Hazel W. ★★★★★

The slotted drive bites nicely with a standard flathead, so no stripped heads on these 3/8-16s. The plain steel finish is exactly what I needed for indoor shelf brackets, and the 200 count means I’ve got plenty left over for future projects.

Edward ★★★★★

These little screws were perfect for a small jig I was building. The slotted round head makes them easy to drive flush on soft wood. Good value for a big pack when you just need some plain steel fasteners for indoor shop use.

Victoria ★★★★★

Used a handful to mount some hinges and the slotted drive bit into them cleanly without camming out. The plain steel finish is perfect for interior work where you don't need to worry about rust.
