Button head cap screw

Listing ID #4280287

Has a similar thread design as a metric socket head cap screw. However, the dome-shaped head is wider and has a lower profile than a metric socket head cap screw. Generally manufactured in accordance with ISO Standard 7380. 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.
