Scope base thread pitch

[mgardewine]

Hey guys, new to the site, will get to intro but have an urgent question. I ordered NOS scope base mounts for my mark II because I couldn't find new weavers in stock. The bases work great but the screws seem to be the wrong thread pitch. Can anyone tell me what the exact thread pitch is for the mount holes from savage?
Thanks,
Mat

6-48, which is an industry standard for base screws
