براغي صفائح معدنية من النوع A #12 × 1 بوصة | رأس مسطح فيليبس | فولاذ مطلي بالزنك (200 / عبوة)

Used a few of these to fasten some heavy-duty shelving brackets to steel studs, and the undercut head really helps them sit flush without stripping. The zinc plating seems decent so far, no rust after a week in a slightly damp garage.

Picked up a pack of these for a quick HVAC duct repair and was surprised how cleanly the flat head sat flush with the metal surface. The zinc coating looks evenly applied, so I'm hoping they'll resist rust in the attic. Definitely saved me a trip to the hardware store.

These #12 screws bite into the metal studs perfectly without stripping, and the flat head sits flush every time. The zinc coating seems robust enough to hold up in my garage project.
