TENSION CONTROL BOLTS (S10T BOLTS)
What are S10T Tension Control Bolts?
S10T Tension Control Bolts, also known as S10T shear bolts, are high-strength fasteners designed for applications requiring significant load-bearing capacity and durability. These bolts are commonly used in steel structures, transportation infrastructure, and other heavy-duty constructions. Unlike conventional high-strength hex bolts, S10T bolts have a distinct design and are specifically used in connections that require high tensile strength.
At Quang Thai, our S10T Tension Control Bolts are manufactured following the Japanese JSS II 90 - 1996 standard, ensuring superior quality and performance.
Key Features of S10T Tension Control Bolts
Structure and Components
An S10T Tension Control Bolt consists of five main components:
• Bolt head: Designed with a round, domed shape, which serves as the main load-bearing component.
• Shank: A cylindrical body with a partially threaded section. The threads follow the metric system, the most commonly used standard in Vietnam.
• Shear section: This unique feature differentiates S10T bolts from other high-strength bolts. It is designed to break off when a specialized power wrench tightens the nut onto the bolt. This mechanism prevents bolt rotation during tightening, ensuring a secure and reliable connection.
• Nut: Provided with the bolt for secure fastening.
• Washer: Included to enhance stability and load distribution.
Material Composition
S10T Tension Control Bolts from Quang Thai are made from high-strength materials, typically incorporating chromium and manganese for added durability. Common steel grades used in manufacturing include SCM435, 40Cr, and 21ATBA, ensuring excellent mechanical properties.
Size and Standards
Our S10T bolts are produced in accordance with the Japanese JSS II 90 - 1996 standard, guaranteeing consistency and reliability.
Surface Treatment Options
At Quang Thai, S10T bolts undergo various surface treatments to enhance their performance and longevity:
• Hot-dip galvanizing
• Electro-galvanizing (white-blue, gray, and yellow zinc plating)
• Dacromet and Geomet coatings
• Black oxide coating
Due to their high strength, S10T bolts are not commonly hot-dip or electro-galvanized, as the hydrogen involved in these processes can compromise the toughness of steel, leading to potential cracking. Therefore, Geomet, Dacromet coatings, or black oxide treatments are preferred for optimal performance.
Advantages and Disadvantages of S10T Tension Control Bolts
Advantages
• High Strength: As high-strength fasteners, S10T bolts offer excellent load-bearing capacity and durability, making them suitable for harsh environments.
• Self-Shearing Mechanism: Enhances the tightening process, ensuring a secure connection and eliminating the risk of bolt rotation.
• Easy Installation: Only requires a specialized power wrench to tighten, eliminating the need to hold the bolt head, making installation more efficient, especially in difficult-to-reach areas.
Disadvantages
• Single-Use: Once installed, the shear section breaks off, preventing reuse. S10T bolts are designed for one-time application only.
Applications of S10T Tension Control Bolts
• Steel structures: Used for assembling warehouses, factories, bridges, ports, and other load-bearing steel structures.
• Railway construction: Frequently applied in railway systems due to their excellent resistance to dynamic loads.
• Easy installation in challenging locations: The self-shearing feature allows for quick and silent installation, even in confined spaces, with minimal manpower requirements.
• Aesthetic and compact applications: Used in certain machinery and equipment where a clean, streamlined appearance is desired.
