Was in the machine shop this morning and took a couple pics as promised.
Snap on makes a huge range of SAE 3/8” 12 pts. The big 3/8” one is 1”. Not sure if the 1/4” goes up to 5/8”. I use the 9/16” often, but not sure about 5/8”. As I said, none of these are impact sockets they are “G code” non-impact sockets.
The extensions are a mixed bag of 1/4” and 3/8”. I found that tray on eBay, and whatever I paid for it was too much, but I like these sorts of organizers, especially for extensions and especially for black ones.
Quick story, before I started where I work, a mechanic left an Allen wrench in a bolt head in an aircraft transmission. He just missed it. So did the quality inspector and probably a half dozen other mechanics. That aircraft came down pretty quickly, killing its crew. Allen wrenches are HARD. Keep track of your tools!

Here’s the wrench drawer if anyone is interested. This shop will probably maintain any heavy equipment I buy in the future (currently shopping for a skid steer). So the big sizes are helpful. Some have already come in handy. Most of my work so far has generally stopped at 15/16”.
For our UK friends, we call the hinging tools “spanners”. The non- hinged tools “wrenches”. Shown are “pin spanners”, “hook spanners” and “face spanners”. These are essential for many industrial applications, but I have them specifically for joints on my bridgeport milling machine. Not sure what these would be called in the UK, but I’ve heard people say we don’t use the term “Spanner“ here in the US and that’s not true. If anyone was interested in what those tools are, that’s what we call them and why I have them.
I gave these tools a quick wipe down with oil before I took the picture. Worth mentioning, you really have to routinely oil or protect these black oxide tools somehow. And regular reapplication is a must. Even the screwdrivers are black oxide. BTW, some of their handles were absolutely black during the Bridgeport rebuild. Horrible. They clean up fine. They almost look new in the picture and they absolutely are not!
Last, you can see how well my white crayon trick holds up. That was one of my first posts on garagejournal probably 10 years ago! I didnt do these wrenches 10 years ago, but it’s been several years. It holds up and it helps!
