براغي ذاتية الحفر (TEK) مقاس #10 × 3/4 بوصة | رأس بانيل فيليبس | فولاذ مطلي بأكسيد أسود (200 / عبوة)

The black oxide finish on these held up well while I was driving them into steel studs, no stripping or snapping even with a cheap bit. The self-drilling tip punched through cleanly without any pilot holes, which saved me a solid chunk of time on a metal shelving project.

Bought these to attach some thin metal brackets, and the self-drilling tip really does save a step—no pilot hole needed. The black oxide finish looks clean, and the Phillips head drives nicely without stripping. Only nitpick is the 200-count pack feels a bit light for the price.

I needed some screws that could bite into steel without pre-drilling, and these TEK screws saved me that extra step. The self-drilling tip worked smoothly even on thin gauge metal, and the whole pack of 200 should last me through several more projects.
