2-56 X 1/2 BUTTON SHCS ALLOY
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 a socket head cap and are designed for light fastening applications. They are not recommended for critical, high strength applications.
