Hex cap screws are partially threaded and provide much tighter tolerance than their fully threaded counterparts. Hex bolts are the most common construction fastener having a hex head that can be secured with a socket or wrench and mated with a nut or another internally threaded item.
External hex drives can be turned with an adjustable wrench, combination wrench and 6- or 12-point sockets and offers high torque transfer.
Hex Bolts meet all DIN, ISO, and ANSI specifications for a product that is strong and reliable.
