براغي ماكينة 5/16-18 × 5-1/2 بوصة | رأس مسطحة بشق | فولاذ مطلي بالزنك (100 / عبوة)

The slotted head was easy to drive with a standard flathead screwdriver, and the zinc coating looks like it’ll hold up fine in my garage workbench project. These 5-1/2" screws were just the right length for securing thick brackets without needing extra washers.

Installed these in a wooden gate hinge today—the 5-1/2" length grabbed deep into the frame and the zinc coating should keep them from rusting in the light rain.

The slotted head on these 5/16-18 screws made them a breeze to drive with a standard flathead bit. For this length, the zinc coating on the shaft seems solid enough to handle a few damp days in my shed project.
