Help with correct size Torx screws for scope base....

[muggs13]

I am getting ready to mount an older Leupold 20 MOA MK 4 scope base to my Remington 700P SA and don't have the Torx screws. I know they are 6-48, however what length do I need?

Thanks in advance !

Buy a torx screw kit. It will come in handy in the future. You can always use a longer screw and cut to length. I generally do this to get the best thread engagement possible

Any hints on how to cut such a small screw without destroying the threads?

I hold the screw in a small bench vise and cut with dremel with cut off wheel. Then a small file to clean up the cut

Usually I’m able to find a screw from the kits I have to work. But in the past I have cut the front screws on bases where the screw would engage the barrel threads before tightening down

Every guy should have at least a couple sets of these laying around. You can also use to hold screw while cutting/grinding and helps straighten threads when you back out - https://www.brownells.com/gunsmith-...s/u-s-screw-chek-r-sku080670001-775-2976.aspx

easiest way on small smaller screws is to buy and nut as well.
put the nut on first
chop off
unscrew/take off nut
it cleans the threads up on the way off
30 seconds and your done

or take a few minutes with a small file and follow the threads

Depending on the screw head, chuck the screw head in a cordless drill and using a bench grinder grind the end while spinning the screw.

Also when you clamp the screw down, you clamp onto the nut, don't ruin the threads higher up with your vise/wrench.

Need more clamping area? Stack up 2-3 nuts!
