DSC Drag-Strut Connector
The DSC drag-strut connector transfers the diaphragm shear forces from the girder truss or beam to the shearwalls. The DSC5 has been designed to optimize fastener location, resulting in a connector that outperforms the DSC4 with fewer fasteners. The DSC2 is a smaller, lighter version that installs with fewer screws.
Key Features
- The DSC5 requires 40% fewer fasteners than our previous DSC4, and gets 12% higher loads
- Left-hand and right-hand versions available
- DSCs install with the 1/4" x 3" Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws provided
Material
- DSC2 — 7 gauge; DSC5 — 3 gauge
Finish
- DSC2 — galvanized; DSC5 — Simpson Strong-Tie® gray paint
Installation
- Use all specified fasteners; see General Notes
- Strong-Drive SDS Heavy-Duty Connector screws are provided

Load Tables
- Allowable loads have been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
- Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws minimum penetration is 2 3/4", minimum end distance is 2 1/2" for DSC2 and
3 3/4" for DSC5 and minimum edge distance is 5/8" for full load values. - Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2014 Section 7.5.3.4 are met (pre-drilling required through the plate using a maximum of 5/32" bit).
