Grip-rite GRSSHW921250 Structural Screws

Product Description

The GRIP-RITE GRSSHW921250 is a hex washer head structural screw from the PrimeGuard Plus line, engineered for structural fastening applications in wood framing and construction assemblies. The hex washer head design provides a large bearing surface and allows installation with a standard hex driver or impact tool, reducing cam-out and improving torque transfer. These screws are sold by the box and are suited for professional framers, structural carpenters, and contractors working on load-bearing connections where code-compliant fasteners are required.

Structural screws in this category are commonly used in residential and light commercial framing, ledger board attachments, post-to-beam connections, and general wood-to-wood structural assemblies. The PrimeGuard Plus coating provides corrosion resistance, making these fasteners appropriate for treated lumber applications and exterior or exposed framing conditions where standard zinc fasteners may not meet code.

Key Features

• Hex washer head design for high torque transfer and reduced cam-out during installation
• PrimeGuard Plus coating for corrosion resistance, including compatibility with treated lumber
• Designed for structural wood-to-wood fastening applications
• Compatible with standard hex drivers and impact drivers
• Sold by the box for jobsite quantity use

Compatibility

Designed as an OEM-style structural fastener for use in wood framing and structural lumber assemblies where hex washer head screws are specified.

Installation Notes

Installation is typically performed by licensed carpenters or structural contractors. Drive with a calibrated impact driver or hex bit driver to avoid over-driving, which can compromise structural integrity. Always verify that the fastener meets local building code requirements, including IRC or IBC prescriptive fastening schedules, before use in load-bearing connections. When fastening into pressure-treated lumber, confirm that the coating rating meets ACQ or CA treatment compatibility requirements per the fastener manufacturer.
