Questions & Answers
I'm not sure why I got this question since I bought the 18 mm, but the 18 mm has a 28 mm outside diameter.
If you're working in a tight space, you might want to avoid using an impact socket. The walls of impact sockets are typically thicker than those of hex sockets.
For coarse pitch (1.25 inch), the hex head diameter of M12 is usually 18 OR 19 mm. I'm not sure which one would be the most likely for 1. "Plug nut" with a pitch of 5 mm.
Hello, Barry G, and thank you for contacting us with your inquiry. A 19MM lug nut can be tightened with the CMMT15867.

This was purchased to replace a socket in my original set that had gone missing. These sockets aren't as good as the original Craftsman sockets from a few years ago. Instead of being made in the United States like the originals, this one is made in China. That's not necessarily a bad thing, because almost everything these days is made overseas, but the socket's finish and cut are far inferior to the originals. I'm hoping it lasts as long as the originals, which I've had for over 15 years.
I'm not a professional, so I didn't use an impact driver with this item. I needed a 6-point 17-mm socket to change a serpentine belt. For some reason, the only impact options are 6pt or 3/4, which didn't help me because my breaker bar is 1/2. It met my requirements and appears to be of sufficient durability. It's also a plus that the item is made in Taiwan rather than China.
I was initially disappointed because I already own a polished and attractive 21 and 22 from Lowes. Then I got my 24 from here, which had a flat powdery finish and clearly different fonts. I decided to make a comparison. Made in Taiwan is written on the 24 from here. Made in China, according to the ones I bought from Lowes. Taiwanese tools, in my opinion, are superior to Chinese tools. So it's possible that I struck it rich. Others have stated that theirs say China, so I'm not sure. If the tool is of higher quality, I won't complain about the flat black look.
My impact wrench would not budge the 17 mm stainless bolt corrosion welded into aluminum, so I can't say it's an impact socket. All it took was a little heat and a 24-inch extension bar to get the job done. A socket made of vanadium steel would have been fractured by the forces involved.
This socket has a true impact. Impact-rated sockets are sometimes marketed as glossy black sockets that aren't. This socket has a wall thickness that is roughly twice that of my standard 1/2 drive 6pt sockets. However, it lacks the strength of my tool truck set. 18 mm sockets, on the other hand, aren't used all that often.
I needed to remove a frozen bolt, but my chrome coated standard socket broke, stripping the outside of the bolt, and I couldn't get a grip on it with another standard socket. This socket had a perfect tight grip when I got it, and the bolt came out easily.
When you only need one size, it's a good deal. I bought this 18mm for my Chevy Silverado's brake calipers. These are usually so tight that you'll need a 1/2" breaker bar to get them open. For this job, a 1/2" impact-ready socket will suffice.
He managed to pull it off, to be sure! I saved hundreds of dollars by not having it serviced!.
