HEX HEAD BOLTS

Hex-head screws are screws with a hexagonal-shaped head that can be tightened with a wrench (spanner) or socket, which engages with the external faces of the hex head. These types of fasteners have an external hexagon head and should not be confused with a hexagon socket head or an Allen — which has an internal hexagonal socket that can be driven by hex bits or keys.
