#14 × 1-1/2" براغي ذاتية الحفر (TEK) | رأس سداسي مع غسالة | فولاذ مطلي بالزنك (200/عبوة)

I used these #14 TEK screws to fasten metal roofing panels, and the self-drilling tip made quick work of punching through 16-gauge steel without needing to pre-drill. The hex washer head sat flush and grabbed tight with just a light touch from my impact driver. The zinc plating looks clean and shoul

The hex washer head sits flat and spreads the load exactly like it should, and the zinc finish looks clean on the metal I’m fastening. Drove a bunch of these into steel studs without a single stripped head or broken bit. For 200 screws at this price, they’re a solid buy.

These hex heads sat perfectly flush on my steel framing, and the self-drilling tip cut through without needing a pilot hole. Zinc coating has held up fine in my damp garage so far.
