Single Sizes

Which size and type

You choose a single socket per size. First pick the drive: 1/4 inch, 3/8 inch or 1/2 inch. Then select the metric socket size. This way you build a set that matches your work. Check that the size you need is actually available. Not every size comes in every drive.

Where ordering goes wrong

A common mistake is choosing the wrong drive. A 1/2 inch socket does not fit a 3/8 inch ratchet. Measure the square drive on your ratchet or check the marking on an existing socket. Pick the wrong size and you will have to return it. Also check the socket size: it is marked in millimetres on the side.

Profile and finish

The profile determines how the socket grips the bolt. A hex profile is less likely to round off than a twelve-point profile. The finish protects against rust and makes cleaning easy. Many models have a hanging hole. That way you hang them back on the tool wall after use.
