Kits like this are great to have around, you never know exactly what fasteners you will need to make an optic and plate fit your weapon correctly.

This screw kit is the perfect variety pack for any pistol optic owner. I bought a used optic with no screws, and other ones I tried were too long and made my slide inoperable—these fit perfectly and came pre-applied with Loctite. It worked great, and now I’ve got extra screws on hand for future setups.

Monstrum RMSc screw packetGave it four stars as I haven’t needed to use them yet. They look like good quality and have blue thread locker on the ends of the screws.Not much to say about these. They are tiny little screws for optics being mounted to particular items. Spares are nice to have, sometime you drop one, lose it, etc. Good to have around.Packet contents: all use the T10 wrench and have flat heads, 24 screws in total in the packMetric screws are all 5.0 mm in diameter3 – M3x0.5 – 11 mm length3 – M3x0.5 – 12 mm length3 – M4x0.7 – 10 mm length3 – M4x0.7 – 11 mm length3 – M4x0.7 – 12 mm length3 – M4x0.7 – 13 mm lengthStandard screws are all 5.5 mm in diameter3 - #6 32x0.433” – 11 mm length3 - #6 32x0.472” – 12 mm length

These are perfect if you have the 43X or 48 with the RMSc mount. Good quality screws with thread locker already applied.

**The Following Positive 5 Star Review of this Product Complies With All Amazon Vine Community Guidelines and Standards!**As a Professional Marksman and Competition Firearms Team Member as well as an Avid Hunter I work with a ton of Tactical Gear including RMRc Red Dots for my handguns! Over time the Screws that are holding the Red Dot to your Firearm will come loose and in extreme cases they'll fall out completely and you'll lose them!This RMRc Screw Set is the perfect solution for all of your Missing RMSc Mounting Screw Needs! This bag contains several size screws that will help you get back up and running again with your Red Dot! This is definitely the simple & easy solution for any Screws that are missing! The great thing about these Screws is that they are strong and look exactly like the originals that came with the Red Dot kit! They also have Blue Loc-Tite/Threadlocker already on them so it'll prevent these Screws from coming loose and falling out again! This feature makes it super easy to install on your Firearm! It works better than the actual screws that came with my Red Dot! Also I noticed that these Screws cost less than what they were charging at the gun store so you'll save some money here too!!I absolutely love this product and it's definitely important to have this packed along with your other Tactical gear!! Five Stars All the way for this product!! ⭐⭐⭐⭐⭐

Got these screws for my Shield Plus Carry Comp. Threads are perfect without any play. The screws do come with a dab of blue threadlock on them. I can't speak for screws other than the ones I used for my S&W. They take a T10 torx head.

It's so nice to have a backup set! these come in small individual bags labels perfectly! I try and change out the screws on my red dots every 2k rounds so that I don't have an issue at a competition. These make it so easy!! and they have both sizes i needed for two different setups!
