3/8 In. X 7-1/4 In. RSS Star Drive Low Profile Washer Head Structural Screws (50-Pack)

GRK Fasteners structural screws are engineered for heavy-duty wood-to-wood fastening applications where strength and reliability are essential. These 3/8 inch by 7-1/4 inch screws provide an easy-to-install alternative to lag screws, eliminating the need for complex installation procedures while delivering superior holding power. Whether you're building decks, installing ledger boards, securing stair rails, mounting deck posts, or constructing playground equipment, these structural screws are code approved and perform reliably in both interior and exterior environments.

The integrated washer head design distributes load evenly across the joint surface, creating zero-gap connections and improving structural stability. With their self-drilling and self-tapping design, these screws penetrate wood efficiently without pre-drilling, saving time on the job site. The Climacoat corrosion-resistant finish (gold color) protects against rust and weather exposure, making them suitable for demanding outdoor applications like decks and playgrounds as well as interior structural work.

Features and Benefits
