Heavy hex bolts are a type of fastener with a larger and thicker head compared to standard hex bolts. Designed for structural applications, they offer higher strength and load-bearing capacity, making them ideal for demanding environments like steel construction.
Unmatched Quality Assurance
We follow ISO9001:2015 quality management standards, ensuring every bolt meets stringent quality requirements. From raw material analysis to final inspections, we leave no room for defects.
Global Reach
Our bolts are trusted by industries in North America, Europe, Australia, Russia, Southeast Asia, and the Middle East. With a 15,000 sqm factory and a monthly production capacity of 2,000 tons, we can handle orders of any scale.
Customization at Its Best
We understand that every project has unique requirements. That’s why we offer custom designs, finishes, and packaging to meet your exact needs.
Our manufacturing process ensures precision at every step:
Material Selection: We use premium carbon steel or alloy steel for durability.
Forging: Bolts are Forged and heat treatment to achieve the desired shape and strength.
Threading: Threads are machined to exact specifications for reliable connections.
Finishing: Various coatings are applied, such as H.D.G.,black for added protection.
Quality Checks: Each batch undergoes testing for tensile strength, corrosion resistance, and dimensional accuracy.
Material Composition: A325 bolts are made from medium carbon steel, while A490 bolts use alloy steel for higher tensile strength.
Applications: A325 bolts are commonly used in structural steel connections, whereas A490 bolts are preferred for higher load-bearing requirements.
Finish Options: A490 bolts are not available in hot-dip galvanized coatings due to hydrogen embrittlement concerns.
To select the best heavy hex bolts for your application:
Consider Load Requirements: For heavy-load applications, choose A490 bolts.
Evaluate Environmental Conditions: Use coated bolts for corrosive environments.
Match Specifications: Ensure the bolts meet relevant ASTM or ISO standards for compatibility.
We combine advanced technology, robust quality systems, and a customer-first ethos to deliver the best heavy hex bolts for every project. Partner with us to experience unmatched reliability and expertise.
Heavy hex bolts are versatile and widely used in:
Structural Steel Construction: Securely connecting beams and columns.
Machinery: Ensuring stability in high-stress environments.
Bridges: Providing critical support in suspension and beam bridges.
Industrial Equipment: Enhancing the durability of heavy-duty equipment.
