Oxide
  • Recommended Hex Socket Allen Key Wrench: 3/16
  • Black Oxide is not a protective finish and will rust if exposed to moisture. Stainless Steel material is recommended for environments with moisture
