ASTM A307 Grade A All Thread Rods with Clear Cr3 Zinc Plating

ASTM A307 Grade A All Thread Rods – Clear Cr3 Zinc Plated

General-Purpose Threaded Rods with Enhanced Corrosion Resistance

ASTM A307 Grade A all thread rods with Clear Cr3 zinc plating offer a reliable, affordable fastening solution with added protection against corrosion. Designed for light to medium-duty structural and industrial use, these rods are widely used in construction, HVAC, electrical supports, and fabrication.

What Is ASTM A307 Grade A?

ASTM A307 Grade A covers low carbon steel fasteners commonly used in non-critical applications where moderate strength is sufficient. These fully threaded rods are ideal for bracing, hanging, anchoring, and assembly tasks that don’t require high tensile performance.

Featuring Unified National Coarse (UNC) threads, these rods are compatible with standard nuts and washers, making them easy to install and adjust on the job site.

Why Choose Clear Cr3 Zinc Plating?

The Clear Cr3 zinc plating provides a thin, bright silver-colored protective layer that offers improved resistance to rust and oxidation in indoor and mildly corrosive environments. Key benefits include:

• ✅ Corrosion protection in dry or slightly humid conditions

• ✅ RoHS-compliant, trivalent chromium for safer environmental impact

• ✅ Smoother finish than hot-dip galvanized alternatives

• ✅ Suitable for architectural or visible installations due to its clean look

Sizes and Applications

Available in standard diameters from 1/4" to 1-1/2" and lengths up to 12 feet, these rods are commonly used in:

• Electrical and mechanical supports

• Light structural connections

• Indoor framing and bracing

• General-purpose fabrication

A Cost-Effective Fastener with Extra Protection

For projects requiring reliable fastening and moderate corrosion resistance, ASTM A307 Grade A all thread rods with Clear Cr3 zinc plating are a smart, versatile choice.
