rail on a 336 receiver..gun hardware? wtf...need screws

Post by dieselbeef » Sat May 04, 2013 8:27 pm

so im putting together a 3030 336 for a ranch weapon. mt'd a flashlight...werkin on the action...bah bah..etc

heres my snag tho...i got a picatinnny..weaver ..whatever mt for the top of the receiver. i bought it off ebay and the mt itself is decent for 8 bucks...
i wanted the egw or the grizzley setup but naturally theyre out of stock,,,

so herein lies the problem. the screws that come with it are too long. they get tight in the btm of the hole like its not threaded far enough. the holes go all the way thru but they wont screw all the way thru. and on top of all that they are just too long. when they get tightened up they jam the action cuz they go thru too far.

so wtf is the deal with gun screws..are they some kind of special thread..cuz they aint metric and they ain standard..

and i need some .050 shorter than the ones that came with it. i tried to modify 2 of them but it is just a pita since there so small..i need the right ones...

good local shop to get the right screws...going to jm gun repair since theyre real close unless ya got someone is sarasota is better.
im the other gary...

Yep. Guns, especially scope mounts, sights, etc use some very unique threads. I have an assortment I bought from Brownells just for this very reason. I quick stop at your local 'smith is most likely required unless you know what size you need.

Can't just file off .050?
If you are near Crowder's at LWR and SR70 they have just about everything you could need in the way of fasteners.

They are probably 6/48 or could possibly be 8/32.....
Got any more info in the size versus how much you need to cut off ?? I have a bunch at home, but I'm out of town right now

The Crowders I use most is on Manatee W. They have EVERYTHING.
Never once have I stumped them on a fastener, gun related or otherwise.
I even carried a rifle in there once to test fit a screw.
(Yes Rent, test fit a "screw", right there in aisle 14.)

no ive got samples tho. they dont seem like standard thread to me. ive got fasteners like crazy here at werk and im not sure of the size..but ill get to it before i go hone...maybe ill get lucky

i was wondering if theywere a special gun only kinda thread size or pitch..if yall say theyre standard then ill get a tap and see. they might be once im done anyways [smilie=012.gif]

well..either the bolt aint the right thread or .....it doesnt fit our thread guages here. it seems like it has a 8x? 32 isnt fine enough and 40 looks too fine
ill try crowders tho...if not i got some washers to put under the mt..but i really didnt wanna do it this way. im afraid that if i tighten it too much and break the screw or strip the hole because the sizes aint right im really gonna have a problem. it seems like it starts in but doesnt go in far enough. as tho it btms out but the hole has no btm..so i say the pitch is wrong...

Just for the heck of it, I did a Bing. Here's the easiest answer.
What size screw fits in a rifle scope mount hole?

Answer:
The industry standard for scope mounts is the 6-48 screw. This is an oddball size due to the fact that it is only used for that application. Brownells is one source for such screws and related tooling. Larger magnum builders have opted for the 8-40 size, however, to stand up better to the rigors of the magnum recoil.

You can successfully shorten the screw you have, if you can find a nut of the same thread pitch.
Run the nut up past where it needs to be shortened.
Shorten the screws on a good grinder.
Then back the nut off to fix the threads that are messed up.
Usually works like a charm.
If all else fails, you can always retap the hole for another thread pitch.

you can always screw it in place long enough to have someone TIG weld it and then remove the screws altogether .....hell its probably all scratched to hell and back now with all your thread guessing [smilie=011.gif]
