Sockets are normally made from steel and are used with ratchet handles of various sizes. Combined together they provide more torque leverage than a spanner helping you to tighten or remove nuts & bolts.Unlike regular sockets, impact sockets have a hardened carbonized surface, also known as heat-treated or drop forged. This allows an impact socket to manage torque impact changes. Non-impact (standard) sockets will bend or break when used with an impact tool and this can be dangerous and cause injuries.Socket TypesHex is an abbreviation of Hexagonal and there are two types of Hex socket; 6-point and 12-point. A hex socket will fit naturally around a six-sided nut or bolt. A 12-point socket also fits around a hex bolt and this is also known as a bi-hex or double hex socket. A double hex provides more flexibility in confined spaces.Deep sockets, also known as deep dive sockets. The difference is they are longer than standard sockets and provide added accessibility in limited space and hard to reach parts.Insulated sockets are safe to work on live equipment up to 1000 V.
