What is the TPI of the scope base screws for a Remington 700 short action?  They must be metric.  I can not find a darn screw in MI for my picatinny base.

Rem. Scope base and sight screws are std. 6/48 gun screw threads, any shop should have them.

Ray, I'd be interested in why you were taken to task.  I have 3 Remington bolt rifles, each one is a different model number, and each one has the standard 6-48 threads for the base mounting holes. AFAIK, that is the standard on Remingtons, unless it is a special application or the gun has been altered by someone.

Sent you a PM.  No need to hash this out on the Forum.  More of a misunderstanding than anything.  I should have kept my mouth shut.

tres,

do you mean 4-40, not 8-40?   thought it went 8-56, 6-48, 4-40,
won't an 8-40 be a bit small for a scope mounting?

Well, here I go getting involved again.

The first number in a screw size is the diameter of the screw and the second number is the TPI,threads per inch).

The smaller the first number, the smaller the screw.  So, a 4-40 is a lot smaller than an 8-40 even though they both have 40 TPI.

AFAIK all Remington actions are factory drilled and tapped for 6x48 scope and sight mounting screws.,As are most other actions as well).  On heavy recoiling rifles, some shooters will have the screw holes enlarged to 8-40 figuring that the bigger screws will have greater holding power.

And that's all I know about that. :) :)

Do bigger screws really give more strength or is there no difference?

Many shooters believe so.  But I've always been a skeptic and I've never had a rifle with anything bigger than 6x48.

My thinking is that if 3 or 4 #6 screws shear off from recoil . . .:eek:

But, others will disagree and now we'll hear from them.

About the only time a 8-40 screw is needed is when the smith needs more money for doing a job that never needed done to begin with...........
6/48's are the standard gun mounting screws......
Age is a high price to pay for maturity.
