ASTM A307 Grade A Hex Bolts Manufacturers

-- Steady & Reliable Manufacturer --

Introduction

ASTM A307 Grade A Hex Bolts are standard, low-carbon steel fasteners intended for general purpose, non-structural applications where a high tensile strength is not the primary requirement. They are designed for simple connections and moderate loads, making them the most economical choice for general manufacturing, maintenance, and utility uses. We supply these bolts with various finishes, most commonly zinc plating, to provide basic corrosion resistance for indoor or sheltered outdoor environments.

Key Use

General Purpose, Non-Critical Applications

Applications

  • General Assembly: Used in the manufacture of shelving, furniture, and light machinery.

  • Anchoring Light Fixtures: Used for non-load bearing attachments in concrete or masonry (with sleeves).

  • Maintenance and Repair: Common replacement fastener for non-structural connections.

  • Utility Pole Hardware: Used for attaching brackets and signs where loading is moderate.

Advantages

  • Cost-Effective: The most economical bolt option for non-critical fastening needs.

  • Versatile: Available in a vast range of sizes and lengths, compatible with standard hex nuts.

  • Easy Installation: Can be installed with common hand tools and does not require specialized torque procedures.

  • Weldable: Low carbon content makes the base material readily weldable for fabrication.

Payment & Shipping

We offer large-volume production runs and accept TT payment against shipping documents. A307 bolts are typically shipped in bulk sacks or durable fiber drums, optimized for high-density container loading to minimize freight costs for commodity buyers.

FAQ

  • Q: Can I use A307 Grade A bolts in a structural steel joint?
  • A: No. A307 Grade A bolts lack the specified mechanical properties (tensile and yield strength) and testing requirements for structural joints. For structural steel, you must use ASTM A325 or A490 high-strength bolts.
  • Q: What are the typical finishes available for A307 bolts?
  • A: Most are supplied with a thin Zinc Plating (clear or yellow chromate) for indoor use. For outdoor or heavier-duty applications, Hot Dip Galvanizing (HDG) is a common, more durable coating option.
