The GRIP-RITE GRSSFW516625 is a flat washer head structural screw from the PrimeGuard Plus line, designed for heavy-duty fastening applications in structural assemblies. This screw features an integrated flat washer head that distributes load across a wider bearing surface, reducing the risk of pull-through in structural connections. Sold by the box, it is a standard fastener used by framers, structural carpenters, and general contractors working on residential and light commercial construction projects where code-compliant structural fastening is required.
This structural screw is suited for wood-to-wood and engineered lumber connections in framing, decking, and other load-bearing assemblies. The washer head design makes it a practical choice when fastening into materials where a larger bearing surface is needed to meet structural performance requirements. It is appropriate for both new construction and structural repair work.
Designed as an OEM-style replacement and standard structural fastener for use in residential and light commercial framing and structural assembly applications.
Installation should be performed by qualified carpenters or structural tradespeople in accordance with applicable building codes and project structural drawings. Always use the correct drive bit to avoid cam-out and fastener damage. Consult local building codes and engineered lumber manufacturer guidelines for fastener spacing, edge distance, and structural connection requirements before installation.
