5/16 In. In. X 6 In. L Star Hex Head W-cut Structural Screws

The GRK Fasteners RSS Structural Screw is a high-performance fastener engineered from specially hardened steel to deliver exceptional tensile, torque, and shear strength. Designed for both professional contractors and DIY builders, this screw excels in demanding construction and framing applications where reliability and durability are critical. Whether anchoring wood-to-wood connections, attaching hardware, or assembling structural components, these screws provide the holding power and corrosion resistance needed for projects that must last.

The sharp threads and self-starting fast-bite tip allow the screw to penetrate hardwood and other materials instantly, reducing splitting and the need for pre-drilling. The built-in washer head creates zero-gap joints for a clean, professional finish while centering the screw in pre-drilled hardware like hinges and connector plates. The round washer head has no sharp edges, unlike conventional lag screws, and the added shoulder underneath allows it to center in connector plates. For screws 3-1/8 inches and longer, the CEE thread design enlarges the screw hole for the non-threaded portion, allowing wood to settle easily and increasing drawing strength while reducing driving torque and splitting risk. These qualities make RSS screws an efficient alternative to traditional lag screws, particularly for applications exposed to moisture or weather.

Features and Benefits

• Hardened Steel Construction: Specially hardened steel provides high tensile, torque, and shear strength for heavy-duty structural applications.
• Self-Starting Fast-Bite Tip: Sharp threads and points penetrate instantly into hardwood and other materials, reducing setup time and the risk of splitting.
• Built-In Washer Head: Creates zero-gap joints for a clean finish and centers the screw in pre-drilled hardware without sharp edges.
• CEE Thread Design (3-1/8 In and Longer): Enlarges the screw hole for the non-threaded portion, allowing wood to settle and increasing drawing strength while reducing driving torque.
• Corrosion-Resistant Coating: Ideal for projects exposed to moisture, ensuring long-term durability in both indoor and outdoor environments.
