Jacob ★★★★★

Finally got around to installing these on a metal shelf project and the 40mm length was perfect for the sandwich joints. The zinc coating has a consistent finish and none of the heads stripped when I torqued them down. Solid value for a bulk pack.

Sophia ★★★★★

The slotted heads grab a standard screwdriver perfectly, and the zinc coating gives me confidence they’ll hold up in my garage. A full 1,500 count means I’ll be set for years without needing a restock.

Owen ★★★★★

I needed a big batch of M3 screws for a project, and these 40mm ones with the slotted drive work perfectly for anchoring brackets. The zinc plating seems consistent and should hold up fine against occasional moisture.
