#12 × 3" براغي صفائح معدنية من النوع A | رأس غسالة سداسي مع محرك شق | فولاذ مطلي بالزنك (200 / عبوة)

I needed screws that wouldn't strip out in thin metal, and the sharp threading on these bites right in without needing a pilot hole. The flat hex washer head sits flush and distributes pressure evenly, so the panel I attached doesn't show any distortion.

The hex head made it easy to grip with a socket wrench, and the zinc coating looks clean on exposed metalwork. I’ve used about half the box on a shed frame and haven’t stripped a single slot yet, which says a lot for a slotted drive.

I needed some heavy-duty screws for attaching metal brackets to a steel frame, and these #12 hex washer heads really distribute the load perfectly. The zinc plating looks clean and seems tough enough to resist rust on the job.
