Simpson Strong-tie SDWS22600DB-RP1 Timber Structural Screw

Product Description

The SIMPSON STRONG-TIE SDWS22600DB-RP1 is an exterior-grade structural screw from the Strong-Drive SDWS Timber series, engineered for high-load wood-to-wood and timber connections. Designed to replace traditional lag screws and through-bolts in many structural applications, this fastener delivers reliable clamping force without pre-drilling in most installations. At 0.08 pounds per unit, it is a single-piece fastener sold individually. It is a go-to choice for contractors, framers, and structural carpenters working on load-bearing timber assemblies that require code-recognized performance.

This screw is suited for exterior structural applications including timber framing, ridge beam connections, ledger attachments, post-and-beam assemblies, and heavy wood connector installations. The exterior-grade coating makes it appropriate for outdoor, exposed, and treated-lumber environments where corrosion resistance is required. Licensed contractors and professional framers are the primary installers for this type of structural fastener in both residential and light commercial construction.

Installation Notes

Installation should be performed by a qualified framing contractor or licensed general contractor familiar with structural fastener requirements. Consult applicable building codes and the manufacturer load tables before use in engineered or permitted assemblies. Always verify that the substrate species, thickness, and connection geometry meet the published installation criteria for this fastener series. Do not substitute this fastener in connections that specify a different diameter or length without confirming equivalency with a structural engineer.
