Customer Reviews (4.8 / 5 · 5 reviews)

Michael M. ★★★★★

The flat heads sit perfectly flush in my jig's counterbores, and the hex drive made installation quick without stripping. For the price per piece, these are far more consistent than the mixed bin of random screws I had been using.

Penelope ★★★★★

The hex socket drive seated perfectly on my driver with zero wobble, and the 12.9 alloy steel feels rock solid for the jig I'm building. Zinc plating looks clean and even across all 200 pieces, no stripped threads in the batch.

Claire ★★★★★

These are exactly what I needed for rebuilding a precision assembly fixture. The hex socket drive made installation much easier than using a standard hex head, and the Class 12.9 alloy steel feels solid.
