Grip-rite GRSSFW51631820 Structural Screw

Product Description

The GRIP-RITE GRSSFW51631820 is a flat washer head structural screw from the PrimeGuard Plus line, designed for structural fastening applications in wood framing and construction assemblies. The integrated flat washer head distributes load across the fastening surface, reducing the risk of pull-through in structural connections. This screw is suited for professional contractors, framers, and trade workers who require a reliable, code-compliant fastener for structural work. Sold by the box, it is intended for job-site use where consistent performance across multiple fastening points is required.

This structural screw is typically used in residential and light commercial wood-frame construction. Common applications include connecting dimensional lumber, engineered wood products, ledger boards, and structural panels where a strong, secure mechanical connection is needed. The flat washer head profile makes it well-suited for applications where the fastener head must seat flush or near-flush against the work surface without countersinking.

Compatibility

Designed as an OEM-style structural fastener for use in wood-frame construction assemblies where flat washer head structural screws are specified.

Installation Notes

Installation should be performed by a qualified framing contractor or carpenter using an appropriate power driver set to the correct clutch setting to avoid overdriving. Always follow local building codes and engineer specifications when using structural fasteners in load-bearing connections. Verify that the fastener length and coating are appropriate for the lumber type, including ACQ or CA treated lumber where corrosion-resistant fasteners are required.
