براغي خرسانية تابكون 3/16" × 1-3/4" | رأس مسدس مع شق | فولاذ مطلي بالزنك (1000 / عبوة)

I drilled pilot holes into the garage floor slab and these zinc-plated screws seated flush with the hex washer head, holding the pressure-treated sill plate tight with zero wobble. Worked perfectly for the whole hundred-count box I used, and the slotted drive made driving them into the concrete feel

Needed to anchor a heavy shelf into an old garage wall, and these Tapcons held up perfectly. The slotted drive worked fine with a standard bit, and the whole box of 1000 is a great value for bigger jobs.

The hex washer heads on these screws really help distribute the load evenly when mounting brackets. Counted exactly 1000 in the box, and the zinc coating looks like it’ll hold up well in the garage. Finished my concrete fastening job in half the time I expected.
