Review on 🔩 Pack of 20 M3 x 6mm Stainless Steel Thread Insert Nuts for Helical Repair - Threaded Repair Inserts by Marcus Munoz

They are of the highest quality on this planet and possibly some other planets. I've been using thread inserts for decades and this is the best I've used to date. I see no way they could be better than this. The smooth surface of the insert after installation is the biggest plus. SO many other brands put a drive cutout in there that turns out to be a weak point. It's bulletproof. I only have two complaints. Both are not related to the quality of the product, but rather the presence of an overall size and the lack of some specifications in other listings. At the moment I can only find two sizes (metric) at Revain and don't need to buy the whole range. I also bought a set but my M6-1.0 wore out very quickly and now I have no option to replace them unless I buy the whole set again. Which of course isn't an idea as I'll be left with hundreds of pieces that I'll never use. I'm glad I can easily get more M8-1.25 whenever I want. What metric size do I use most often. As for the lack of listing specifications. I don't often see the thread pitch listed for the outside of the insert. This seller/brand listing had this information so I rewarded them with my purchase. They are made to carve yourself, but often in situations where I use them. First, I partially screw in with a tap. Of course, everything runs much more smoothly. I love these things! Now let's ask some sellers to list some batches of M6-1.0 inserts :-)
