Thread Pitch Gauge

[kramarj]

So I need to measure some threads which I believe are metric. I don't have a way to measure them, so I would like to buy a thread pitch gauge, but I have no idea what to buy. I would like the option to measure both metric and standard sized threads with it.

I found this one, am I right in thinking it measures both standard and metric?

Any help would be greatly appreciated.

Yes, that's what you need. "Threads per inch" is "American" and "pitch" is metric. They are easy to use. Most tap & die sets include one too.

That is what I was thinking, but just wanted to verify it. Thank you very much!

You can't use it in every situation but I prefer the style on a chain. Near a Menard's? They have three styles.

If you need to measure really small threads, be sure to buy a quality set from japan, america, england, genrmany.

I use a thread file to measure.

Thanks for that, I didn't even consider a store like Menards to carry something like that. Looks like the local store even has them, I will probably just go that route. Thanks again.

The threads I need to measure are in the 1/2" range, so not small. I usually prefer to buy good tools, but this is the first time I have ever really had a need for it. Maybe someday down the road I will upgrade.

Thanks again for the replies, I really appreciate the feedback.

A good set of Thread Pitch Gauges is a good thing to have.

That being said, metric thread pitch on bolts, especially for M6 and up, is very easy to check with just a small metric ruler (such as a 6'' scale).
1 thread at each mm mark= 1mm pitch
4 threads in 5mm = 1.25mm pitch
2 threads in 3mm = 1.5mm pitch
1 thread in 2 mm = 2mm pitch

metric is MUCH easier than Imperial

I bought a HF tap & die set. It came with 2, a mostly metric thread pitch gauge and an SAE one. I haven't felt the need to upgrade yet, after several years with them. For larger, coarse stuff you're doing, a cheapie will work. $ 10 at Ace Hardware, for example.

"metric is MUCH easier than Imperial"

Really? At least the SAE system is in whole numbers. And measuring for TPI you just count threads per inch, none of the funny divisions.

no neat sig line

Brand recommendations?

REALLY!! you are counting 13, 14 16, 20, 24,,,,,threads over an inch instead of 1 or 2 per mm or 2 in 3mm or 5 in 4mm. I will take metric any day, it is a far better system.

Having used metric for most of my working career I can easily identify the thread and size (and if it is metric or std.) from 3 feet away. I use a 6" scale to measure metric threads as posted above if I am not sure. A thread gauge is good for checking internal threads where a ruler won't fit. Thread gauges should be in every tool box.

You don't need top of the line gauges to get a good reading, Craftsman and similar will work fine at half the price.

Here's where I would get mine if I couldn't get one local.

There you go, cheap and easy.
You don't want to be that guy walking through the big box store holding a bolt in the air saying "I want one just like this".

 

[crguy]

I use a thread file to measure.

WHY? Proper thread gauges are cheap and easy to find.

 

[Tinner]

I have a pair at home and at work. Starrett, Mititutoyo, SPI and General brands. The PEC one linked to above would be fine.

Thanks, that's an awesome method of measuring pitch! It doesn't get any easier than that.

I disagree, using the proper gage is a LOT easier than counting and comparing to a rule.

And besides, you get the added benefit of grasping the concepts of TPI and pitch. This is good info. Don't ignore it.

What about those boards with bolts and nuts on them?

Those would work, although i wouldnt know where to buy one.

I have a Mitutoyo gage for metric, and a General for inch. The Mitutoyo is old, id guess 70s, and is very nice. The General i have about 3 hours of deburring into, because the individual leaves all had burrs.

I would have preferred a Starrett or B&S, but i got a screaming deal on the General for $5 on ebay, and its the big triangular style that has like 50 leaves.

Where are those made?
Why does the Inch model cost twice as much as the Metric?

$10 would be the about the max I would want to pay.

Thank you for the link. I might purchase a couple if they aren't chi-chi and are accurate.

Cost difference: the basic inch one has blades for 52 different threads, the metric 24. It states "Made in Germany. Model 44D .... premium USA model made by PEC Tools."

Lee Valley used to carry a nice looking one they called Thread ID, although it was limited to smaller (M6 and 1/4") thread sizes:

Edit: McMaster-Carr sells the larger type you usually see in the hardware isle of big box stores; #20375A27.

I don't think you converted your fractions properly when you bought the drugs you are smoking.

 

[OkRider]

Starrett.

This^^^^^or Mitutoyo.

That sounds so harsh. A simple 'are you high?' usually won't offend!

I found this one for a buck at a local pawn shop recently. Thing is absolutely fantastic. Wish I could figure out who made and buy some more.

That is really awesome and compact too.
