Customer Reviews (4.8 / 5 · 5 reviews)

Sebastian V. ★★★★★

Grabbed a box for some furniture assembly, and the combination drive means I can use a Phillips or square bit without swapping tools. The plating is smooth and even, giving them a clean finish that looks good on exposed brackets.

Aurora R. ★★★★★

The truss head on these screws sits nice and flush on thin metal brackets, which saved me from having to countersink anything. The zinc coating looks uniform, and the combo drive let me use either a Phillips or flat bit without stripping.

Violet O. ★★★★★

The combo drive worked perfectly with both my drill and a hand ratchet, saving me from swapping bits on a long framing job. These 6-inch screws bit into the studs cleanly without pre-drilling, and the zinc coating feels solid enough for the shed shelf I just hung.
