Choosing the right structural connector

Reading the plan callout and matching Simpson Strong-Tie hardware.

December 10, 20255 min readDeWitt Lumber

Connectors are engineered products. The model number on the plan is not a suggestion, and the fastener schedule that comes with it is part of the rating.

Start with the callout

The plan or truss drawing names the connector. Substituting a similar-looking hanger with a different load rating voids the engineering, and it is the first thing an inspector checks on a framing inspection.

Fill every hole the schedule requires

A hanger rated for a given load assumes a specific nail or screw in a specific set of holes. Short-nailing a hanger is the most common field error we see, and it is invisible once the drywall is up.

Match the coating to the environment

Interior dry framing takes standard galvanized. Exterior, treated lumber, and anything near the coast or a pool needs the heavier ZMAX or stainless equivalents. We stock both — ask at the counter which the plan requires.
