Customer Reviews (4.8 / 5 · 5 reviews)

Edward ★★★★★

I was relieved these little screws fit perfectly into a tight jig I’m building for a small press project. The 18/8 stainless steel feels solid and won’t rust, which is crucial for my workshop environment.

James P. ★★★★★

The hex socket drive grips the allen key perfectly, no wobble or stripping even when I torqued them down in a tight spot. The 18/8 stainless finish looks clean and hasn't shown a speck of rust after a week in a damp shop. Exactly the precision I was after for my tooling setup.

William ★★★★★

I needed a few for a small jig I was building, and the 18/8 stainless steel feels much sturdier than the zinc-plated ones I've used before. The hex socket drive made it easy to tighten them down without stripping.
