5/16"-9x1" Hex Head Lag Screw Clear Zinc Plating

Low Carbon Steel Hex Head Lag Screw with Clear Zinc Cr3 Plating – Rugged Fastening for Wood and Masonry Projects

The Low Carbon Steel Hex Head Lag Screw with Clear Zinc Cr3 Plating is a dependable, heavy-duty fastener ideal for wood-to-wood and wood-to-masonry applications. Manufactured from low carbon steel, this lag screw provides a strong yet cost-effective solution for structural and construction fastening where shear strength and long-term durability are key.

Featuring a hexagonal head, the lag screw allows for high torque applications using a standard wrench or socket, ensuring tight installation without the risk of stripping. The deep coarse threads cut into wood or pre-drilled masonry with superior holding power, minimizing slippage and loosening over time.

The Clear Zinc Cr3 Plating adds a clean, bright finish and offers enhanced corrosion resistance, making it suitable for indoor and light outdoor use. Trivalent chromium plating (Cr3) is a more environmentally friendly alternative to older hexavalent chrome coatings, aligning with modern RoHS compliance standards.
