Fractional Size A307 Grade A Carriage Bolt with Hot Dipped Galvanized Plating
Fractional Size A307 Grade A Carriage Bolt with Hot Dipped Galvanized Plating
Fractional Size A307 Grade A Carriage Bolts with Hot Dipped Galvanized (HDG) plating are designed for strong, corrosion-resistant fastening in outdoor and structural wood applications. Commonly used in deck construction, fencing, landscaping, pole barns, and general framing, these carriage bolts provide dependable clamping force with long-term durability. The combination of ASTM A307 Grade A strength and heavy-duty galvanizing makes them ideal for exterior environments and pressure-treated lumber.
A307 Grade A Steel for Reliable Structural Performance
Manufactured from low carbon steel and meeting ASTM A307 Grade A specifications, these carriage bolts are engineered for general structural and non-critical load applications. They offer solid tensile strength and ductility, making them suitable for wood-to-wood and wood-to-metal connections. A307 Grade A hardware is widely used in residential and light commercial construction where consistent performance and ease of installation are essential.
Domed Head and Square Neck Design
The round domed head delivers a smooth, finished appearance without exposed wrench flats, making it ideal for visible applications such as decking and fencing. Beneath the head, the square neck is designed to bite into wood during tightening, preventing rotation. This anti-spin feature allows for efficient installation by tightening the nut from one side with a wrench or socket, saving time on job sites.
Hot Dipped Galvanized Coating for Maximum Corrosion Resistance
The hot dipped galvanized finish provides a thick zinc coating that protects against rust, moisture, and harsh environmental conditions. HDG plating meets ASTM A153 standards and is highly compatible with treated lumber, making it the preferred choice for outdoor and structural wood projects exposed to rain, humidity, or coastal air.
