Hi all.
I need a set of SAE thread chasers, cheap is preferred; 1/4-20" and smaller. (I have a storage rack and am bolting "J-hooks" onto it, but need to shorten the bolts and clean up the threads so the bolts aren't over length.) In setting up to move I cannot get at the tap and die set - Oops.
Thanks!
This may be to shade tree for you , but I just run a nut on them before cutting then clean up the cut with a file , cut off wheel or belt sander then back the nut off works fine for me 99.9% of the time.
This is what I usually do too. Over the years I've accumulated many taps & dies though. If you want a cheap set of SAE taps & dies check out Harbor Freight. I don't like their stuff but many people use them, I'd trust the dies over the taps. https://www.harborfreight.com/Carbon...-Pc-62831.htmlQuote:

Small Tools Inc. located in Euclid, OH. I've found taps and dies from 0-80 to over an inch, they have metric as well some Whitworth and BSF. New and used. Call them and tell them what your looking for. The owner is Bill, he or his wife will answer the phone
Couple of different places..

Many of the lesser expensive electrical crimping tools have thread chasers on them. Most I have seen are machine screw sizes like #'s 6,8,10 and 12. You screw the screw into it, cut it off and back it out.
A nut would do it for me for this probably, the plan is to cut the bolts shorter then thread lock the acorn nuts on (otherwise my hands get cut up a lot when reaching past these; I'd been using nylon wire ties but the J hooks are heavily loaded at times so they were stretching / breaking too often.)
So a nut would clean the threads up "well enough" to get the acorn nuts on.
I'll look at the other places too, thanks all!
I ussually cut and chamfer with a gile. running a nut down first. Use a fine blde in the hacksaw like 32 tpi
file instead of gile? (Typos happen!) I probably will use a cutoff wheel in the rotary tool.
Sorry my keyboard is getting old ( like the user). The cut off wheel will work then a mounted point and chamfer end. If the studs arent to long chuck inn drill motor and spin to cut chamfer. I have done it all with the cut off wheel. Chuck in lathe cut chamfer first to dept the square wheel and cut off. this gives a solid surface for the wheel and keeps threads from pulling the cut. Makes a very professional job
Run 2 nuts on, then tighten against each other to lock where you want to cut. Much easier. Then clean up, taper with the file.
Everybody needs a set of those square thread files. I reach for them before I get out the die set. They are really good at restoring threads that have been damaged or bumped or rusted. When you live on a farm with some old equipment the files are a must.
Yep and they pack lighter than a full set of dies. I've got 2 that cover 16 pitches.Quote:

It must be the same set of thread files I have also. And they work very well as thread gauges too to figure out how many threads per inch an unknown bolt has. That and a bolt diameter gauge determine all you need to go purchase a new bolt when needed.Quote:

Most hardware stores carry bolts of various lengths in most diameters.

Did you try the Internet for vendors? https://www.google.com/search?q=thre...=firefox-b-1-m
See if you can borrow a die from a friend. You still might need to touch up where it was cut off.
[smilie=s: Might give Fastenal a try also.
Good luck.Have fun.Be safe.
