For SI: 1 inch=25.4 mm, 1 lbf=4.45 N,1 ksi=6.89 MPa.
'The side member must be steel having a minimum tensile strength (F.) equal to 45 ksi when the steel member design thickness is from
0.0584 inch to 0.1795 inch,and a minimum F.equal to 52 ksi when the steel member design thickness is 0.2405 inch.
2The main member must be wood having a minimum assigned specific gravity of 0.50, such as Douglas fir-larch, and must be sufficiently
sized to accommodate the screw length less the thickness of the side member.
'The uncoated minimum steel thickness of the cold-formed product delivered to the jobsite must not be less than 95 percent of the tabulated
design thickness,t,
4 Holes in the steel side member must be predrilled or prepunched.Hole diameter must comply with Section 3.2.3 of this report.
5Tabulated lateral design values (Z)must be multiplied by all applicable adjustment factors, including the load duration factor, GD, from the
NDS as referenced in the IBC or IRC.
6S crews must be installed into the side grain of the wood main member with the screw axis perpendicular to wood fibers.
'Minimum fastener penetration must be equal to the screw length less the thickness of the metal side plate.

For SI: 1 inch=25.4 mm,I lbf=4.45 N.
'The actual thickness of the wood side member, t., must be either 11/2 or 13/4 inches, as specified in the table. The wood side member
thickness is an absolute value,and is not a minimum or maximum value.
2 The tabulated lateral design values(Z)are based on wood members having the same assigned specific gravity of 0.50,such as Douglas fir-
larch,
'The wood main member must be equal to or greater than the screw length less the thickness of the wood side member.
4 Tabulated lateral design values (Z)must be multiplied by all applicable adjustment factors, including the load duration factor, Co, from the
NDS as referenced in the IBC or IRC.
5Screws must be installed into the side grain of the wood members with the screw axis perpendicular to wood fibers.

whichever is the more restrictive.
2 Values for spacing between staggered rows apply where screws in adjacent rows are offset by half of the spacing between screws in a row.

'The tabulated reference withdrawal design value(W= 172 lbs/inch)is in pounds per inch of the thread penetration into the side grain of the
main member.
2 Tabulated reference withdrawal design values(W= 172 lbs/inch)must be multiplied by all applicable adjustment factors from the NDS as
