Review on Pieces Stainless Bolt Dropper Insert by Brandon Wynen

To be honest these are the worst locknuts ever. and 70 percent of them jam before they get that far, and then you have to physically break the machine screw to get them loose. over a dozen nuts and bolts. The threading on them is just wrong and they grip very easily, the good reviews are obviously from a previous batch. And it happens the same way with Chinese and American made stainless steel screws. Lock Nuts I used to work well from Bolt Depot. It's just that this is a totally unacceptable product that doesn't live up to specifications.
