It just goes to show the right tool makes every job easy. Construction of the wrench is impeccable
Spectacular. I had to remove the top nut/cap nut ( 24040 ) on a 50's era Hein-Werner floor jack to put in new seals. It would not budge with a huge pipe wrench and a cheater bar - it was just chewing up the (very hard to replace) top nut. I clamped the hydraulic unit to my workbench, put this Williams 474 adjustable hook spanner wrench to the nut, along with a 2.5 foot pipe cheater bar, and had it off in 30 seconds.Incredible. I thought for sure I was in trouble with this nut. The torque specs for the nut are insane - hundreds of pounds of torque were put on it when it was put into place - about 60 years ago. It just goes to show the right tool makes every job easy.Construction of the wrench is impeccable, no slop. It comes in a non-slip, functional steampunk black oxide finish. From where I am sitting, with the nut off, it is absolutely beautiful. :-)

Works good, great price!
I feel this was a good value. I own mostly snap on tools so I bought this knowing that williams, and Armstrong are sister companies to snap on. The finish was decent, not quite top quality but decent. Works and performs well. My real complaint was in the casting of the tool, there was a sharp edge on the handle that was not cleaned up. Not sharp enough to cut yourself but enough to be uncomfortable without a glove. Kinda Harbour freight quality. Not sure if all are like that or just the one I got. Overall I'm happy with purchase. It is a spanner wrench so it's not used everyday but I do use it where I work regularly. How this helps

So much better than channel locks
I use this to tighten conduit lock rings. It has made life much better than using channel locks.

Durable and works great.
This pin spanner wrench is just what I needed, and looks just like the photo.I have an old lathe where this tool was recommended to remove an adjustment mechanism. They used this tool back then for many pieces of equipment, but not on my particular lathe. However, I tried two different kinds of strap wrenches to no avail. When this tool arrived, I drilled a shallow hole in the mechanism to accommodate the pin in the tool. With very little force, this tool removed the mechanism perfectly. See the photos I posted.The pin seems to be very strong. The pin is 1/8" diam and 1/8" tall.It comes coated with a corrosion preventive substance that has the consistency of light weight oil.This was worth the purchase. Now I can get back to refurbishing my 1937 lathe.
