Customer Reviews (4.8 / 5 · 5 reviews)

Jason H. ★★★★★

I needed some corrosion-resistant fasteners for an outdoor jig, and these 18/8 stainless steel cap screws fit perfectly without any binding. The hex socket drive gripped tight with my Allen key, making installation quick and clean.

Amelia ★★★★★

The threads cut clean and the hex drive seated perfectly on my torque wrench, no stripping even on the third install. I've got a whole drawer of these for fixture work and they hold up way better than the zinc ones I used to buy.

Stella G. ★★★★★

Used a handful to rebuild a jig in my shop — the hex drive seated firmly without stripping, and the stainless finish is a nice bonus for outdoor use.
