Review on Pieces Stainless Bolt Dropper Insert by Damon Atonyo

I ripped off two bolts trying to fully install these nuts on the bolt and then unscrewed them as they wouldn't let solve. I used ¾" and ⅜" bolts with washers to bolt on the tool box in my truck. On each bolt the nut was unscrewed about 1/4 inch when they stopped turning. After a 15 minute nut fight with everyone trying to unscrew the nut, the bolts broke. The locking material must not be the same material that I assigned to the bolt. Drop it and they were great to deal with!
