Grip-rite GRSSHW51631820 Structural Screws

Product Description

The GRIP-RITE GRSSHW51631820 is a hex washer head structural screw from the PrimeGuard Plus line, engineered for structural fastening applications in wood-frame construction and related trade work. The hex washer head design provides a broad bearing surface and high drive torque, making these screws well suited for connecting structural members where code-compliant fastening is required. Licensed contractors and experienced builders use these fasteners where reliable clamping force and shear resistance matter. Sold by the box, they are a practical choice for jobs requiring consistent, production-rate installation.

These structural screws are used in wood-to-wood and wood-to-engineered-lumber connections in residential and light commercial framing. Typical applications include ledger attachment, rim board fastening, and general structural panel or framing connections where a high-strength screw fastener is specified in lieu of or alongside traditional nails or bolts. The hex washer head allows installation with a standard hex driver bit or socket, reducing cam-out during high-torque driving.

Compatibility

Designed as a structural replacement or specified fastener for wood-frame construction assemblies requiring hex washer head screw fasteners. Verify local building code and fastener schedule requirements before installation.

Installation Notes

Installation is typically performed by licensed contractors or qualified carpenters following applicable building codes, including IRC and IBC fastener schedule requirements. Use a calibrated hex driver or impact driver set to the appropriate clutch setting to avoid overdriving. Inspect the fastener schedule in the project drawings before installation to confirm screw size, spacing, and pattern. Do not substitute structural screws for engineered connector hardware without engineering approval.
