Tapcon 410 Stainless Steel Phillips Flat Head Concrete Screws are designed for fastening into concrete, brick, or block, delivering lasting performance in tough jobsite conditions. Made from tough 410 stainless steel, these screws are strong enough to hold tight in concrete and resist rust.

The Phillips flat head offers a clean, finished appearance and is ideal for countersunk applications where flush seating is desired.. With aggressive Hi-Lo threads and a Nail-Type tip, Tapcon screws bite quickly into masonry, reducing installation time while maximizing holding power.

These screws are commonly used for securing electrical boxes, wood or steel furring strips, and fixtures directly to concrete or masonry substrates. No anchors required, just a properly sized pilot hole and you're ready to drive.
