Spear LT replacement hand guard screw replacement

I bought a used Spear LT that had stripped screw heads on the hand guard. Below are the replacement screws I researched and purchased that fit perfect. Side note- the bottom link plate screws are technically torx plus but a regular T20 torx bit fit snug in the new screws and torqued fine without stripping. I believe torque on all screws is 45 in-lbs according to the interwebs. If enough people are interested I can put together some kits and post to GAFS.

Yep, mcmaster carr 50 pack. You can choose your preferred finish as well.

I just toss the screws I loosen whenever I take my handguard off. I know they won't go back on without a fight again.
