Low Carbon Hex Head Lag Screw Hot Dipped Galvanized Plating

Low Carbon Hex Head Lag Screws – Hot Dipped Galvanized for Exterior Structural Strength

Low Carbon Hex Head Lag Screws with Hot Dipped Galvanized (HDG) coating are engineered for heavy-duty outdoor fastening where corrosion resistance and structural integrity are critical. Designed for wood-to-wood and wood-to-masonry connections, these lag screws are widely used in deck construction, fencing, pergolas, retaining walls, dock assemblies, and exterior framing. When projects demand long-term durability in harsh weather conditions, HDG lag screws provide the strength professionals trust.

Low Carbon Steel for Toughness and Workability

Manufactured from ductile low carbon steel, these hex head lag screws deliver an ideal balance of tensile strength and flexibility. The reduced carbon content minimizes brittleness, helping prevent cracking under heavy loads. This makes them well-suited for structural wood applications requiring dependable clamping force. Low carbon steel also ensures smoother installation and consistent thread performance.

Hex Head Design for High-Torque Installation

The hexagonal head allows for secure driving with a wrench or socket, enabling maximum torque application. This design ensures tight material draw-down and strong joint integrity in structural assemblies. Whether fastening beams, ledger boards, or treated lumber components, the hex head configuration supports precise and controlled installation.

Hot Dipped Galvanized Coating for Superior Corrosion Protection

The hot dipped galvanized finish provides a thick zinc coating that protects against rust, moisture, and environmental exposure. Unlike standard electroplating, HDG coating offers enhanced durability in wet, coastal, and chemically aggressive environments. This corrosion-resistant layer meets ASTM A153 standards and is compatible with pressure-treated lumber, making it ideal for exterior construction.

Coarse Threads for Strong Wood Engagement

Deep, aggressive threads and a sharp point allow these lag screws to penetrate wood fibers effectively, creating a secure mechanical bond. Pre-drilling pilot holes is recommended to prevent splitting and ensure optimal performance.
