Metric Thread Gauge

[gerryr]

I'm embarking on a quest to eliminate a lot of the metal parts and threaded inserts from my fountain pens and rollerballs. In order to do that I have to figure out what the metric threads are. Does anyone know where I can get a metric thread gauge?

They have metric ones also

Most pen threads are .75 but there are some variances

Gerry, I have one if you want to use it.

The problem you may run into is that a lot of the threads on pens are proprietary threads and not just standard metric threads. The other problem is that many of the pen threads are multi-lead threads rather than just a simple single lead thread. You might want to chat with Rich kleinhenz (Scubaman) by email as he is probably better informed about pen threading than most.

I'm only really concerned about the nib holder threads. I'm not looking to duplicate the cap threads.

Then for the larger pens it a .75 thread. There are no proprietary threads in pen kits.

Can you tell me the diameter for the El Grande also?

Here are some snippets stolen from posts on this site over the past couple of years. Most of them come from Anthony "PenWorks" Turchetta.

I tapped the inside of the pen barrel to hold the nib.
It is an El Grande nib, threads are 10x1.00 metric.

most of the threads on the Jr/Baron, El Grande/ Ligero and others are EE & EEE, which means it has several starting points. I don not believe we can hand cut threads for that. But that would be a question for Bruce or any other tool & die makers lurking around here. The only regular type threads on the pens we buy are found only in the nib section and in the trim end caps.

gents pen…The threads on this were US fine threads, I'm at the office so I can't remeber, but I think it was 9/16/ x 18

Cool. I remember reading that and I think I even wrote that size down --- someplace.[]

If you want to come and visit, we can find one at a local hardware store, auto store and home center. [] []

Here is a photo of the El Grande (black) and Gentleman nib (silver). The Gentleman is .75 and the El Grande 1.0

To simply answer your question: any hardware store.
