Halloween Special Bulk 3/4"-10 Grade A Hex Bolts (a307, Coarse Thread, Hot-dipped Galvanized) Accessory [M4veoKsO]

Heavy-Duty Corrosion-Resistant Fasteners for Industrial & Structural Use

For high-strength, corrosion-resistant fastening, trust 3/4"-10 ASTM A307 Grade A Hex Bolts. Manufactured from low carbon steel with a Hot-Dipped Galvanized (HDG) finish, these bolts provide enhanced durability and protection against rust and corrosion. Ideal for outdoor, marine, infrastructure, and industrial applications, they ensure long-lasting performance in extreme environments.

Note – PT = Partial Thread

Key Specifications

  • Material: Low carbon steel (ASTM A307 Grade A compliant)
  • Tensile Strength: 60,000 psi minimum tensile strength
  • Thread Size: 3/4"-10 Coarse Thread (UNC)
  • Finish: Hot-Dipped Galvanized (HDG) for superior corrosion resistance
  • Head Style: Standard hex head for easy wrench tightening
  • Compliance: Fully meets ASTM A307 Grade A specifications

Why Choose Hot-Dipped Galvanized (HDG)?

The HDG process coats steel bolts in a thick, durable layer of zinc, offering enhanced protection against corrosion. This finish is particularly valuable in:

  • Outdoor and Marine Applications: Provides superior rust resistance, making it ideal for bridges, docks, and marine environments.
  • Infrastructure and Construction: Ensures long-lasting durability in structural projects exposed to moisture, weather, and chemicals.
  • Industrial and Utility Installations: Prevents premature wear in power plants, water treatment facilities, and telecommunications projects.

Differences Between ASTM A307 Grade A & B

Understanding the differences between A307 Grade A and Grade B is crucial for selecting the right bolt for your project:

  • Grade A: Designed for general-purpose applications, including construction, infrastructure, and industrial equipment fastening. These bolts have a minimum tensile strength of 60,000 psi and are widely used for everyday structural needs.
  • Grade B: Specifically made for flanged joints in piping systems with cast iron flanges. These bolts have a slightly higher tensile range (60,000 to 100,000 psi) and require heavy hex heads for added strength.
  • Why Choose Grade A for 3/4"-10 Hex Bolts? Grade A is ideal for securing structural elements, mounting heavy equipment, and general-purpose fastening. Its broad usability makes it the go-to choice for large-scale construction projects.

Benefits of ASTM A307 Grade A with HDG Finish

  • Superior Corrosion Resistance: The HDG coating extends bolt life in high-moisture and salt-exposed environments.
  • Reliable Performance: Manufactured with a minimum tensile strength of 60,000 psi, ensuring secure fastening in demanding applications.
  • Versatile Construction Fastener: Commonly used in commercial buildings, bridges, and heavy equipment manufacturing.
  • Standard Compatibility: Easily integrates with HDG nuts and washers, making replacement and installation simple.

Industries & Applications

  • Structural Steel & Construction: Ideal for bolted connections in commercial buildings, bridges, and heavy-duty frameworks.
  • Marine & Coastal Projects: Perfect for securing piers, docks, and waterfront structures.
  • Utility & Infrastructure: Essential for power plants, water treatment facilities, and outdoor installations.
  • Outdoor Industrial Equipment: Used in securing fencing, light poles, and communication towers.

Installation Tips

  • Use the Right Wrench: Standard hex head bolts require an appropriately sized wrench or impact socket for installation.
  • Torque Properly: Follow recommended torque guidelines to avoid over-tightening or under-tightening, ensuring optimal performance.
  • Use HDG-Compatible Hardware: Always pair HDG bolts with matching HDG nuts and washers to maintain corrosion resistance.
  • Store Properly: Keep bolts dry before installation to preserve the protective zinc layer.

Bulk Purchasing Advantages

  • Cost Savings: Buying in bulk lowers the per-unit cost, making large projects more affordable.
  • Consistent Quality: All bulk orders are sourced from the same production lot, ensuring uniform strength and reliability.
  • Fast Availability: Large stock ensures quick fulfillment, keeping your project on schedule.
  • Ideal for Contractors & Manufacturers: Whether you're assembling heavy machinery or working on a large-scale build, having a bulk supply reduces downtime.
