Grip-rite GRSSFW38420 Structural Screws Box

Product Description

The GRIP-RITE GRSSFW38420 is a flat washer head structural screw from the PrimeGuard Plus line, designed for structural fastening applications in wood-frame construction. These screws feature an integrated flat washer head profile that distributes load across a wider surface area, reducing pull-through in structural panels, ledgers, and framing members. The washer head design provides a secure, flush-bearing seat that standard hex or bugle-head screws do not offer. Licensed trades and experienced framers rely on this type of fastener where code-compliant structural connections are required.

This screw is suited for residential and light commercial wood-frame structural assemblies, including ledger boards, rim joists, shear wall panels, and similar load-bearing connections. The flat washer head is particularly effective in applications where bearing surface matters, such as through-fastening engineered lumber, OSB sheathing, or multi-ply framing. This product is sold by the box with a minimum order quantity of one box.

Key Features

• Flat washer head design provides increased bearing surface to reduce pull-through
• PrimeGuard Plus coating for corrosion resistance in treated lumber and outdoor exposure environments
• Structural-grade fastener suitable for load-bearing wood-frame connections
• Sold by the box for jobsite quantity use

Compatibility

Designed as an OEM-style structural screw replacement for flat washer head fastener applications in wood-frame construction projects.

Installation Notes

Installation should be performed by qualified carpenters, framers, or contractors familiar with structural fastening requirements under applicable building codes. Always verify that the fastener size and spacing meet local structural or shear wall nailing schedules before installation. Use an appropriate driver bit to avoid cam-out and maintain proper screw head seating. Do not overdrive screws, as this can compromise the bearing surface and reduce the load capacity of the connection.
