I am reasonably sure this topic has been addressed i dont seem to find it. I am looking to put a pic rail on my new to me 114 in .270, but when i start shopping i find that there are two different screw sizes. How do i know which one fits mine? According to the chart my 114 was manufactured sometime in 2004. Any advice would be helpful so thanks in advance.
This is what I was taught:
If you have a set of precision calipers, you can measure any screws that came with your firearm.
#6-48 screws outside diameter measures approximately .138"
#8-40 screws outside diameter measures approximately .164"
If you don't have a set of calipers or the screw to measure, you can use a 1/8" Allen key or hex wrench.
If the hex key fits snugly in the hole in your receiver, then it is drilled for #8 screws. Do not force the Allen key into to the receiver ---- the goal is not to damage the threads.
If the Allen key does not fit in the holes, your receiver is drilled for #6 screws.
If you are a visual learner, the link below is to a YouTube video from EGW that repeats this information.

also consider the profile of the head. Different rail manufactures have different angles etc...
The Dunning-Kruger effect is alive and well.
Good info gentlemen. It likely uses 6-48. But always, ALWAYS…. CHECK FIRST. Exactly as wildcat described. Or, if you follow the video link, you can’t mistake them.
the video was helpful as i had just ordered the egw rail thanks

Im not sure u believe the egw comes with th 6-48 so if they dont fit i will be heading to the local hardware store the rail should be here sometime today
It probably has the screws in the package. The shortest screw goes all the way to the front.
In some cases the screw is too long and runs into the barrel thread. This is something you do not want to happen.
Put the front screw in first. Tighten it down until snug, not tight. Try to move the rail. If the rail is seated on the action proceed until all are snug and then torque them.
Always remove the front rail or mount screw before you remove a Savage barrel. Trust me on this one. I don't want to have to send you the tap.
