Williams JHWO-471A Adjustable Pin Spanner Wrench with Span Diameter of 3/4 to 2-Inch, Ideal for Adjusting Collars, Lock Nut Rings, and Bearings

Great tool, held up to some stuck components, had to abuse it a bit by beating on it and using a cheater

It does the job it was designed to do. What more could you want?

Williams adjustable pin spanner wrench seems to be a high-quality tool. The only improvement would be to have a longer handle for more leverage, but other than that it will get the job done.

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.

Very nice spanner wrench. I got this to see if it would work on the dimpled receiver extension nut (castle nut) that Knights Armament Co. is now using to secure the receiver extension/ buffer tube and end plate to the AR lower receiver. It was a tight fit, but I was able to work the pin into the dimples and wrench the nut securely in place. It did not mar the finish or leave any marks. Brownells makes a nice tool for the job which also includes a socket for a torque wrench. But if you want something a little cheaper this is a nice alternative and it works. It's a durable quality tool as well.

Excellent manufacturing and top notch quality, which mandates a price that might be unreasonable for someone who doesn't appreciate USA-made tools. For me, the barometer is the price of gasoline. If the difference in cost between a USA tool and a cheapy import is less than a couple of gallons of gas, it's a no-brainer - I buy American. If more than that, I borrow or rent the tool, if possible. This wrench performs perfectly and is definitely a keeper. I use it in servicing concrete vibrator flex shafts.

This Williams scanner tool broke immediately upon trying to unscrew a rack and pinion collar, I purchased this more expensive tool for Williams tools because I thought it would be better quality than the cheaper competitors version! WRONG it broke immediately, and the customer service after a month of waiting on a replacement says you can’t use force on their tool so it was my fault? Unbelievable response from the worst company I have dealt with in a long time. My collar loosened easily with a small pipe wrench I just wanted this tool to not have pipe wrench marks on the collar. So buyer beware these tools are complete junk and they won’t stand behind their product if there is a problem.

Extremely good quality!

This order was completed very well.

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.

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.

Seems to be good value. Does what its intended to do.

Good quality. Delivery date took a while but it did eventually arrive and works perfectly.
