ASTM A307 Grade A All Thread Rods with Plain Finish

ASTM A307 Grade A All Thread Rods – Plain Finish

Cost-Effective Threaded Fasteners for General-Purpose Applications

ASTM A307 Grade A all thread rods with a plain finish are a versatile, affordable solution for light to medium-duty construction and industrial applications. Manufactured from low carbon steel, these fully threaded rods are ideal for anchoring, bracing, and support systems in environments where corrosion resistance is not a primary concern.

What Is ASTM A307 Grade A?

ASTM A307 Grade A is a specification for low carbon steel fasteners used in non-critical structural connections. These threaded rods are commonly used with standard nuts and washers for tensioning, assembly, and alignment in projects that don’t require high tensile or yield strength.

With UNC (Unified National Coarse) threads, these rods are compatible with a wide range of standard hardware, offering easy installation and dependable performance for general-purpose use.

Plain Finish for Indoor or Coated Applications

The plain finish provides a clean, untreated surface suitable for:

• Indoor or dry environments

• Fabrication shops and temporary bracing

• Post-finish customization, such as galvanizing, painting, or plating

While not corrosion-resistant on its own, the plain finish allows for flexibility depending on your project requirements.

Common Sizes and Use Cases

ASTM A307 Grade A all thread rods are available in diameters ranging from 1/4" to 1-1/2" and lengths up to 12 feet, with custom cuts also offered. Common applications include:

• HVAC and plumbing supports

• Light structural framing

• Suspension of electrical systems or equipment

Dependable Strength for Everyday Fastening Needs

When your project calls for reliable, general-purpose fastening, ASTM A307 Grade A all thread rods with plain finish provide the perfect balance of strength, simplicity, and affordability.
