About Socket Head Cap Screws
Perfect for tight spots, socket cap screws enable drive where there is not enough space for a wrench or socket. Instead, they are installed with a hex key. Flat socket head cap screws pair with flat washers to sit flush with surfaces while button head cap screws have a low-profile, rounded head which fastens thin surfaces that can’t be counterbored. Be sure to choose the right thread size, head type and hex nut to use in conjunction with your cap screw.
