براغي ذاتية الحفر (TEK) #8 × 3/8 بوصة | رأس بان مع محرك فيليبس | فولاذ مطلي بالزنك (2000/عبوة)

I needed a bulk pack for a roofing project, and these self-drilling TEK screws saved me from pre-drilling every single hole. The zinc-plated finish seems good so far, and the pan head sits flush against the metal.

Bought these for a quick metal-to-metal job and the self-drilling tip went through 20-gauge steel without me having to pre-drill a single hole. The zinc coating looks consistent across all 2000 pieces, and the Phillips drive didn't cam out once with my impact driver. Box arrived sealed and organized

The pan head seats flush without stripping, which is exactly what I need for thin metal framing. Drilled through both layers cleanly without a pilot hole, and the 2,000 count means I won't be reordering for a while.
