Typical shim thickness between the Strong-Wall and top plates or header is 7/8" or less using Simpson Strong-Tie® Strong- Drive® 1/4"x6" screws (SDS). For additional shim thickness, see detail 7/SW1(PDF).
For holdowns, per ASTM standards, anchor bolt nuts should be finger-tight plus 1/3 to 1/2 turn with a hand wrench, with consideration given to possible future wood shrinkage. Care should be taken to avoid over-torquing the nut. An impact wrench should not be used.
Caution:
Drilling or cutting
