Drilling into concrete or brick usually means hammer drills, plastic anchors, and frustration when the anchor spins or pulls out. These 1/4" x 3-1/4" concrete screws (also known as Tapcon-style masonry screws) cut those extra steps. You just drill a pilot hole with the included carbide bit, then drive the screw directly into the hole – no anchor needed. The hex washer head accepts a multi-drive tool (slotted, hex, or Phillips), and the deep cutting threads bite into block, brick, or stucco. This 220-piece kit comes with two drill bits and one driver bit, plus a sturdy plastic storage box. Whether you're attaching furring strips to a concrete wall, mounting shelves in a garage, or securing a patio railing, these blue rust-coated carbon steel screws are up to the task.

🔩 Why This Concrete Screw Kit Stands Out

Complete kit – 200 screws + bits – Includes 200 hex washer head concrete screws (1/4" x 3-1/4"), 2 masonry drill bits, and 1 driver bit. Everything you need to start fastening right out of the box.

No anchors required – The self-tapping design with deep high-low threads grips concrete, brick, and block directly. Just drill a pilot hole (using the included bit) and drive the screw. Faster than hammer drills and expansion anchors.

Hex multi-drive head – The slotted hex head works with a hex socket, flathead screwdriver, or Phillips bit. You're not stuck with one tool type – use whatever's in your pouch.

Blue rust finish for durability – Surface treatment provides extra wear resistance, corrosion resistance, and oxidation resistance compared to plain carbon steel screws. Ideal for both indoor and covered outdoor applications.

Sharp diamond tail for fast drilling speed – The pointed tip with aggressive cutting edges helps the screw self-start into the pilot hole, reducing installation time.

Wide application range – Works in concrete block, brick, stucco, mortar joints, and even some lightweight masonry. Perfect for attaching electrical boxes, conduit straps, wood furring strips, metal brackets, and fence posts to masonry surfaces.

📐 Technical Specifications – Concrete Masonry Screw Kit

*Note: Always use the included carbide drill bit sized according to manufacturer recommendation (typically 3/16" or 5/32" for 1/4" screws). Drill hole 1/4" deeper than screw length to allow for dust.
