Product Description
The Simpson Titen HD 3/4 in. x 4 in. Heavy-Duty Screw Anchor (THD75400H) by Simpson is a high-strength screw anchor engineered for optimum performance in both cracked and uncracked concrete and masonry. Backed by testing under static and seismic loading conditions, this anchor's self-undercutting, non-expansion design makes it ideal for demanding structural applications, even at reduced edge distances and spacings.
Key Features
- Qualified for static and seismic loading conditions
- Thread design undercuts to efficiently transfer the load to the base material
- No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits
- Hex-washer head requires no separate washer and provides a clean installed appearance
- Carbon steel Titen HD utilizes a specialized heat-treating process that creates tip hardness for better cutting without compromising the ductility
- Zinc-plated carbon steel anchor can be used for temporary exterior applications
- Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications
- Caution: Use a Titen HD screw anchor one time only - installing the anchor multiple times may result in excessive thread wear and reduce load capacity
