Frequently Asked Questions

Can I run it on a breaker bar?

Yes. With a 1/2" square drive it takes a ratchet, an extension or a breaker bar when a fastener needs more leverage.

Will it survive an impact gun?

It is not intended to. Hand sockets are made for steady turning force, so reach for an impact-rated version if you are working with an impact wrench.

Will a nearby size do instead?

Better not. A hex profile only grips properly at its own size, so H12 is what you want if that is what the fastener takes.
