Product Description

Powers Fasteners Tapper® / concrete screw — 0.25" (1/4") diameter x 2.75" overall length, Phillips flat (countersunk) head masonry/tapper screw for fastening wood, metal or fixtures to concrete, brick and concrete block. Designed as a thread-forming concrete anchor (Tapper family) with matched carbide drill-bit and driver sizes (3/16" carbide pilot bit; #3 Phillips drive for 1/4" diameter), available in Perma‑Seal coated carbon steel and stainless variants for extended corrosion protection. Sold/installed as a single fastener (length measured from underside of head); typical installs require drilling the specified diameter pilot hole at least 1/4" deeper than screw embedment, cleaning the hole, then driving the screw until the head is tight against the fixture.
