The Thread Thread - Tap and Die Sizes.

[Sanchito]

Theres one of these on PBN, and its very helpful information for those who love to build guns and work on them, but like most other threads on PBN, its been just about ruined by clutter and whatnot.

For the above link, I recommend reading the Patents section. It explains alot and some new stuff not even on the market.

[Sanchito]

i know alot of you uys know automag thread sizes. PM me, and ill add what you know to the list. as you can see, the automag tab is a little empty.

If you know any other threading sizes, that are not on the list, PM me and ill add it.

[Sanchito]

thanks to P8nt for the automag section.

[trigger090]

so i have a funny story about threads being tapped.

I broke a head off of a screw and i was tightening the asa on and so i didnt know what to do so i took it to my local hardware store who has helped me out in the past and it just happens to be an ACE you know the helpful place and well he drilled the screw out and the next day i came in to pick it up he said that he had to tap the threads and i said ok and watched him do it and all of a sudden the guy says "wow this seems really tight" and then i heard a snap and yes he broke the tap just like i broke off the screw and then he went to drill that out and broke the drill bit off inside the hole so thats where i am right now its still down at ACE hes trying to figure out how to get it out with out damaging my inteli more that he already has any suggestions???

[Hilltop Customs]

Take it to someone who knows what they are doing. I'll admit ive broken quiet a few taps, but if he was just cleaning some threads with the tap and broke it off, hes definitely doing something wrong.

Bump

For those just needing to know
I sure did.

Edit: I'm getting conficting drill bit sizes. What final drill bit size do you need for drilling the ASA 1/8 NPT 27. Is it 11/32, 3/8, 21/64 or?

[pinkanese]

ooh i should probably add my list of all the screw sizes for my mags tha i came up with, will be helpful. Just need to remember to get it next time i go home.

[questionful]

I have a question to bump this up with.

You know this barrel:




Well, the stainless tip is threaded on there. I took it off of mine. I want to know what the threads are at the tip of the barrel, so that maybe I can come up with some neat stuff to put at the end of my barrel.

[Ando]

Find yourself a Pitch Gauge (I think that's what they're called )

[questionful]

Yeah I go to a machine shop tomorrow (I'm taking a machining class) so I'll take the barrel and do some measurements on the threads.

[questionful]

Can anyone help me figure out what thread this is.

I measured the major diameter, it was .811" but i'm not sure how accurate I was. I think fairly accurate.
I used a pitch gauge and found it to be 32 tpi.
I used a metric pitch gauge and found it to be .80

What do I do now?

51 / 64 = 0.796875
52 / 64 = 0.8125

.811 inches = 20.5994 millimeters
20.5 millimeters = 0.807086614 inches

I doubt I can get my hands on a tap for this thread so I guess I'll just have to cut it on a lathe if I want to make a raincover. If I do, I'll be sure to make several pieces for anyone else who would be interested.
