Customer Reviews (4.6 / 5 · 5 reviews)

Elizabeth ★★★★★

I used these for a jig fixture at work, and the hex socket drive made installation straightforward even in tight spots. The partially threaded design gave just the right grip for clamping a steel plate without bottoming out.

Lily C. ★★★★★

The zinc plating looks clean and even across all 25 bolts, and the hex socket drive seated my allen key without any wobble. Class 12.9 hardness gives me confidence these will hold up in my jig setup without stripping.

Lily ★★★★★

The partially threaded design made alignment a breeze when securing a fixture plate, and every single screw seated cleanly without any galling. The zinc coating looks uniform across all 25 pieces, and the hex socket drive held up fine under a breaker bar at full torque.
