Strong-Drive® SDW TRUSS-PLY Screw 

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

  1. 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

  1. 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

  1. Each ply is assumed to carry same proportion of load.
  2. 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.)
  3. When hangers are installed on point side, hanger face fasteners shall be a minimum of 3" long.
  4. Tables are based on Main Member Penetration as noted above.
  5. 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.
