ASTM A307 Grade A All Thread Rods with Hot Dipped Galvanized Plating
Freight Policy for Items 3 Feet in Length and Longer
Oversized Item Shipping Guidelines
Items 3 feet in length and longer do not qualify for free freight, even if the order meets the standard free freight threshold. These oversized products are excluded from free freight calculations and will be shipped at current UPS published rates.
Items Over 6 Feet
Products longer than 6 feet require truck freight shipment. Freight charges will be calculated after the order is received and submitted for customer approval prior to shipment. These items are also excluded from free freight qualification and free shipping promotions.
ASTM A307 Grade A All Thread Rods – Hot-Dip Galvanized (HDG)
Rugged Corrosion Protection for Outdoor and Structural Applications
ASTM A307 Grade A all thread rods with hot-dip galvanized (HDG) plating are the go-to fastening solution for general-purpose structural and construction projects where enhanced corrosion resistance is required. Manufactured from low carbon steel, these rods are designed for light to medium-duty applications and provide long-lasting durability in outdoor or exposed environments.
What Is ASTM A307 Grade A?
ASTM A307 Grade A defines the standards for low carbon steel fasteners used in non-critical structural connections. These fully threaded rods are ideal for use in suspension, bracing, anchoring, and light framing systems.
With UNC (Unified National Coarse) threading, these rods are compatible with standard nuts and washers, allowing for quick and easy assembly in the field.
Benefits of Hot-Dip Galvanized Finish
Hot-dip galvanizing adds a thick, bonded layer of zinc that protects the steel from rust and corrosion. Key advantages include:
-
✅ Superior corrosion resistance for outdoor or high-moisture environments
-
✅ Ideal for treated lumber, decks, and structural steel installations
-
✅ Longer lifespan compared to electroplated zinc finishes
-
✅ Excellent performance in infrastructure and utility construction
Sizes and Common Uses
These rods are available in diameters from 1/4" to 1-1/2" and in lengths such as 6', 10', and 12', with custom sizes available. Common applications include:
-
Outdoor framing and anchoring
-
Utility pole hardware and fencing
-
HVAC and plumbing support in damp environments
Dependable Strength Meets Outdoor Durability
When your project requires cost-effective fastening with maximum weather resistance, ASTM A307 Grade A all thread rods with hot-dip galvanized plating are built to last.
