Sockets are used to tighten or loosen nuts and bolts and they are used a lot in DIY car repairs. They allow you to work in confined spaces within the engine and to loosen very difficult-to-turn fasteners - which every engine has lots of! They work by fitting over the nut or bolt and attaching to a handle or ratchet. This then acts as a lever, allowing you to apply more pressure than you could with your hand and also to keep hold of the bolt in the socket while you are working - preventing slips or other mistakes. Choose from our range of quality sockets from respected manufacturers. These will allow you to carry out a wide range of DIY car jobs. If you can't find the socket size you are looking for then get in touch and we will help.
