This is a time saver
When I first used this product I was amazed. It made removing the lock nut so much easier. It would be nice if the handle was a little bit longer for a little more leverage for the lock nuts that stick.

Good Spanner Wrench
This is a very well made spanner wrench. It fits my lathe tools perfectly that have a 1/4" hole. But the ordering process on Amazon is confusing. I clicked on 6-piece and at the bottom of the page it shows 6 spanner wrenches of various sizes. So I thought I was getting 6 wrenches. But I now see that the heading at the top of the page says 1 3/4" to 3" spanner wrench which is exactly what I needed. So, I'm satisfied, just confused with their display.

A necessary tool for exploring space
I've been working on my space ship for over a decade and have finally gotten to the hydraulics. This is just the tool I need to tighten up the actuators on the landing gear and the blast shields.

Nice set.
They were pricey but made in USA and the quality is good. I can't complain compared to the chinese junk alternatives I was looking at.

Good tool.
Bought these to remove gland nuts on hydraulic cylinders and they do the job well.

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. :-)

Amazing split/ face spanner wrench
I'm an industrial millwright in the auto manufacturing sector, I use these at work all the time, I knew they were good when I got them but wow!... The other day I had a stubborn gland nut that someone locktighted in, I had a 2 foot wrench extender on my small spanner in the set, then I put a 4 foot cheater bar on top of the extender and then put all my weight i to it...and the spanner was just fine!!! pretty crazy the pins held up with all that force, just amazed, my coworkers

Works very well with my Rohm drill chuck
Works very well with my Rohm drill chuck. Make sure you get O-471A with "A" to make sure that pin is of right size, looks like model without "A" comes with a very tiny pin.

Real thing
Looks and feels like a real thing. It is drop forged so the pin is not going to break off on first use as in cheaper versions.
