Review on 🔩 120pcs Mixed Zinc Plated Carbon Steel Rivet Nut Flat Head Insert Nutsert Assortment Kit #8-32UNC #10-24UNC 1/4"-20UNC 5/16"-18UNC 3/8"-16UNC by Jontrell Fernandes

I've used almost all the sizes that came with them and they all worked as intended. My only complaint is that there are no instructions on what size drill bit is needed for each insert size. Not all of them are made to the same specifications at all of the companies that make them. I have some of the earlier work that required a 19/64" hole to properly install a certain size insert. Where the same insert required a 17/64" bit in this set. Not a big deal as I just mic'ed each insert to figure out which bit I needed to set up and adjust properly. 10-24UNZ 1/ 4"-20OZ 5/16"-18OZ 3/8"-16OZ
