Steelman 3-1/2 Inch 6 Point Locknut Socket, 3/4 Inch Drive – Model 60258-10, SAE

Sometimes you just need a really big socket.

This Steelman is a 3-1/2 inch, 6-point socket designed for those giant locknuts you find on heavy equipment or truck suspensions.

It's got a 3/4-inch drive, so you'll need a decent-sized breaker bar or impact gun to turn it.

It's made in Taiwan and comes with a lifetime warranty, so Steelman stands behind it.

It's a single socket, not a set.

Just a heads-up, California has the usual Prop 65 warning on it.

If you're working on something that needs a socket this size, this is a solid, affordable option that'll get the job done.
