Customer Reviews (4.6 / 5 · 5 reviews)

Grace ★★★★★

The external tooth lock washers are already attached, saving me a ton of assembly time. I used these for mounting a small circuit board and the Phillips drive seated nicely without stripping. The zinc coating looks clean and uniform across all 300 pieces.

Madison ★★★★★

These pan head screws fit perfectly into my small electronics project, and the Phillips drive made assembly quick without stripping. I also appreciated how the external teeth bit into the metal right away.

Eva I. ★★★★★

The zinc plating on these #4-40 screws gives them a clean, consistent look, and the pan head seated perfectly flush in my project. A full box of 300 means I won't run out mid-job. Just wish the package included a few extra for inevitable drops.
