براغي ماكينة 5/16-18 × 6 بوصة | رأس تراس مع محرك مزدوج | فولاذ مطلي بالزنك (100 / عبوة)

The combination drive made it easy to install these with either a Phillips bit or a wrench. Used them to secure a heavy shelf bracket, and they held up great without any rust so far. Nice, sturdy feel for the price.

Used them to bolt down a workbench leg that kept wobbling, and the 6-inch length gave plenty of bite into the wood frame. The zinc finish is holding up fine after a few humid weeks in the garage, no rust spots yet. Combination head means I grabbed whatever driver was closest and it just worked.

The combination drive is a lifesaver when you're swapping between a Phillips bit and a flathead without hunting for the right tool. These screws threaded cleanly into my steel brackets and the zinc coating looks like it'll hold up fine in the garage.
