Button Socket Cap Screws

Button Socket Cap Screws
Product Details

Button socket cap screws have a wider domed-shaped head, wider bearing surface and high tensile strength but a lower profile than a socket head cap screw. The socket cap screws occupy much smaller space and can be installed in a deeper position. They can sink into the inside of the parts and are not exposed, so they can reduce the overall size and do not interfere with other components.


Button Socket Cap Screws are available in alloy steel with a black oxide finish and stainless steel. Standard and metric sizes are available.
