TONYNOL1/2 Inch Drive Deep Impact Socket Set,9 PCS,6-Point,Metric Size(29mm to 38mm),Cr-Mo Steel,Heavy Duty Impact Socket Set,With a Storage Case

I bought these for use around the shop. I have a 1/2in Electric Milwaukee Impact, and I wanted to see if it would take semi lug nuts off. I used a socket out of this set, and it was a bit slow going, but it did indeed knock about 12 of them off, before the impact started smoking. lol The socket was fine. No visible wear. I realize that's not much of a test, but I have a 1in Milwaukee M18 Impact, and a 1in to 1/2in adaptor on the way, and we'll see what these sockets are made of. lol I'm mostly kidding. I also ordered a 1inch socket set. Either way, I'm happy with the set. They probably wont see a LOT of use, but when I need them, I have every confidence, they will do what I need them to do. I've already gotten the value of what I spent on them, out of them.

Just great quality

Nice case

For the price, I believe these are a very good value, but after having only a short while, I recommend spraying a light oil on them as they have a tendency to rust.

Superior Design – Flank Gripping – Heavy Duty Sockets – Bargain for this qualityI have a lot of heavy duty “professional mechanics only” name brand sockets like Proto, SnapOn, Mac Tools, and etc. that I have been using for decades to make a lot of money. However, these are “old school” design with sharp angle corners in the 6 point sockets. Of course, a 6 point socket grips much better than a 12 point socket such that a 6 point socket is the go to tool for tight frozen fasteners. This wonderful new design of a 6 point socket has radiused inside socket corners instead of the old school sharp angle corners. Unfortunately, this superior design does not have a rigorously defined name. Some of the names are “side gripping”, “flank gripping”, or simply “radiused inside corner” sockets.A 12 point socket will round over the 6 corners of a stuck fastener making it almost impossible to remove. To save your bacon you then use one of these superior new design radiused inside corner sockets like these to break loose the stuck bolt with the rounded corners. Or better for high torque applications always use this new kind of inside radiused corner socket to NOT round over the fastener corners in the first place.To better explain this superior design, I have attached some drawings to show the twisting torque force being applied to the side flanks of the fastener. The concept is that radiused corners in the socket opening allow the socket inside sides, and not the sharp angle corners, to apply force to a fastener's flat sides, rather than the fastener’s corners to prevent ruined fastener corner Round-Off problems.I sure wish I had a tool box full of these new fangled superior design sockets when I first started out. The sockets do come in a really nice blow molded box with good latches, good hinges, and fitted socket places. However, I organize my sockets inside a big drawer using specialized socket holders of which you can find many different designs from all over Amazon.
