Simpson Strong-Tie offers a wide variety of bolted holdowns offering lowdeflection performance for a range of load requirements. The HD9B holdown has been tested in accordance with ICC-ES's AC 155 acceptance criteria and are approved for use in vertical and horizontal applications. The HD9B bolted holdown incorporates the proven design of our HDQ8 SDS-style holdown and feature a unique seat design which greatly minimizes deflection under load. HDB holdowns are self jigging, ensuring that the code-required minimum of seven bolt diameters from the end of the post is met. They can be installed directly on the sill plate or raised above it and are suitable for back-to-back applications where eccentricity is a concern. HDBs are designed to provide loads for intermediate-load-range shearwalls, braced-wall panels and lateral applications.

California Proposition 65
⚠WARNING: – www.P65Warnings.ca.gov.
We are providing this warning pursuant to a law passed by California in 1986 called the “California Safe Drinking Water and Toxic Enforcement Act of 1986”, or “Proposition 65” for short.
A Proposition 65 warning does not mean a product is in violation of any product-safety standards or requirements. In fact, the California government has clarified that “[t]he fact that a product bears a Proposition 65 warning does not mean by itself that the product is unsafe.”
The California agency tasked with implementing Proposition 65 has also explained, “You could think of Proposition 65 more as a ‘right to know’ law than a pure product safety law.” See http://oehha.ca.gov/prop65/background/p65plain.html
