Hannah ★★★★★

These screws threaded smoothly into my jig without any binding, and the hex socket held the Allen key perfectly even at higher torque. The 12.9 alloy steel feels incredibly sturdy for the price.

Isabella N. ★★★★★

The black oxide finish on these screws looks great and seems like it'll hold up well against rust in my shop. They fit perfectly into my jig fixtures without any binding, and the hex drive made installation quick.

Abigail N. ★★★★★

I needed some tough fasteners for a heavy-duty tooling fixture, and these 12.9 alloy steel screws threaded in smoothly without any binding. The black oxide finish looks great and seems like it'll resist rust well in my shop.
