#14 × 2" براغي حفر ذاتي (TEK) | رأس مسطح فيليبس | فولاذ مطلي بالزنك (200/عبوة)

I mounted these on a metal shed frame and the self-drilling tip bit right through without any pilot hole needed. The Phillips drive seated firmly without stripping, and the zinc coating looks clean. Just what I needed for a solid steel-to-steel connection.

The flat head sits flush perfectly, and the self-drilling tip cut through 14-gauge steel like butter without any pre-drilling. I’ve already used about half the pack on a workshop frame, and not a single one stripped or snapped.

Finally found screws that actually bite into the metal without stripping the head—the self-drilling tip saves so much time. The zinc coating looks clean and seems solid against rust so far.
