With nearly 60 years of field and R&D experience, Simpson Strong-Tie ® timber connectors are manufactured to the industry's highest standards. Unmatched Quality from the Truss to the Foundation Submit registration Structural Connections Perp: Perpendicular-to-grain loading in the side member and perpendicular-to-grain loading in the main member, except where the main member is loaded parallel-to-grain.Para: Parallel-to-grain loading in the side member and perpendicular-to-grain loading in the main member.

Screws shall be installed into the side grain of the wood side member with the screw axis at a 90-degree angle to the surface of the member.

The main and side members shall be sawn timber or structural composite timber with the design density or equivalent design density typical of JD4 and JD5 grades.Minimum penetration into the main member shall be 25mm.The Main Member is the part where the fastener tip is embedded the Side Member is part adjacent to the head.Lateral Characteristic Design Value, Q kL (N) Stud-to-Top and Bottom Plate connection.Installation guide included in pack to help ensure proper installation angle.Fastening can be performed before or after exterior sheathing is applied for added flexibility.Can be installed from inside the structure, eliminating exterior work on the upper stories and enhancing job safety.Wide tolerance on installation angle makes it easy to install the SDWC correctly - Installation guide included to help ensure proper installation angle.Type-17 Point for faster starts and easier driving.Fully-threaded shank engages the entire length of the fastener, providing a secure connection between the roof and wall framing members.Orange colour for easy inspection of 152 mm screws.Cap Head countersinks fully into the double top plate to avoid interference with plasterboard or finish trades.MaterialĮ‑Coat™ (SDWC15600 with Orange Topcoat) Features & Benefits The SDWC has also been tested in accordance with ICC-ES AC233 (screw) and AC13 (wall assembly and roof-to-wall assembly) for uplift and lateral loads between wall plates and vertical wall framing and between the top plate and the roof rafters or trusses. The SDWC uplift values listed were analysed and calculated based on the characteristic values determined following AS1649-2001 (Timber-Methods of Test for Mechanical Fasteners and Connectors-Basic Working Loads and Characteristic Strength). The fully-threaded shank engages the entire length of the fastener providing a secure connection. When cross-grain bending or cross-grain tension cannot be avoided, mechanical reinforcement to resist such force should be considered.The Strong‑Drive ® SDWC Truss Screw provides a truss and rafter-to-top plate connection as well as a method to fasten stud-to-top and bottom plate.For Continuous Load Path, connections must be on same side of wall. Installation inside of wall is acceptable.

Hurricane tie is shown installed on the outside of wall for clarity.Allowable loads on wood have been increased 60% for wind or earthquake loading with no further increase allowed reduce where other load duration factors govern.See Fastening Systems for more information on Simpson Strong-Tie fasteners.For Continuous Load Path, connections in the same area must be on same side of wall. Loads are based on attachment of cold-formed steel members having a minimum thickness of 33 mil (20 ga.).These products are available with additional corrosion protection.
