Metric thread file

[bulletpruf]

Fellas -

I like using original fasteners when I can on my vintage cars. I recently ordered the Sears Thread Restorer Kit from the hot deals thread - http://www.garagejournal.com/forum/showthread.php?t=238616

Thinking I should still pick up the Nicholson 4 file set -- http://www.amazon.com/dp/B00MNRXFZK/?tag=atomicindus08-20

Have to admit that I'm confused on one thing -- I'm used to seeing two types of SAE fasteners on my U.S. made classic cars -- fine and coarse. Are there two more flavors? Extra fine and extra coarse? What applications use these?

FYI - here's the comparison in the thread files in the two sets above.

NICHOLSON: Type 1 black cap: Regular bolt; 11-12, 13-14, 16-18, 20-24 TPI
CRAFTSMAN: 11, 12, 13, 14, 16, 18, 20, 24

NICHOLSON: Type 2 red cap: Ex. Fine/ex. Coarse bolt; 9-10, 12-16, 20-27, 28-32 TPI

NICHOLSON: Type 7 green cap: Regular pipe; 8-10, 11-1/2-14, 16-18, 24-27 TPI

NICHOLSON: Type 8 blue cap: Metric Bolt;. 75-1.0, 1.25-1.5, 1.75-2.0, 2.5-3.0.
CRAFTSMAN: 0.75mm, 1.00mm, 1.25mm, 1.50mm, 1.75mm, 2.00mm, 2.50mm, 3.00mm

Thanks,

Scott

I have 5 of them 3 metric and two SAE. The other day I was at the Sears store looking for decent buys. They had two sets on the hanging pegs on the wall. Your local Sears may have them too. Steve's wholesale tools in Oklahoma City also has them in stock.

I'm about 7,000 miles from the nearest Sears...need to find something I can order online.

Thanks

Snap on also has some similar files for about the same price.

You can buy everything in singles for decent/fair prices if you need replacements.

I think that one may be NPT and/or some other pipe fitting threads.

Maybe someone who is an expert on that can chime in?

The best bang for the buck is to get the Craftsman 48pc thread restorer kit that comes with 2 thread restoring files, and then also purchase a Jawco #3 thread file. The Jawco #3 includes all the sizes that the Craftsman set skips, and you don't end up needing a 4th file just to get a complete set because of all the size duplication (like the Nicholson set). The ones shown in bold lettering are missing from the Craftsman set, notice how only the 20 size is a duplicate. Do it this way and you are all US made, you also end up with a comprehensive set of thread dies in SAE and metric, and if you wait for good pricing at Sears you are only out $50 total for everything.

Jawco #3 - 8,9,10,11-1/2,20,27,28,32

I have a set of 3 as well 2 are SAE and one is metric. I have had them for many years 20+ and they are great at cleaning up external threads.

I also have had the three thread files for decades; but only recently bought a thread-restoring tap/die/file set.

I got the Kastar/Lang 971 "48 piece" "Master" rethreading set. Truth is, it should be a 49-piece set as there's only one SAE and the one Metric thread file. I therefore have duplicates of two out of three thread files.

Thanks, Jeremy and Schurkey. I bought the Craftsman thread restorer kit that I found on the Hot Deals thread here -- it was $37 or so. Money well spent.

I'll pick up one of the Jawco #3 thread files to complete the kit.

I have an older Blue-Point axle chaser that is hinged and will clamp on behind the damaged end of the axle. Then, you can just unscrew it and it will straighten out the damage as it comes off.

Thread files are great on some repairs but some may require a good file. A triangle file has the proper 60* angle to file a thread that may need a bit more attention than a thread file can do. I find that I'll grab a triangle file more often than a thread file to adjust a damaged thread, especially the first thread on the fastener.

Thanks, Larry. Have a few triangle files, but am about to upgrade my file collection. Hope Santa leaves some nice ones in my stocking.

Not sure if this has been thrown out there, but I have it and for the price it cannot be beat!
