Review on 🔧 Set of 10 POWERTEC 71068 T-Track Knobs with 1/4-20 by 1-1/2" Hex Bolts, Washers - Enhanced SEO by Lamont Wilson

Bolts turn in the caterpillar. This is not the main question. On 8 out of 10 grips, my grips would not tighten more than a few turns. Plastic is pressed into the thread. I broke a toothpick trying to remove it. I have to find another way. I can't use a wrench, I'm sure the nuts will come out. Skip these guys. Edit: I spent 2 hours using another pick and Xacto knife to remove all the excess plastic. Fingernail-sized pieces of plastic protruded from them. Although now they work very smoothly.
