This Fox 1/2-13 x 2.125" button head cap screw is an alloy socket-style fastener suited for applications requiring a low-profile button head. The 1/2-13 thread and 2.125-inch length provide common heavy-duty fastening dimensions, and the socket button head form is used where a smooth, finished bearing surface and recessed drive access are desired in assemblies and mounting hardware.
