Half Thread Hex Wood Screw – 5/16″ x 4-3/4″

Description

This Half Thread Hex Head Wood Screw (5/16″ x 4-3/4″) is a long structural fastener engineered for heavy-duty timber joinery applications including ledger board attachment, beam connections, and structural wood clamping. The half-thread design leaves a smooth unthreaded shank section below the head, which allows the screw to draw two members tightly together for a strong, gap-free joint — ideal where clamping force is required. The hex head allows easy installation with a socket wrench, nut driver, or impact driver. Zinc plating provides corrosion resistance for both interior and treated timber exterior use.
