Customer Reviews (4.8 / 5 · 5 reviews)

Owen W. ★★★★★

I needed these for a jig I was building, and the hex socket drive made installation a breeze even in tight spaces. The 18/8 stainless steel feels solid and corrosion-resistant, exactly what you want for precision work.

Brian Y. ★★★★★

Finally found the right length for a fixture I’m building, and these 3-1/4" screws fit perfectly with no wobble in the hex socket. The stainless steel feels solid, and the threads cut clean into my tapped holes.

Andrew G. ★★★★★

The hex drive on these screws grabs perfectly without stripping, which was my main worry buying online. They fit tight in my jig frame and the stainless finish looks clean.
