Softwoods and Hardwoods
Details shown for hardwood and softwood (as defined by AITC) are based on recommended minimum embedment depths of 11 screw diameters for softwoods and 7 screw diameters for hardwoods. When these minimum recommended embedment depths can not be reached, the following tables may be used to determine the allowable total anchor loads for 2 fasteners in parallel and perpendicular shear. The allowable withdrawal load in tension may be calculated from the detail by multiplying the allowable tension value shown by the actual embedment depth of the typical screw.
Where the drawings refer to parallel and/or perpendicular shear, it refers to the direction of the forces with respect to the grain of the wood. All threaded fasteners are assumed to be commercial quality, Grade 2.
