7,755 products
Socket head cap screws feature a hexagonal recess for tightening and loosening using an Allen wrench or hex key. This design eliminates the need for side clearance and allows screws to be placed close to other screws and assembly components. They come in a variety of head configurations that can fit into tight spaces, reduce the chance of snagging, or provide a flush fit with the fastening surface.
Inch System Standard Socket Head Cap Screws
Inch standard socket head cap screws are measured and manufactured in imperial or inch units. They have cylindrical heads that are approximately the same height as the screw shank diameter.
