1
Tabulated values must be multiplied by all adjustment factors included in the NDS for dowel-type fasteners to determine
allowable loads for use with ASD and/or design loads for use with LRFD.
2
Tabulated values are applicable to screws installed perpendicular to the faces of the wood members.
3
The tabulated reference withdrawal design value is in pounds-force per inch of thread embedment into the main member.
4
Embedded thread length is that portion of the screw held in the main member including the screw tip.
