Title: Metric thread file
Post by: coolford on May 21, 2019, 02:31:17 PM
Some time ago I bought a box lot with two sae thread files and have used them many times.  This metric thread file showed up in another box lot and was made by Con  Val in the good old USA.  Don't know how I got along without thread files in the past.

I've never quite gotten the hang of thread files.  I don't know what I'm doing wrong, but they never seem adequate to the task.

I use them a fair amount at work (machinist). They are just the ticket for taking the burrs and sharp edges off after you cut a key slot in a threaded shaft.

I like the ones i got from JAWCo and they, too, are made in US.   Good folks to deal with, also.   :smiley:

I've got a set of Snap-On thread files. Set had 2 sae and 1 metric, got them in the early 80s and can't fathom how many times I have used them.

I'm with you, Bill. I've got a pair of thread files but rarely use them as they don't seem to do much.

Maybe it's my wrist angle?

They can't fix stripped off threads but do work well!

Just used one to clean up threads on a very oddly sized screw on some toolmaker's clamps - the size didn't fit any conventional machine screw or SAE sizes, but it was not metric.  I think I may have finally gotten the rhythm of using one.

Hello, i have had good results with the larger, coarse thread sizes. Fine threads and smaller diameters are tricky!! Regards, Lou

If I have a problem getting a thread file to work I use a file to get it started and then they usually work well for me. It was something that I did have to practice with more than I thought I would have to do. It looks like it should be easy.

I start them on good threads and working down lightly then more pressure as the thread improves

oldgoaly I will try that as well.

When you start at the good thread it means you are only trying to clean up one thread at a time. The good threads guide you, not going to save every bolt but will save a few.
