Edward V. ★★★★★

The slotted drive on these #4-40 screws made for a precise fit in my metal panel, and the zinc coating feels sturdy. A full 2000-count box means I won’t run out mid-project.

Eva ★★★★★

I needed small screws for mounting a circuit board in an aluminum enclosure, and these #4-40 x 3/4" round head slotted ones fit perfectly. The trivalent zinc coating gives them a clean, even finish that resists rust nicely.

Andrew ★★★★★

The trivalent zinc finish on these looks a lot more uniform than the cheap zinc-plated ones I’ve gotten before, so they’ll hold up better in a damp garage. Slotted round heads seated nicely into my steel brackets with a standard screwdriver, and the 3/4" length was perfect for stacking two panels. 2
