Strong-Drive® SDW TRUSS-PLY Screw
Newly redesigned for faster starts and less torque while driving.
The Strong-Drive SDW Truss-Ply screw is a high-strength structural wood screw specifically designed for fastening multi-ply members, such as joining plated trusses and solid sawn lumber. The SDW installs easily with no predrilling and is available in optimized lengths for fastening 2-, 3- and 4-ply trusses. With the SDW Truss-Ply screw, multi-ply trusses and beams can be fastened from one side without requiring the lifting and flipping of heavy assemblies. It is code listed under IAPMO-UES ER-192 and meets 2012 and 2015 IRC® and IBC® code requirements for several common framing applications.
Key Features
- New — Patented SawTooth™ point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
- Large washer head provides maximum bearing area; stamped with the Simpson Strong-Tie “≠” sign and fastener length for easy identification after installation (0.75" head dia.)
- Deep 6-lobe T-40 recess reduces cam-out, making driving easier
- Low-profile head results in less interference after installation; makes stacking and sliding members easier and allows installation of hardware and finishes to be virtually flush
- Higher shear values than competitive products enable wider spacing, saving time and money
- Bold thread design provides superior holding power and cinches fastened members together for consistent installation
- Retail and mini-bulk packs include one 6-lobe, T-40 driver bit; bulk packs include two driver bits
Applications
- Truss-ply fastening

Load Tables
SDW TRUSS-PLY — Allowable Shear Loads — DF, SP, SPF, HF Lumber and 2x Truss Loaded on Head Side
- For minimum penetration into main member of 1 1/8", use 235 lb. for DF/SP and 210 lb. for SPF/HF.
Loaded on Head Side (3-ply assembly shown – other configurations similar)
SDW TRUSS-PLY — Allowable Shear Loads — DF, SP, SPF, HF Lumber and 2x Truss Loaded on Point Side
- For minimum penetration into main member of 1 1/8", use 235 lb. for DF/SP and 210 lb. for SPF/HF.
Loaded on Point Side (3-ply assembly shown – other configurations similar)
SDW TRUSS-PLY — Allowable Uniform Load (plf) Applied to Either Outside Member — Side-loaded Multi-Ply Assemblies
- Each ply is assumed to carry same proportion of load.
- Loads may be applied to the head side and tip side concurrently provided neither published allowable load is exceeded. (Example: a 3-ply DF assembly with a head side load of 1,300 plf and tip side load of 900 plf may be fastened together with 3 rows of SDW @ 16" o.c. between fasteners in a row.)
- When hangers are installed on point side, hanger face fasteners shall be a minimum of 3" long.
- Tables are based on Main Member Penetration as noted above.
- Hanger load spacing on the multi-ply assembly should not exceed 24" o.c. Exception: On a skewed girder, hanger loads up to 34" o.c. (resulting from joists uniformly spaced up to 24" o.c.) may be converted to a uniform load.
