- Allowable load adjustment factors shown in the table are applicable to all face-mount hangers, post bases and caps, and straight straps, except as noted in the footnotes below.
- Some products have been tested specifically with alternative fasteners and have allowable load adjustment factors or reduced capacities published on the specific product page. Values published on the product page may be used in lieu of using this table.
- This table does not apply to SUR/SUL/HSUR/HSUL hangers or to hangers modified per allowed options, or to connectors made from steel thicker than 10 ga.
- Strong-Drive® SD Connector and SD Connector SS screw substitutions in this table do not apply to sloped, skewed, or double-shear hangers. Strong-Drive® SD Connector screws and SD Connector SS screws may be used in these connectors. For additional information and specific allowable loads, refer to strongtie.com/sd. Where published allowable loads are for installation with #10 SD screws, multiply by 0.83 to obtain allowable loads for #9 SD screws.
- Where noted, 1 1/2" long fasteners may be substituted for the specified fastener into the header only; double-shear fasteners shall be minimum 2 1/2" long.
- Nails and Strong-Drive® SD Connector screws may not be combined in a connection.
- For straps installed over wood structural panel sheathing, use a 2 1/2"-long fastener minimum.
