Simpson Strong-Tie BA412 4x12 Top Flange Joist Hanger - G90 Galvanized
Simpson Strong-Tie BA hangers are 14 gauge top mount hangers that are cost effective hangers featuring a min/max joist nailing option. Min Nailing featuring Positive Angle Nailing targets moderate load conditions whereas the Max Nailing generates capacities for higher loads. The unique two level embossment provides added stiffness to the top flange. The Strong-Tie BA412 top flange hanger features a G90 galvanized finish for added corrosion resistance and requires the use of hot-dip galvanized fasteners which meet the specifications of ASTM A153.

- Use all specified fasteners.
- LBAZ, BA, B and HHB may also be welded to steel headers with weld size to match material thickness (approximate thickness shown). The minimum required weld to the top flanges is 1/8" x 2" (1/8" x 1 7/16" for LBAZ) fillet weld to each side of each top flange tab for 14 and 12 gauge and 3/16" x 2" fillet weld to each side of each top flange tab for 7 gauge. Distribute the weld equally on both top flanges. Welding cancels the top and face nailing requirements. Consult the code for special considerations when welding galvanized steel. The area should be well-ventilated. Weld on applications produce the maximum allowable down load listed.
- Ledgers must be evaluated for each application separately. Check TF dimension, nail length and nail location on ledger.

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
