Review on 🔩 Powlankou 50pcs Stainless Steel Flat Head Rivet Nuts - 1/4"-20 Threaded Insert Nutserts by Brian Samaiyar

PRO. The material appears to be rust free. The surface of the head needs to be expanded so that it can better hold any material. The length of the shrinkage/flexion/compression area must also be increased to match the hold on the other side. Because it is so small, it often shrinks unevenly. (I used different tools, I made sure that the holes are the exact diameter there, the result is the same) CON is possible. If the compression area compresses too much it will push into the threaded area causing the bolts to break or stick and since there isn't enough surface area on the head to hold the material in place everything will decompress. I say it's possible because it could also be the screws used as well as the crimping/riveting tool. In general, of course, if they work perfectly, they're great. but be prepared to buy 50 to use 30. and also have tools for grinding, drilling, cutting those that don't crimp properly.
