براغي حفر ذاتي (TEK) #8 × 3/8" | رأس سداسي بدون محزز | فولاذ مطلي بالزنك (2000 / عبوة)

Bought these to attach some metal brackets to steel studs, and the self-drilling tip saved me from having to pre-drill every hole. The 3/8" length was perfect for my thin-gauge application, and the zinc plating looks clean and corrosion-resistant. Worked flawlessly with a hex bit driver.

The hex head on these screws made it easy to get a solid grip with my driver, and they bit right into the metal stud without any pre-drilling. They hold tight and finish clean, which is exactly what I needed for this project.

Punched through 20-gauge steel like butter without needing a pilot hole — the self-drilling tip is a real time-saver. Pack of 2000 should last me through several projects, and the zinc coating seems decent for preventing rust.
