Can I substitute products like Simpsons SSTB anchors for anchor rods at tie-downs?
These anchors typically perform just as well as standard anchor rods. Simpson manufactures the threads on their anchors by roll-forming them, not by cutting them. The threads do not always come out perfectly round in this process. You should check to make sure that a nut will thread onto the anchor BEFORE you cast it into your footing. Otherwise you will need to dress the threads on the anchor with a threading die before you can attach a tie-down to it. You will need to check with the design professional if your plans show something besides this sort of anchor.
