Customer Reviews (4.8 / 5 · 5 reviews)

Chloe B. ★★★★★

The brass finish looks great on my small electronics project, and they’re easy to drive with a standard slotted screwdriver. For 800 pieces at this price, the corrosion resistance alone makes them a solid buy.

Joshua M. ★★★★★

Finally got around to using these for a small jewelry box hinge project. The #4-40 size is tiny but perfect for delicate work, and the slotted drive takes a standard screwdriver without stripping. They hold just fine for light-duty use, and the non-magnetic part is a nice bonus for electronics.

Emily C. ★★★★★

I bought these for a small electronics project, and the brass finish adds a nice look while the slotted drive makes them easy to tighten by hand. The 1/8-inch length is perfect for thin panels, and having 800 screws means I won’t run out anytime soon.
