#8 × 1/2" براغي حفر ذاتي (TEK) | رأس ويفر فيليبس | فولاذ مطلي بالزنك (5000 / عبوة)

Used these on a metal garage shelving project and the self-drilling tip saved so much time. The wafer head sits flush, and the zinc coating has held up well in a slightly damp environment.

Installed a whole rack of shelving without any pilot holes and these zipped right through the steel studs like butter. The self-drilling tip saved me so much time over standard screws, and none of them snapped or stripped even with my impact driver on high.

The wafer head design sits flush on metal studs without snagging, and the self-drilling tip bites right in without needing a pilot hole. I just finished a big sheet metal project and went through over 4,000 of these without a single strip-out.
