Customer Reviews (4.2 / 5 · 5 reviews)

Scarlett ★★★★★

Finally found small brass screws that actually seat flush in my antique clock case without stripping. The 800-count package is way more than I needed, but the price per screw is unbeatable.

Emma ★★★★★

The brass finish matches the vintage lamp parts I'm restoring perfectly. Each screw has a clean slot that takes a standard driver without slipping. Nice to have a bulk pack so I won't run short on my next project.

Evelyn ★★★★☆

I needed a small batch for a jewelry repair and these brass screws worked well—the slotted heads were easy to grip with tweezers. The quantity is generous for the price, though a few had slightly uneven threads.
