SUNEX TOOLS 310EPC 3/8-Inch Drive 5/16-Inch Female Pipe Plug Socket

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.

Life saver to adjust the bands on my 47re as is really a tight spot to work

Works as. It should

This is the perfect socket to adjust air breaks with ! The socket did what it was suppose to do . It grips well and it fits any 3/8 socket (obviously)

I love this tool!I used it to slack adjuster on tractor trailer,work well with a 3/8 ratch wrench.used it daily and its great!

I abused mine working on tractor trailers for over 4 years before it cracked. Good socket.

Worked perfectly for what I ordered it for

Works great. Quality is there.

This is a must have accessory for anyone with a mini mill with the appropriate sized drawbar.
