HEADLESS STUD BOLTS
What Are Headless Stud Bolts?
Headless stud bolts, also known as straight anchor bolts, play a crucial role in securing structural components, especially in steel constructions. These bolts are primarily used to connect concrete foundations to structural elements, making them indispensable in various industries, including electrical systems, transformer stations, factories, and even nuclear power plants.
Key Features of Headless Stud Bolts
Materials
At Quang Thai, our headless stud bolts are manufactured using high-quality materials, including:
• Carbon Steel: S45C, C45, CT3
• Alloy Steel: 40Cr, 40CrMn
• Stainless Steel: SUS 201, SUS 304, SUS 316
Manufacturing Standards
We produce headless stud bolts according to international standards such as ASTM F1554 (ASME B 18.31.5), JIS, DIN, and ISO. Additionally, we offer custom manufacturing for headless anchor bolts ranging from M16 to M80, based on project-specific requirements and technical drawings.
Surface Treatments
Since one end of the bolt is embedded in concrete while the other end is used for fastening, different surface coatings are available, including:
• Black oxide coating
• PTFE coating
• Hot-dip galvanizing
• Electro-galvanizing
• Geomet and Dacromet coatings
Applications of Headless Stud Bolts
Headless stud bolts are widely used in construction, electrical systems, and mechanical engineering:
• Factories and Pre-engineered Steel Buildings: Used to anchor steel column bases to concrete foundations, ensuring structural stability.
• Street Lighting and Utility Poles: Essential for securing light poles and electrical poles to concrete bases, preventing movement and ensuring safety.
• Machine Bases and Equipment Installation: Helps stabilize machinery, reducing vibrations and preventing operational misalignment.
• Port Cranes and Dock Structures: Used in seaport infrastructure to anchor cranes, hoists, and mooring points securely.
Pricing Factors for Headless Stud Bolts
The cost of headless stud bolts varies based on several factors:
• Size: Larger diameters and longer bolts are priced higher. For example, M42 bolts cost more than M39, and M20x120 is more expensive than M20x100.
• Strength Grade: Higher-grade bolts have a higher price. For example, Grade 8.8 bolts cost more than Grade 6.6 or 4.6.
• Manufacturing Standards: Different standards have varying mechanical properties, strength grades, and materials, affecting the price.
• Bolt Type: Double-threaded bolts are typically more expensive than single-threaded ones.
• Surface Coating: Prices vary depending on the coating type. For instance, hot-dip galvanizing is more costly than electro-galvanizing due to its enhanced durability.
