I know this is 2+ year old post but someone else might benefit and prevent the same mistake I did.
I stripped a head of the screw off an EGW rail but it was my fault (over-torqued it). It was previously torque correctly but was working on other projects with higher torque setting and accidentally re-torque them :(.
Anyways, this tool worked like a champ and is worth the $20 (got mine at Home Depot) to keep in your DIY gunsmithing tool chest.
I voted for my "FREEDOM", "GUNS", and "MONEY" - keep the change - UNK.
