For SI: 1 inch = 25.4 mm, 1 pound = 4.448 kPa.
1
Tabulated reference lateral design values, Z, apply to single shear (two-member) connections with wood main and side members having specific
gravity as shown, in which the screw is oriented perpendicular to the grain and loaded laterally either parallel or perpendicular to the grain. For
connections in which the main and side members have different specific gravities, use the lower of the two. Gaps are not permitted between the main
and side members.
2
Values must be multiplied by all applicable adjustment factors, in accordance with Section 4.1.
3
Unless otherwise noted, side members with thicknesses greater than the tabulated minimum side member thickness may be used, provided the
corresponding tabulated minimum main member penetration is still achieved for the given screw length.
4
Minimum main member penetration is the minimum length of the screw (including threaded, unthreaded and tip length) that must be embedded within
the main member. The entire threaded portion of the screw must be embedded in the main member, unless otherwise noted.
5
The ThruLOK must be installed with the washer and nut, and must penetrate through the opposite face of the main member a sufficient distance to
allow the nut to be tightened snugly against the main member, with at least
1
/
2
inch, and no more than 1
1
/
2
inches of the ThruLOK screw engaged within
the nut.
6
Full embedment of the threaded portion of the screw in the main member is not required.
7
Side member thickness must not be increased.
8
Thickness of main member. Fastener must penetrate through the main member.
9

inch wood side member with specific gravity of 0.50 to minimum 1 inch thick rimboard. Rimboard consists of laminated strand
lumber (LSL) with an equivalent specific gravity of 0.50. Fastener must penetrate through the rimboard.
