Alexander T. ★★★★★

I've been through several packs of M3 screws for RC car builds, and the hex socket drive on these is a nice upgrade from the Phillips heads I used before. The zinc plating seems to hold up well against my oily hands during assembly.

Penelope ★★★★★

Finally, a bulk pack of M3 screws where the threading is actually clean and consistent across all 900 pieces. I used a full bag for mounting jig components without a single stripped head or binding issue. The zinc plating looks uniform and should resist shop moisture well.

Hannah ★★★★★

Grabbed a pack for replacing worn screws on a few jigs. The hex socket drive fit perfectly with my allen key, and the zinc plating looks clean and consistent across all 900 pieces.
