#12 × 2" براغي صفائح معدنية من النوع A | رأس مسدس سداسي مع شق قيادة | فولاذ مطلي بالزنك (2000 / عبوة)

These were exactly what I needed for securing down some metal siding, the hex washer head really helps keep them from pulling through. Zinc coating seems solid enough for outdoor use so far, and having 2000 in a box means I won't run out midway through the job.

I needed a bulk pack for a large roofing project, and these hex washer heads made installing them a breeze with a socket driver. The slotted drive worked fine, but I mainly used the hex for better torque. Good value for the price.

Went through about 600 of these today fastening metal roofing panels, and the hex washer head really does keep the surface from denting like standard screws can. The zinc finish feels decently thick and they drove straight without snapping.
