Thread cleaning

How about a pipe cleaning tool you use on copper pipe before sweating, or the tool used to clean car battery posts.

I am looking for something I can mount to a motor instead of a hand cleaner. The current set-up uses a die, but that creates problems of its own.

Thanks for the point in the right direction.

that sounds like a car battery terminal cleaner brush

You should use a thread DIE instead.

Brush won't reach all points-EVER.

Hello Sparkman:

do you have a whole lot of studs to clean?

A little lateral thinking.......tried dipping the ends you want cleaning in paint stripper............either acid or 'Nitromors'?

Have you searched for the brush you want on globalspec? They have lots. About 260 companies.

Hello again Sparkman,

try this site. They do lots of brushes for hand and machine use. With a choice of wire thickness. In the US:

Thank you all for the great information. It will take a little while to sort through it all.

Yes, we need to clean a large number of studs. No, any type of solvent would likely cause damage to the paint on the remainder of the part. We have tried using a die, but it sometimes tries to cut new threads or jams on the stud. I am certain that I have seen a brush like this, but can not remember any details. It does resemble the brush used to clean battery terminals and I remember it being similar to a cup-style with the bristles pointing towards the center.

I'm not sure how many " a large number of studs" is, but what I've used in the past to removed paint from threads, and I'm talking 40 years worth of paint, is a tread file. They come in both standard and metric, and each file has 8 different thread pitches on it. I believe you can buy them at almost any place that sells hand tools. Picture of a thread file:

This is an excellent tool not just for removing paint, but if you just need to clean up a nicked thread, and much cheaper than buying a die set.

Hello,

Is this the type of wire brush you were talking of?

I have not used them before and cannot see how they may fit into a drill?

Have included the site address.

Battery brush. Just a tad too big for a M5 stud.

Hello LCAC32:

I just did a search and found this type of brush, where the wire points inwards. I do not know what a M5 Stud looks like size-wise. Just trying to help you know?

When I first saw the search results, it appeared that there was several companies made them and, I figured there may be different sized Battery terminal on Trucks and cars?

I got it wrong....................Take care

Why not chace the threads with the correct M5 thread die?

A 'large number' would be in the hundreds of studs. The current system uses a die to chase the threads. The die is on an auto-reversing arbor, but it sometimes tries to cut new threads and sometimes gets jammed and grabs the stud. Either way, the part is no longer useable. I'm trying to find a safer alternative. It must be motor driven because of the high volume of parts, so hand-operated means are impractical.

Would there be a way to install some sort of plastic cap to the threads before painting? Remove the cap, no paint on threads.

These items come from one of our vendors and adding that step would involve more than the company will care to add to the final cost.

One of the things I like best about this forum is the number of people who can think 'out of the box.' It certainly is refreshing!

How about getting the supplier to dip the threads in that waxy plastic they use to protect tools with before they paint? Something on the lines of this!
