ASTM A325 BOLTS
What is an ASTM A325 Bolt?
ASTM A325 bolts are high-strength structural bolts manufactured in Vietnam by Quang Thai, adhering to the ASTM standards set by the United States. These bolts feature a hexagonal head and a partially threaded body, made from high-strength steel for reliable performance in various industrial applications.
At Quang Thai, our A325 bolts are produced in-house with full certification and quality assurance. We are committed to delivering top-quality ASTM A325 bolts at the most competitive prices on the market.
Features of A325 Bolts
Material:
• Type 1: Medium carbon steel, alloy steel
• Type 3: Weathering steel (Corten steel)
Size: Quang Thai manufactures ASTM A325 bolts with diameters ranging from 5/8" to 1-1/2", following the dimensional standards of ASME B18.2.6 - 2010.
Mechanical Properties: Due to varying industry requirements in Vietnam, A325 bolts are available in both Inch and Metric systems (A325M). Each bolt undergoes rigorous quality checks according to the respective system’s standards.
Surface Treatments: Common surface treatments for A325 and A325M bolts include:
• Hot-dip galvanizing
• Black oxide coating
• Electro-galvanizing
• Geomet or Dacromet coating (available upon request)
Applications of ASTM A325 Bolts
A325 bolts are widely used in industries requiring high load capacity, safety, and durability, including:
• Steel structures: Industrial zones, factories
• Energy sector: Wind turbines, hydroelectric plants
• Oil & gas, marine construction: Offshore platforms, ports
• Civil engineering projects: Bridges, highways, infrastructure
• Heavy machinery: Equipment assembly and structural connections
Pricing of ASTM A325 Bolts
The cost of A325 bolts varies based on several factors:
• Type: Different categories of A325 bolts have distinct pricing. For example, heavy-duty A325 bolts are more expensive than standard A325 bolts, and fully threaded A325T bolts cost more than partially threaded A325/A325M bolts.
• Size: Larger diameters and lengths come at a higher price. For example, an A325 M42 bolt costs more than an M39, and an A325 M20x120 is priced higher than an M20x100.
• Surface treatment: The finishing process also affects pricing. Hot-dip galvanized bolts, known for superior corrosion resistance, are more expensive than electro-galvanized ones.
