Review: Clamping in style - Quality stainless product no issues fit like a glove on the trailer see no signs of rust or deterioration
Review: Nylon nuts should only be used on 1” or less thread length - Used on square pole for solar panels. The nylon nuts wouldn’t screw all the way before locking onto the threads. Had to replace with regular nuts and lock washers. Should have gotten shorter bolts. I didn’t remove any stars as that’s on me. The nylon nuts would’ve been great if I only 1” or less of threading was used.
