Strong-Drive® SD Screw for Structural Connectors

Simpson Strong-Tie introduces the Strong-Drive® SD screw for use with our structural connectors. Designed to replace nails in certain products, the load-rated SD screw has been tested and approved for use in many popular Simpson Strong-Tie® products. In certain applications screws are easier and more convenient to install than nails, and the single-fastener load values achieved by the SD screws exceed those of typical 10d common or 16d common nails. In addition, the galvanized coating makes the SD screw ideal for interior and most exterior conditions.

The SD screw features an optimized shank which is specifically designed to match the fastener holes in Simpson Strong-Tie connectors. The hex head virtually eliminates cam-out and helps avoid stripping of the head. The sharp point of the screw enables fast starts, and the serrated threads reduce torque for improved drivability.

SD Screws for Use with Simpson Strong-Tie® Connectors

Tested and approved for use in many popular Simpson Strong-Tie® connectors for interior and most exterior applications.*

* See list of suitable connectors.
The single-fastener load capacity of the SD9 exceeds the capacity of a 10d common nail, while the single-fastener load capacity of the SD10 exceeds that of the 16d common nail
Ideal for use in tight spaces where using a hammer is inconvenient.
Optimized heat-treating for ductility and strength.
Mechanically-galvanized coating meets ASTM B695 Class 55, is recommended for use with certain preservative-treated woods and is compliant with the 2006 International Residential Code® (R319.3) and 2009 International Residential Code (R317.3.1).

For allowable loads of connectors using SD screws,
see Connectors Approved for Use with SD Screws below.

SD Screw Allowable Loads: Steel Side Plate

Lateral and withdrawal loads are based on testing per ICC-ES AC233.
Allowable loads are shown at the wood load duration factor of C_D = 1.00. Loads may be increased for load duration by the building code up to a C_D = 1.60.
Withdrawal loads are based on the entire threaded section installed into the main member.

SD Screw Allowable Loads: Wood Side Plate

Lateral and withdrawal loads are based on testing per ICC-ES AC233.
Allowable loads are shown at the wood load duration factor of C_D = 1.00. Loads may be increased for load duration by the building code up to a C_D = 1.60.
Withdrawal loads are based on the entire threaded section installed into the main member.
Withdrawal load for wood side member thickness of 15/32" is limited to the pull-through load of 130 lbs.
The 15/32" and 23/32" side members must be plywood or OSB with minimum equivalent specific gravities of 0.50 for DF and SP design values, and 0.42 for SPF and HF design values

Since testing of the SD screw is ongoing, Simpson Strong-Tie will continue to add newly approved connectors to this list.

Simpson Strong-Tie is in the process of seeking evaluation reports that include SD structural-connector screws. Check with your local building department to determine whether the correct size of SD structural-connector screws may be used as a suitable substitute for nails.
