Low Carbon Hex Head Lag Screw Hot Dipped Galvanized Plating

Low Carbon Hex Head Lag Screws – Hot Dipped Galvanized: Heavy-Duty Fastening Built for the Outdoors

When your project demands rugged strength and long-term corrosion resistance, low carbon hex head lag screws with hot-dipped galvanized (HDG) plating are the go-to choice. These screws are designed for heavy-duty wood-to-wood and wood-to-masonry connections, making them ideal for deck construction, fencing, outdoor framing, marine applications, retaining walls, and more.

Manufactured from low carbon steel, these lag screws offer the ideal combination of toughness and ductility—easy to install and resistant to brittle fracture. The hex head design allows for maximum torque application using a wrench or socket, making installation straight forward and secure.

The real strength lies in the hot-dipped galvanized coating, which adds a thick, corrosion-resistant zinc layer. Unlike electroplated finishes, hot-dipped galvanizing provides long-lasting protection in wet, salty, or chemically aggressive environments, making these fasteners perfectly suited for outdoor and coastal use. This finish also meets or exceeds ASTM A153 standards for corrosion resistance.
