Anyone have the thread size for the tang screw for an original marlin 1894 circa 1902?
Any help would be appreciated.

I believe all used the same screw, it is 12x32. Try a 336 screw.
I am not sure of the early ones but later 1894's were built on 336 actions.
Do you want the info for the Tang Screw or a tang sight screw? I think the 8-40 is the sight screw size OK but the actual tang screw is prob'ly a 12 something. I can measure one for you if you'd like. Regards, Woody

I Have a Marlin 1984 made in 1901 , I could pull the screw but wouldn't know how to determine the size .
how would I do that,?.
i.m just sitting here watching the wheels go round and round..... i really love to watch them roll ,,,, J,W,L.
Hey there downwind -- Marlin tang screws are a .210x32 proprietary gun thread.
Marlin 1894's have always been and were NEVER built on anything but an 1894 frame. The 1893, '93, 36, and 336 were a complete different animal.

What does the 2.10 part of the 2.10-32 thread size mean? (not trying to be a smart >>>)

For anyone following this thread, check out this from a couple years back.

It's actually .210-32 NF2 and I believe the .210 is one of the diameters.

Yea, if it is a decimal or 5/16" it is straight forward. As written, "2.10" was a foreign system to me.
Thanks.
5/16-32

Hey there Chill Wills -- Hadn't realized I misplaced my decimal point!! Or maybe it just got out under the back fence... Got'r fixed. Best regards. Wind

.210" is the OD of threads and is almost a 12-32 or exactly as a 12-28 has a .212" OD. It varies and my 336 tang screw is .2075". Usually a 32 thread will have a smaller OD then a 28 but not always.
The Major diameter of a no. 12 is .216" so even though the 336 has a 12-32 thread, it does not seem to match.
You can see the differences.
The basic effective diameter for a no. 12 is .1928" so how do you class a .210"? A .2075" or a .216"? Now WW 94's have a .205 X 28 tang screw and it fits no place. It is not a 10 or a 12.
I do not have a 12-32 tap so I can only go out on a limb to say the 336 tang screw will fit after seeing so many size differences.
My 1960 encyclopedia of modern firearms calls for a 12-32.
Here's a link to an article with a significant discussion of Marlin screw sizes.

I read the link and strange a learned man does does not understand a die. there is a start side and it tapers. so if you need a thread to a stop, you reverse the die and cut from the other side. Threads cut with a die are smaller at the end.
Want a crazy screw? front band screw is .330 X 42.
But the read was very good with all the strange screws used.
You can see all the problems with old guns. There were no standards at all.
I get out of sorts and change threads to fit what I have or can make.
The top of the V form thread has a flat on it. Not even a 100% fit comes to a sharp point on the top. When you measure a correctly cut thread you will get a +/-, +=zero, -< stated and that always accounts for the slighter smaller measured diameter when you mic a thread. A 75% thread fit is a good fit.
Again, not trying to be a smart .....

Even today we have crazy stuff. What is the thread on a shotgun rod jag? I believe it is 27 TPI. WHY?
I gave up and made my own rods and jags for shotguns. No slotted ends.
Old timers making long rifles filed threads to make a tap and a screw to fit. No tap and die sets so they were all over the place. They cut a cherry to make a mold by hand to fit the gun.
It took a long time for standards to come in. How in the world did they measure so close?
