Jason ★★★★★

Got these for a jig I'm building and the 316 stainless is exactly what I needed for outdoor shop work. 1500 pieces in the bag means I won't run out for a long time, and the flat heads sit perfectly flush in my counterbores.

Madison ★★★★★

These 316 stainless screws are holding up perfectly in a saltwater environment jig I built, no rust at all after three weeks. The hex socket drive made installation tool-free and quick, even in tight spots.

Lily H. ★★★★★

Finally, a full package of 1,500 M3 screws in 316 stainless steel that actually arrives neatly packed and fully threaded. The hex socket drive is crisp and doesn’t strip, which is a huge relief for jig assembly work. These feel denser and more corrosion-resistant than the 304 ones I’ve used before.
