براغي ذاتية الحفر (TEK) مقاس #6 × 2 بوصة | رأس مسطحة مع محرك فيليبس | فولاذ مطلي بالزنك (100 / عبوة)

I was a little nervous about how well these would hold in thin sheet metal, but the self-drilling tip cut right through without any pilot hole. The 2-inch length was perfect for joining two layers of 20-gauge steel. They're a solid buy for the price.

Just finished a small metal framing job and these TEK screws punched through without any pre-drilling, which saved me a ton of time. The zinc coating seems sturdy so far, and the flat heads sit flush like they should.

The phillips drive on these grabbed my driver bit cleanly and the self-drilling tip went through thin steel without any pre-drilling. All 100 came out of the box straight and the zinc finish looks even across the batch, so I'm set for this whole project.
