Simpson Strong-Tie THDB25178H Titen HD® 1/4 in. x 1-7/8 in. Heavy-Duty Screw Anchor (100-Qty)
The Titen HD anchor is a high-strength screw anchor for concrete and masonry. It is designed for optimum performance in both cracked and uncracked concrete. The high-strength, easy-to-install Titen HD anchor has been tested and shown to provide outstanding performance in cracked and uncracked concrete under both static and seismic loading conditions. The self-undercutting, non-expansion characteristics of the Titen HD anchor make it ideal for structural applications, even at reduced edge distances and spacings. Recommended for permanent dry, interior non-corrosive environments or temporary outdoor applications.
Features

- 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
- Qualified for static and seismic loading conditions
- Carbon steel Titen HD utilizes a specialized heat-treating process that 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
