Very study and works well! No complaints!

This 3/8' square drive female to female socket is very well made. I'm sure it would withstand impact drive and will last a long time.I use this for calibrating my click-type torque wrench with a beam-type torque wrench which is much more reliable but harder to use in confined spaces. Works great for my use case.

Needed one this size for unscrewing old fashion bed bolts (square head). Difficult to find this size without buying a full set. Great price for a single unit, which will be used very very infrequently. So cost was a factor.

As described

These work really good for tightening beam clamps to I beams with either a ratchet or impact (carefully).

Works great. Got my new socket today love it.

Used for removing oil drain plugs on small engines. Works great! I don't have to use pliers anymore.

This tool has 3/8" female square-holes on both ends.There is a circular hole all the way through both ends (I imagine this is to relieve air pressure, to aid in attachment).My use was to create a Double-Female-Ended socket extension (See photo).One ends 3/8" hole has a relief-detent on the inside edge to make it easier for the ball-bearing-lock to enter and engage. This is a tight tolerance hole and fit! The other end is a normal socket set type easy fit.Know the difference.Installing it on the tight-fit ball-bearing attachment end was not a hand fit! I had to use a light tap with a hammer on the other end to engage and seat it on the extension. The connection is solid and it will not be easily removed. It will probably take a slight hammer tap to remove it from this end. My use is permanent, so I am happy with this design.The end with the detent is tight, by design I think, so it will never easily fall off. The other end is a normal hand installed 3/8" socket connector. Easily added to and removed like normal socket ends.I have only one reservation. My use is light duty. I have not tried it with an impact wrench in hard daily use. It appears to be a stout and strong unit. But I make no claims or knowledge for tough usage.This is a well thought out, engineered and executed tool. I fully recommend it.

Much easier to loosen and tighten garage door spring set screw.

I have used snap on and matcos magnetic sockets. The GP is way better and is deeper than both.

I had been looking for one of those a while a I found it here and I was able to buy a sat or only the one i needed

Good construction and useable on built-on water faucet valves. Four sided sockets are unusual.

Good quality

Great socket study and the magnet does clasped up and down.

This is a fantastic product well made and fits perfectly for my application. I am a commercial garbage door service and Installation technician; this particular socket fits the set screws on the spring line perfectly. Thank you this has made my job easier

I work on garage doors and this socket is awesome for the set screws

I use this for the square bolt on my garage door spring. No issues.

Worked great

Another specialty tool but it’s convenient to have

It does what I need
