Customer Reviews (4.4 / 5 · 5 reviews)

Ella ★★★★★

Used a full pack on a marine robotics frame, and the 316 stainless held up perfectly after a week in saltwater. The flat head sits flush without any wobble, exactly what I needed for tight clearance spots.

George K. ★★★★★

Got these for a jig I’m building, and the 316 stainless is exactly what I needed for outdoor exposure—no corrosion worries so far. The flat head sits flush nicely, and the partial threading made alignment a breeze. Pack of 200 feels like a solid value for the price.

Thomas Y. ★★★★★

I needed stronger fasteners for a machinery jig, and these 316 stainless screws handled the torque perfectly without stripping. The partially threaded design made alignment easier than I expected.
