Steel Hex Head Tapping Screws for Concrete, Block, and Brick

Slotted/External Hex

External Hex

These blue and silver 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 corrosion-resistant-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 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 corrosion-resistant-coated screws 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.
