Part of the PrimeGuard Plus line, this screw features an integrated flat washer head profile that distributes clamping load across a broader bearing surface, reducing pull-through in structural lumber and engineered wood products. Sold by the box, this fastener is suited for contractors, framers, and structural tradespeople who require consistent, code-compliant fastening performance on the job site.\u003c\/p\u003e\n\u003cp\u003eThis structural screw is appropriate for residential and light commercial framing projects where Simpson-style connector plates, ledger boards, rim joists, or similar structural wood connections require rated fasteners. The flat washer head style is commonly specified where conventional hex or round head fasteners are not suitable for the connection detail. Installers working under IRC or IBC structural requirements will find this screw applicable to a range of wood-to-wood and metal-connector fastening tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat washer head design increases bearing surface and reduces pull-through in structural lumber\u003c\/li\u003e\n  \u003cli\u003ePrimeGuard Plus coating provides corrosion resistance for treated lumber and exterior applications\u003c\/li\u003e\n  \u003cli\u003eSold by the box for job-site quantity use\u003c\/li\u003e\n  \u003cli\u003eDesigned for structural connections in framing and connector fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a structural fastener for wood framing, engineered lumber, and metal connector applications typical of residential and light commercial construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified framer or carpenter following applicable IRC or IBC structural fastening requirements.
