Jacob ★★★★★

Finally found brass screws that match the old hardware on my restoration project. The slotted drive works perfectly with a standard screwdriver and the 200-pack means I won't run out halfway through.

Eli Z. ★★★★★

The round head sits flush enough for my antique mirror frame, and the brass matched perfectly. I'm glad I got the 200-pack for just this one small project—plenty left for future repairs.

Richard K. ★★★★★

Used a handful of these to secure a small sign, and the slotted brass heads look a lot classier than plain steel. The corrosion resistance is a nice bonus for anything that might get damp.
