Mr. Corona –
They are Klein
I have not used but they obviously work phenomenally great. I liked how small they are and are space savers in the tools pouch
Alex –
Great
Great tool

These get in the tight places in a box.
The offset comes in real handy in small boxes. One end is for tightening and the other for loosening. It’s a little tricky keeping it on the nut. Because of the offset, the wrench tends to want to roll off. It takes a couple tries to get the technique down, but once you get the hang of it, they work well. Each wrench has a couple small embedded magnets in the handle area. All three stick together in your tool box. The different colors help when grabbing one.

Good tool
Work like a charm. If you are running conduit on a regular basis, come in real handy.
D.R. Briggs –
Great package
Slim design allows for use in tight area, magnets keeps wrenches together for convenient storage.
Ethan Baird –
Meh
Looks cooler than it actually is. Itâs hard to keep the tool on the lock ring
dbaylor –
Time saver
Works perfectly can get a ton of leverage
DHLE –
Very helpful tool!
Nice tool to be used in limited space.First time I used this wrench and have a kick out of it.The tools are sticked together with magnet, a good feature.I now buy a $250 veto backpack to keep them, along with other tools.Highly recommended!
Dave –
These are more expensive, but when you hold them in your hand you’ll understand why. They are beefy and thick, with magnets that hold the three aligned together for easy storage. They maintain the Klein reputation of being first class tools that will survive a lifetime. The only thing missing is the offset that some manufacturers offer for getting into recessed spaces.

These specific jam nut wrenchâs work so much better than water pump pliers or whatever you have been useingHandy . Stay together with magnets and good tooling so they fit well

Considering that I’ve been doing electrical work for years I can’t believe I didn’t know these tools existed. I’ve been able to get by just fine but this is so much easier and better and a great addition to my tool bag. Not cheap but I don’t anticipate ever replacing them so over time probably good value.
