A307 Threaded Rod

A307 Threaded Rod for General Construction

A307 threaded rod is a standard choice for a wide range of general construction and structural applications. Manufactured from low carbon steel and designed to meet ASTM A307 Grade A specifications, these rods offer consistent tensile strength, reliable thread form, and cost-effective performance for anchoring, bracing, and fabrication needs.

Whether you're using it in wood-to-concrete connections, hangers, or pipe supports, A307 threaded rod is a trusted, jobsite-ready fastener for commercial, residential, and industrial projects.

What Is A307 Threaded Rod?

ASTM A307 specifies a grade of low carbon steel bolts and rods intended for general-purpose construction. A307 Grade A threaded rod is fully threaded end-to-end and commonly used in:

• Light to medium-duty structural anchoring
• Mounting plates or base connections
• Suspended supports for piping or ductwork
• Formwork or temporary bracing applications
• General fabrication or steel assembly

These rods are easily cut, welded (in untreated finishes), and paired with standard nuts and washers for custom assembly.

Available Finishes

• Plain Steel: Cost-effective option for interior or dry environments where corrosion is not a concern
• Zinc-Plated: Provides mild corrosion resistance for indoor or protected use
• Hot-Dip Galvanized: Heavy-duty corrosion protection for exterior or embedded concrete applications

Select the finish that best suits your environment, especially when planning for outdoor or long-term installations.

Why Choose A307 Threaded Rod?

• Meets ASTM Standards: Manufactured to A307 Grade A specifications for structural confidence
• Versatile & Easy to Work With: Cut-to-fit, weldable (plain), and compatible with standard nuts and couplers
• Available in Multiple Diameters & Lengths: Supports small assemblies to large anchor setups
• Trusted Across Trades: Used by contractors, steel fabricators, framers, electricians, and HVAC pros

Common Applications for A307 Rod

• Concrete anchoring (with epoxy or expansion anchors)
• Suspended ceiling grid systems or pipe hangers
• Mounting electrical or mechanical components
• Metal framing and fabrication
• Building restoration or seismic retrofit hardware

Installation Tips

Threaded rod can be cut on-site to custom lengths. Always pair A307 rod with compatible grade nuts and washers for reliable performance. If embedding into concrete, verify embed depth and adhesive or anchor type for structural compliance. For galvanized rod, avoid mixing with incompatible metals to prevent galvanic corrosion in moist environments.

Frequently Asked Questions

• What is the tensile strength of A307 threaded rod? A307 Grade A has a minimum tensile strength of 60 ksi (60,000 psi), suitable for general-purpose fastening, not high-strength tension applications.
• Is A307 rod weldable? Yes, plain finish A307 rod can be welded. Zinc- and galvanized-coated rods should not be welded without proper precautions.
• Can I use this for anchoring to concrete? Yes, A307 threaded rod is commonly used in anchor systems with mechanical anchors or epoxy adhesives.
• Is it fully threaded? Yes, all A307 rods sold through Fasteners Plus are fully threaded unless otherwise noted.

Whether you're reinforcing a base plate, fabricating custom hangers, or anchoring into concrete, A307 threaded rod provides dependable strength and flexibility for a wide range of jobsite needs.
