Review on 🔩 10 Pack T-Track / T-Slot Through-Hole Knobs Bolts and Washers for Mini T-Tracks: Must-Have Jigs & Fixtures Accessories (1/4 inch x 20 tpi) by Jesus Carlson

The plastic looks good but is very soft. Cage nuts run out with minimal torque. Luckily this won't destroy the item as the nut can be put back on and reused until it breaks through the plastic again. I just buy wings when they inevitably fail. Also, the bolt doesn't slide smoothly in my T-track. Stamped lettering adheres to any imperfection or protruding setscrew. The head diameter is barely large enough to grip both sides of the rail and prevent the bolt from rotating.
