How to read the sizes of the Shockwave socket 1/2 18 x 38 mm

The designation 1/2 refers to the connection on your ratchet or other drive tool. The 18 is generally the width across flats in millimetres, so the size of the nut or bolt the socket fits around. The 38 mm is the length of the socket. If you want to be sure of the dimensions, compare the details on the page with the size of your fastener.

Who is this socket suitable for

A socket with a 1/2 inch drive suits work where you apply a bit more force to the fastener, for example in construction, installation, industry and renovation. If you use an impact wrench or impact driver, first check whether the socket is intended for that. Not every socket is made for machine tightening. If in doubt, ask us before you order.

What to look out for when choosing a socket

First check the drive size of your tool and then the width across flats of the fastener. A socket that fits the nut well transfers the force evenly and is less likely to damage the corners. Also pay attention to the length: a longer socket reaches recessed fasteners more easily, a shorter one is handy in places with little space.
