This set of screws was perfect for my needs. I was not sure exactly what length I needed so the variety was perfect. The screws were functional and the fit and finish were great. The hardened stainless steel is just what I was looking for to keep my optic intact during a long range visit. They also added blue Loctite to keep them in place.

Screw broke at 15 inch pounds of torque. Literally the trijicon rmr spec, torqued with an inch pound wrench. Now I have to get something to get the broken screw out that has loctite on it.

Unless you happen to be an expert on exactly what length and type of screw fits your particular combination of red dot and weapon, it’s pretty handy to buy a set like this so that you have everything you need. I like that they are in individually bagged and marked sets. The quality looks good, and this goes in my spare parts kit so that when I inevitably lose one, I’ve got them on hand. Obviously you could buy these separately and in larger quantities and get a better per piece price, but convenience has a value too.

**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 Red Dots, Lasers and Scopes!! Over time the Screws that attach these units to your Firearms come loose and at times they'll completely fall out and worst case you'll lose them!This Universal Screw Set is the perfect thing to have in your range bag as you can quickly replace any Screws that are missing or have corroded over time! The great thing is these Screws are strong and look exactly like the originals that came with my Red Dots, Lasers & Scopes! In addition, they have Blue Loc-Tite/Threadlocker already on them so it'll prevent these Screws from coming loose and eventually falling out again!I absolutely love this product and it's definitely important to have this in your range bag!! I'm rating this product Five Stars because it works!! ⭐⭐⭐⭐⭐

I recently stripped the screws in one of my optics and needed to replace them. Unfortunately I wasn't sure of the exact size I needed. However, this kit had multiple sizes in the correct thread pitch. And unlike mine sent that stripped these used a standard t10.

The 6-32s thread into my RMR slot no problem. A really nice fit for my T10 bit. The finish on them seems great so far too. Definitely appreciate the individual bagging and clear labeling.

I got these to see if they were the right size for a knife clip but they were not, not the fault of the screws, which are well made and I liked having the options of trying a few sizes, even if none worked for me.
