Steel Hex Head Tapping Screws
for Concrete, Block, and Brick
These blue and silver ultra-corrosion-resistant coated steel screws stand up to wet environments. They have a hex head for a secure grip with a wrench. Drive into a hole with a hammer drill or socket wrench, or use a specialized tool set (sold separately). Pull-out strength and shear strength values are 25% of the ultimate values.
Blue ultra-corrosion-resistant coated screws are also known as Tapcons.

Steel Flat Head Tapping Screws
for Concrete, Block, and Brick
These blue and silver ultra-corrosion-resistant coated steel screws stand up to wet environments. These screws are beveled under the head for a flush finish in countersunk holes. Drive into a hole with a hammer drill or socket wrench, or use a specialized tool set (sold separately). Pull-out strength and shear strength values are 25% of the ultimate values.
Blue ultra-corrosion-resistant coated anchors are also known as Tapcons.

Tapping Screw Assortments for Concrete, Block, and Brick
Also known as Tapcons, these screws are often used to anchor parts to concrete, block, and brick. Screws have a hex head that allows for a secure grip with a wrench. Drive them into a hole with a hammer drill or socket wrench, or use a specialized installation tool (sold separately). Made from ultra-corrosion-resistant coated steel, they resist corrosion in wet environments. Length is measured from under the head.

Hex-Shank Masonry Drill Bits for Tapping Screw Installation
Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. Each is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. They have a built-in hex collar that acts as a stop for repeatable drilling depths. The split point keeps the bit centered without a pilot hole.
A drive sleeve (sold separately) slides over the drill bit to drive fasteners without removing the drill bit from the tool. One end engages with the hex-collar on the drill bit, while the other end holds a screwdriver bit.
