What are 1/4 inch sockets used for?

1/4 inch - Used for smaller sockets and precision work. Useful for dismantling individual components on the bench. 1/2 inch - 1/2" sockets are generally used for nuts and bolts from around 10mm and up.

Are 6 or 12 point sockets better?

Answer: It's true that 12-point sockets are fine for most lightweight repairs, but heavy wrenching calls for a six-point socket. A six-point socket is much less likely to slip off a stubborn fastener or round over the corners. Here's why: (1) Six-point sockets have thicker walls, so they're less likely to flew.

Is 10mm same as M10?

If the size is M10 x 25, that would mean that the diameter is 10 mm. Since there is no thread pitch listed, the fastener is assumed to have a coarse thread. The 25 indicated a length of 25 mm. A matching nut would be labeled M10, which also doesn't require a thread pitch since it's a course thread fastener.

Should I get metric or SAE sockets?
