براغي ذاتية الحفر (TEK) مقاس #10 × 1/2 بوصة | رأس بانها فيليبس | فولاذ مقاوم للصدأ 410 مطلي بالزنك والبرونز (1000/عبوة)

I was a bit skeptical about them being self-drilling, but these #10 screws cut through thin metal sheeting effortlessly with no pilot hole needed. The pan head sits flush and the bronze tint looks nice against the grey paneling.

Used these to attach a metal sign to a steel frame, and the self-drilling point went through without me having to pre-drill a single hole. The bronze-tinted zinc finish looks nicer than plain silver hardware, and the Phillips head seated cleanly in my driver. All 1000 arrived organized and rust-free

The pan head design on these #10 self-drilling screws sits flush and holds tight in light-gauge steel, and the zinc plating on the 410 stainless steel gives them a nice, even finish. I used about 300 of them on a ductwork project yesterday without a single strip or break.
