I was cleaning the garage tonight and found a 3/8" deepwell socket set (shown below) that I must have received as a gift or something. This thread got me thinking about trying to see just how hard I have to pull to break a socket. I put a carriage bolt with two double nutted 3/4" nuts in my vice so that the vise had the bottom nut and the socket was on the top nut. I put a 1/2" to 3/8" adapter on the HF 3/4" socket and went to town with a long 1/2" breaker bar. I was really surprised that the socket didn't break before the carriage bolt was twisted in half. Then I got a plow bolt with a grade 5 nut and put it in the vise. I actually started pulling so hard that I put on a face shield and work gloves for when the socket cracked. It never did. When the plow bolt started to slip and get distorted in the vise I moved everything down a bit so that the vise had the bottom half of the grade 5 nut and the socket had the top half of the nut. The bottom half of the nut actually rounded completely in the vise and the socket never broke. I may get some more grade 8 hardware this week a just to see how hard I will have to pull to break this socket.
I'm not planning to replace my Craftsman sockets with the HF stuff, but I am more than a little impressed that a socket from a set that goes on sale for like $12 didn't break.

My ex-wife bought me some of those years ago, I thought they were funny, especially the colors. I threw them in my travel box, and bring the whole set underneath cars to keep from getting up for the right size all the time. Many years later, the colors are all but worn off, and the function of the abused sockets are 100%
Nothing short of a 3/4 inch impact gun will break them, so just give up, trying to break them by hand and leverage, the fasteners will break first.
Those are Harbor Freight tools from Taiwan. Maybe weld the heads of a Snap-on socket and one of those HF sockets together and put an impact gun in each one, and it will be like a socket truck pull LOL
Those "prisy" sockets are tough! LOL I laugh every time I hammer them onto a rust salvage yard bolt and give them the muscle. Unbelieveable how strong they are.
Funny! yes, but true.
