Quality is not good
Unfortunately after using about 5-7 times the socket is useless. Metal is very soft I guess as those lines got stripped pretty quickly. No warranty as seller responded. I would not recommend

This is what it is, it fastens tri-nuts. I ordered the #30 for 3/8 bolts but the bolt would not go deep enough into socket to tighten nut completely it was necessary to run 3/8 drill bit through - easy enough.Manufacturing issue not sellers arrived on time and it is what I ordered

Hence 4 stars not 5
