• Code listed under IBC/IRC in accordance with ICC-ES AC193 and ACI 355.2 for cracked and uncracked concrete per ICC-ES ESR-2713 
• Code listed under IBC/IRC in accordance with ICC-ES AC106 for masonry per ICC-ES ESR-1056 
• Qualified for static and seismic loading conditions 
• Thread design undercuts to efficiently transfer the load to the base material 
• Standard fractional sizes 
• Specialized heat-treating process creates tip hardness for better cutting without compromising the ductility 
• No special drill bit required — designed to install using standard-sized ANSI tolerance drill bits 
• Testing shows the Titen HD installs in concrete with 50% less torque than competitor anchors 
• Hex-washer head requires no separate washer, unless required by code, and provides a clean installed appearance 
• Removable — ideal for temporary anchoring (e.g., formwork, bracing) or applications where fixtures may need to be moved 
• Reuse of the anchor to achieve listed load values is not recommended 

Applications 
The anchor is made from Carbon Steel, and is zinc plate. This anchor is designed for use in

Environment 
The anchor is designed for use in a dry environment.

Head Style 
The anchor is a Hex Washer Serrated head and is designed to allow the head to sit on top of the surface of the item being attached.

Hole Diameter/Bit Diameter 
The anchor requires a 1/4" hole to be drilled in the base material (). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill.

Driver Required 
A 3/8" is required for driving the anchor into the base material.

Diameter of Anchor 
The diameter of the anchor is 1/4".

Length Anchor 
The length of the anchor is 3"

Packaging 
The anchor is packaged with 50 pieces per box .

Depth of Hole 
The depth of the hole that is required for the anchor should be a minimum of 1/2" deeper than the anchor will penetrate the concrete. This will allow space for dust created during the installation process to fall, which will prevent the anchor from bottoming out in the hole before full penetration into the concrete.

Fixture Hole Diameter 
The hole in the fixture or material being fastened must be larger than the designated diameter of the anchor. The 1/4" diameter anchor requires the hole in the fixture to be 3/8".

Wrench Size 
The size of the wrench required to turn the nut to set the anchor is 3/8".

Torque Value 
To be set properly in the concrete, the anchor must be torqued to between See PDF
