  • Button socket cap screws have a similar thread design as a regular socket cap screw with the most noted difference being the wider, dome-shaped head and lower profile
  • Button socket cap screws are used when a wider bearing surface or a smoother, more finished appearance is desired
  • They are not recommended for critical, high strength applications
