1 Based upon ASD design loads. Values shall be multiplied by the applicable adjustment values provided in the 2024 National Design Specification (NDS) for Wood Construction.
2 Withdrawal values are pounds per inch of thread including the tip but excluding the length of the upper 4CUT™. Minimum penetration into the main member is 1-1/2" for the 1/4" and 5/16" diameters, 2" for the 3/8" diameter, and 3" for the 1/2" diameter.
3 Head pull-through values are based upon a 1-1/2" side member.
4 Lateral shear capacity is based upon a 1-1/2" side member and at least 1-1/2" penetration into the main member for the 1/4" and 5/16" diameters or 3-1/2" for the 3/8" or 1/2" diameters.
5 Tabulated values are based upon the specific gravities in the NDS. For specific gravities not listed, use the next lower value. When the connection has two different species, use the lower specific gravity.
