Use for adjusting air brakes. Fits perfect. Good finish, use daily and still looks new. Great price for a professional tool.

It works perfect for the 5R55S. Used this for a ‘10 Mustang transmission rebuild.

If you looking to use on slack adjusters on heavy duty trucks, it works awesomeness. Not for all situations. But for my fleet of 9200's, it's a game changer. Kind of like when they came out with flip phones....it changed the world. Don't know what else you'd use it for.

I am a diesel mechanic and needed this tool and snap on wanted $30 for a similar design. Glad I looked on Amazon. Now my coworkers have ordered the same tool. A must have tool for air brakes and it’s not going to hurt your wallet.

That band adjustment screw that won't take a six or twelve point socket? Use this or a double square of the same size.

So if anyone has had to adjust semi brakes...some adjusters use 5/16 square head. I've destroyed open end wrenches and had a few knuckle busters until I decided to get one of these sockets. This is a must have for semi truck mechanics

I used this socket to mate with a 5/16-inch square-taper screw extractor (to remove a broken spark plug). We (two people) worked a 15-inch breaker bar and a lot of force on this and it stood up to the test. Yes, we did get the broken spark plug extracted (to took an hour and over a hundred hard pulls). Highly recommended for this use. I actually picked up the 3/8, 1/4, and this 5/16-inch square socket because I wasn't sure which extractor I would eventually use. The socket is covered by masking tape in the photo to keep the extension/socket/extractor assembly together as it was dropped into the recessed spark plug hole, but you get the picture. This socket was essential in this job.
