No. 10 X 3-1/8 In. L Star Round Head Yellow Zinc Steel Construction Screws 50 P

GRK Fasteners RSS structural screws are made of specially hardened steel engineered to deliver high tensile, torque, and shear strength for demanding construction and outdoor projects. These fasteners are designed as an efficient alternative to traditional lag screws, offering superior performance in carrying beams, ledger boards, stair rails, deck posts, and structural applications where strength and reliability are essential.

The sharp threads and points bite instantly into materials including hardwood, significantly reducing the splitting effect that occurs with conventional fasteners. The CEE thread design on screws 3-1/8 inches and longer enlarges the screw hole for the non-threaded portion, allowing wood to settle easily while increasing the screw's drawing strength. This thread design also reduces friction on the shank, lowering driving torque and further decreasing the likelihood of wood splitting.

Features and Benefits

• Star Drive Recess: Provides consistent torque without damaging the screw head.
• Yellow Climacoat Finish: Offers excellent corrosion resistance, making these screws suitable for both indoor and outdoor applications.
• Hardened Steel Construction: Ensures long-lasting durability and superior strength in heavy-duty structural connections.
• Washer Head Design: Built-in washer head with no sharp edges allows for zero-gap joints, provides a tight seal, and centers the screw in pre-drilled hardware like hinges and connector plates.
• CEE Thread Technology: Specially designed for screws 3-1/8 inches and longer to enhance wood settlement and increase overall connection strength.
• Instant Bite: Sharp thread and point design penetrates material quickly and efficiently.
