Samuel W. ★★★★★

Used a handful of these to fix a loose hinge on a wooden jewelry box, and they fit perfectly without any stripping. The brass finish has a nice warm tone that blends right in, and the slotted heads were easy to drive with a standard screwdriver. For the price, getting 200 of these feels like a steal

Benjamin L. ★★★★★

The brass finish matches the vintage hardware on my project perfectly, and the 5/16-18 threads bit cleanly into the pre-drilled holes. I’ve got plenty left over for future repairs, which is a nice bonus for the price.

Penelope ★★★★★

The slotted drive head accepted my standard screwdriver without cam-out, which was a relief for these small brass screws. The 5/16-18 threads started cleanly in pre-drilled holes for a decorative plate.
