Just what I needed to torque down my driveshaft bolts. Worked as intended. Seems to be made of good quality. Very pleased with my purchase.

Once I've gotten drive shaft Bolts loose, I can then back bolt completely out using this socket with wobble extension

Very good price for an impact socket. 1/2 of FF price. Hard to find these as individual sockets. Usually have to buy the set. 12 point impacts also hard to find. Works great on the driveshaft yoke of my Ranger

I bought this and 3 other Sunex 12 point 12mm sockets and this made replacing the turbo on my LBZ as easy as it was ever going to get. Wasn't fun, but I can't imagine doing it with out those sockets. Replaced the 12 up-pipe bolts with ARP's and lottsa antiseize, and don't expect to ever have a problem with them again

I used it to change the front axels on an F150 with a ~90 ft-lb air-ratchet.These are the special 12 sided bolt heads with rust and Loctite. I used a 60flb torque wrench to tighten.After 1 full day of use there isn't any obvious wear and they fit the special 12 sided bolt heads
