Steel Hex Head Tapping Screws for Concrete, Block, and Brick
Slotted/External Hex
External Hex
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 acrylic coated screws are also known as Tapcons.

Stainless Steel Hex Head Tapping Screws for Concrete, Block, and Brick
External Hex
These 410 stainless steel screws are more corrosion resistant than ultra-corrosion-resistant coated steel screws. They're also known as Tapcons. All 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.

Heavy Duty Hex Head Tapping Screws for Concrete, Block, and Brick
Zinc-Plated 410 Stainless Steel
Zinc-Plated Steel
Also known as Tapcons, use these screws in applications requiring high strength. All have a hex-washer head for a secure grip with a wrench. Drive into a hole with a hammer drill or socket wrench. Pull-out strength and shear strength values are 25% of the ultimate values.
410 stainless steel screws are strong, wear resistant, mildly chemical resistant, and magnetic. They have a zinc plating that adds extra corrosion resistance
Steel screws are strong and wear resistant. They have a zinc plating that adds some corrosion resistance, but they aren’t as corrosion resistant as stainless steel.

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 acrylic coated anchors are also known as Tapcons.

Stainless Steel Flat Head Tapping Screws for Concrete, Block, and Brick
These 410 stainless steel screws are more corrosion resistant than ultra-corrosion-resistant coated steel screws. They're also known as Tapcons. All 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.

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 corrosion-resistant-coated steel, they resist corrosion in wet environments. Length is measured from under the head.
