براغي ماكينة 5/16-18 × 5 بوصة | رأس جمالون محرك مشترك | فولاذ مطلي بالزنك (100/عبوة)

The truss head sits flat and clean once torqued, which made a difference on my thin steel frame. The combination drive let me switch between a socket and a screwdriver without hunting for the right bit, and all 100 came out of the bag free of any coating defects.

Used these for attaching a metal bracket to a wooden frame, and the combination drive let me use either a Phillips or flathead without swapping bits halfway through. The zinc coating seems decently thick for the price, so I’m hoping they’ll hold up in the garage.

Got these for a small outdoor repair project and the zinc coating is holding up well after a couple of rain showers. The combination drive made it easy to use with either a Phillips or flathead bit.
