7/16-24 Die

[overkill19]

Anyone have one? It’s a goofy size!

I’m not 100% sure what that means...7/16, 24 threads per inch, I think...but I have a chit ton of taps and di’s from the 40-50-60’s from my gran-dad who was a machinist....I’ll dig in and look tomorrow. Only metric stuff has stumped me over the years!

Hydraulic fitting?

 

[TROLLCAT]

U-bolts ?

You are correct on the 24. As for metric, it’s the size and the pitch of the thread.

Amazon might be your cheaper bet in acquiring a tap with special tpi.

Ya saw one on Amazon, buddy is doing a restoration project. I think it’s a British thread.
No industrial place in Red Deer has one.

It’s what they refer to as 7/16 x 24NS or National Special.
Its not something you will get from Auckland’s, Greggs or the like.
I probably have suppliers that can get it. If it’s a one time use, Amazon. If I have to order it...$$$.

No dice dude. I have some weird ones...7/16-19....but not the one you need.
