Hey guys, looking for someone out there in sawdust land that might be able to shed some light on a front/face vise that came with a really nice workbench I bought at an auction recently. Have always planned to build a nice bench, even had drawn up plans what I wanted and everything, then along came the auction and I was the successful bidder at only $120. The vises alone would have cost that much. It is a traditional Klausz style bench made of white oak but it has drawers on one side along with a tail vise and front/face vise on the left.

Here is my only problem…..............the front/face vise does not have a nut to accept the Acme threaded center screw and I’m having a hell of a time finding a nut here in central PA. I checked with Fastenal and they had a 1 and 1/8” nut that was 5 threads per inch. The diameter was right, the nut threaded on the tip but wouldn’t advance.

There is no name on the vise, simply some numbers and “USA”. I imagine it is from the ‘60s or ‘70s. It is similar in design with the modern Chiwanese jobs you see at Rockler and Woodcraft, Groz 7 and Grizzly both have similar looking vises as well. It is cobalt blue, matches the tail vise, looks to be the same manufacturer.

Anybody have any thoughts who the mfr might have been as well as what size nut this takes?

Thanks for your help guys!

McMaster Carr carries flange nuts for Acme thread. They are spendy.

Measure the threads per inch and the “pitch” or angle top to bottom of the threads.
+1 on McMaster Carr.

Thanks for the tips, guys. I heard about McMaster Carr but hadn’t checked them out yet, assumed they were similar to Fastenal. I printed out the template from the Acme thread website and it looked to match up to a 5 thread per inch, yet it didn’t go. I saw some references made to Acme thread for vises that might be left hand threads – something that never crossed my mind. May see if I can find a local machine shop that can at least identify what it is so I can order from McM-C.

Any thoughts on how common left hand threads may have been on older vises?

Update on search for Acme threaded nut…..............the 1 and 1/8” and 5 threads per inch, right hand threads, is correct, however the threads on my vise screw are deeper than a standard acme nut this size, thus the reason it screwed on but would not advance. I called McMaster-Carr and they only have the same standard acme nut like Fastenal had. While there are different variations of acme nuts for 1” and 1 and 1/4”, the only thing I can find in 1 and 1/8” is 5 threads per inch, basically what I already tried.

Any more ideas before I take it to a machine shop to have something cut?

Thanks to all for your $.02

I am racking my brain to try and remember, about 3 years ago I had to replace the slip nut on a wood vise at the shop, it to is that old and has no identifying name brand but it is actually a popular vise that now days, they tell you they made them. The nut is brass if I remember correctly and dangit, I just can’t remember who makes them, I think the nut was like 6 bucks with shipping though…. I will try and remember

Try this, the mechanisms should be the same…. maybe if not then look around the site and see if they make comparable parts.

If you can not get a nut for the acme rod, it might be possible to replace the rod with a new acme rod and
use the matching nut, but the expense might not be worth it, or possibly you could get a machinist to make
a nut for you if you took the rod into them for matching purposes.

Appreciate for the help guys. TCC, will check out that site you listed as well as try to post a photo or two over the weekend. never thought about the idea of trying to replace the screw itself, someone at work suggested that as a possible option as well.

Thanks again all, Andy

Here are some pictures of the vise. Bluepine, I like the possibility of seeing if I can switch out the Acme threaded rod, may be simpler than finding an oddball depth nut. I have an ancient Richards-Wilcox vise that has a threaded collar that fits between the front and back center hole; this vise probably had something similar, not sure how it disappeared from the previous owner??

Appreciate everyone’s ideas. Andy

I need to chat with you regarding your vise issue. I’m in nearly the same situation, and have been looking for weeks for some information about my mysterious no-name vise. I’m attaching a photo of the part which I’m searching for, and also need the nuts for the acme thread lead screw.

Your response would be appreciated. Thanks in advance.

“The diameter was right, the nut threaded on the tip but wouldn’t advance.”

It is possible that the screw is a double lead, makes the vise rapid acting on open and close.
That can be seen looking at the end of the screw, there will be two grooves 180 apart, rather then just one groove.

Hi guys, apologize for not updating my situation. I work in Human Resources and was at an open house at a local vo-tech school where I was introduced to the head of the machine shop technology program. I told him of my situation and he told me to bring it in so I brought the vise screw and the underside piece that was in my photos….....missing whatever was originally in between the north and south holes to accept the vise screw. Well after having it for 3 months, I picked up the finished product at the Employer Advisory Banquet a few weeks ago. What they basically did was machine a cylinder – probably 2.5” OD – to accept the acme screw and it sits between the holes – is free floating – not welded or fastened in any way. Works like new, nice to have a working face vise on my new workbench to go with the tail vise!

Also, the instructor originally thought it was a double start thread but told me when it was finished that it was not. The end of the screw needed a little work but the screw was NOT double start. Still have no idea who the manufacturer is but my underside receiving plate looks a lot like the photo Cey posted.

Happy holidays LJ guys!
