Simpson Strong Tie SDWS22400DB-R12 Timber Screw 12 Pack

Product Description

The SIMPSON STRONG TIE SDWS22400DB-R12 is a 0.220-inch diameter by 4-inch structural timber screw sold in a 12-pack. It features a double barrier coating engineered for corrosion resistance in exposed and treated-lumber applications. This screw is designed for heavy-load connections in wood framing, timber construction, and outdoor structural assemblies. Licensed contractors, framers, and deck builders install these fasteners where code-compliant, high-strength wood-to-wood connections are required. The double barrier coating provides protection against rust and weathering, extending service life in exterior and high-moisture environments.

This screw is suited for residential and light commercial structural applications including deck framing, heavy timber connections, ledger attachments, and post-to-beam assemblies. The 4-inch length and 0.220-inch shank diameter make it appropriate for connecting dimensional lumber and engineered wood products where withdrawal and shear strength are critical. Framers and structural carpenters reach for this fastener when a reliable, weather-resistant screw is needed for exposed or semi-exposed structural joints.

Key Features

• 0.220-inch diameter shank for high withdrawal and shear load capacity
• 4-inch length suitable for heavy timber and multi-ply lumber connections
• Double barrier coating provides corrosion resistance in exterior and treated-lumber environments
• 12-pack quantity supports typical structural connection work without frequent restocking
• Designed for consistent installation performance in production framing and deck-building workflows

Compatibility

Designed as an OEM-style structural fastener for use in heavy timber framing, deck construction, and similar wood-to-wood structural connections where a 0.220-inch by 4-inch screw profile is specified.

Installation Notes

Installation is performed by licensed framers, structural carpenters, or qualified contractors. Confirm that fastener selection meets applicable building code requirements, including IBC or IRC provisions for structural connections, before installation. Use an impact driver or heavy-duty drill with the appropriate drive bit to avoid stripping the head.
