براغي ذاتية الحفر (TEK) #12-24 × 1-1/2 بوصة | رأس مسدس سداسي | فولاذ مطلي بالزنك (200 / عبوة)

The hex washer head really spreads the load nicely when fastening into thin metal, and the self-drilling tip chews through without a pilot hole. Pack of 200 is plenty for a weekend project, and the zinc coating held up fine so far.

The hex washer head on these screws sits perfectly flush against the metal, no wobble or stripping. Used them to attach some steel brackets and they bit right in without any pilot hole. Solid pack for the price.

Bought these for a metal framing job and the #12-24 thread grabbed cleanly without any stripped holes. The hex washer head sits flush and spreads the load just like it should, and a full 200-count box means I didn't have to run back to the store mid-project.
