Review: They're screws.. - Arrived promptly, wrapped in cellophane. When you need screws, you need screws. I hate buying 400, because I really only needed one, but I'm not buying 20 or 50 for like 1 dollar less. Just get it. Great value. Screws appear to be formed decently well. First screw I grabbed threaded right into the tapped hole, so they appear to be good to go, at least from the one instance that I used one.
Review: Good - Good product

## Features

- Material: These flat head screws are made of durable grade 12.9 alloy steel and have black galvanized technology. Good corrosion resistance, high hardness and long service life.

The box is labeled with detailed stickers, and the corresponding product size and quantity are marked on the stickers for easy searching.
