Picked up a pack for repairing a vise grip and was impressed by the zinc coating, it's holding up well without any rust spots. The hex socket drive makes tightening them down in tight spots a breeze.

The hex socket drive sits deep and true, so my Allen key grabs every time without stripping. Zinc plating looks uniform across the whole batch of 600, and they threaded into my precision assembly with zero resistance. Exactly what I needed for building out my tooling fixtures.

These M4 bolts are perfect for my jig and fixture builds; the hex socket drive makes them easy to tighten in tight spots. Class 12.9 alloy steel feels exceptionally strong for such a small screw, and the zinc plating looks clean and uniform across all 600 pieces.
