#6 x 3/8" A型鈑金螺絲 | 六角華司頭一字驅動 | 鋼 鍍鋅 (5000 顆/包)

Bought these for a small metal shelf build and the zinc coating seems solid, no rust so far after a few weeks in a damp garage. The #6 size was perfect for attaching thin brackets without splitting the material. Way better than using drywall screws for metal.

The hex head grabs a wrench nicely, and the zinc coating looks uniform across the batch. I’ve used maybe a hundred so far for fastening brackets to steel studs, and none have stripped or snapped. For the price per piece, this box is a solid deal for anyone doing serious metalwork.

Five thousand of these in one box—that’s a serious stash, and every single head has a clean slot that grabs the driver without slipping. The zinc coating feels smooth and even, so they’ll hold up fine in a dry garage.
