Understanding the S10T Torque Shear Bolt: A Comprehensive Guide

JSS II-09 S10T Torque Shear Bolt

Introduction

    In the world of construction and engineering, the S10T Torque Shear Bolt stands out as a crucial component. If we are looking at the large structure such as building or bridge, S10T bolt could be one of the most seen fasteners.
   

    It is known for its high strength and reliability; this bolt is widely used in structural applications. In this post, we will explain its features, benefits, and applications of the S10T Torque Shear Bolt.

There are similar calling terms for S10T Bolt, such as TC Bolt (Tension control bolt) and Twist-off Bolt as well.

What is an S10T Torque Shear Bolt?

    The S10T Torque Shear Bolt is a type of tension control bolt designed for high-strength applications. It consists of a round head bolt, a nut, and a washer, and is known for its unique installation process that ensures precise tensioning.

S10T is stand for

S = Structural

10 = 1,000 N/mm²

T = Tensile Strength

If we combined all of the definitions of S10T Bolt, we can summarize that this is a Bolt used for structural work that can handle Tensile Strength up to 1,000 N/mm².

    S10T Bolt is mostly use for structural work such as building or bridge, as characteristic of this bolt design for this purpose.
When it is fastened with shear wrench and reached optimum torque, spline (tip of the bolt) will be teared. This is to ensure that right torque is fastened to this bolt preventing risk of installation in term of over or under-tightening.

    This pintail will naturally break when the bolt is tightened to the specified torque. When you see the broken pintail, it is immediately clear that the bolt has been fully tightened. This property prevents you from forgetting to tighten the bolt and allows for proper torque management
    Also, from a user's perspective, shear bolts are more efficient to work with than hex bolts because they do not require precise torque adjustments.

Key Features

High Strength: The S10T Torque Shear Bolt is made from high-grade wire rod specially added by Cr, Mn, Ni, and B to obtain most stabilized chemical compound along with proper heat-treatment process to gain best mechanical property and providing exceptional tensile strength.
Installation with no worry of over or under-tension: The bolt is designed to be installed using a shear wrench, which ensures that the bolt is tightened to the correct tension.
Reliability: Once installed, the bolt provides a secure and reliable connection, making it ideal for critical structural applications.

Benefits of Using S10T Torque Shear Bolts

Consistent Tensioning: The use of a shear wrench ensures that each bolt is tightened to the same tension, reducing the risk of over or under-tightening.
Time Efficiency: The installation process is quick and straightforward, saving time on construction projects. With a proper tool, installation speed will be greatly increased.
Durability: These bolts are designed to withstand harsh conditions, providing long-term reliability.
Applications

The S10T Torque Shear Bolt is commonly used in:

Steel Structures: Ideal for connecting steel beams and columns.
Bridges: Used in the construction of bridges due to its high strength and reliability.
Industrial Buildings: Ensures the stability and safety of large industrial structures.

Installation Process

1. Preparation: Ensure all components such as S10T bolt (A bolt set of round head bolt, nut, washer) and shear wrench (installation tool) are ready.
2. Initial Tightening: First tightening is the process of applying a specified torque to a bolt that has been hand-tightened to bring the bolt and the component into close contact. As this is not final tightening, the pintail will not break at this stage.

3. Marking: In actual work sites, the bolts are marked once the initial tightening is completed. This is an essential step to prevent co-rotation (the bolt and nut, or bolt and washer rotating together, resulting in incomplete tightening). After final tightening, if the misalignment of the markings is within the tolerance range, it is proof that the tightening process was done correctly.
4. Final Tightening: After the initial tightening, change the shear wrench and perform the final tightening. As mentioned above, when the specified torque is reached, the pintail will break, so you can visually check that the tightening is complete.

Conclusion

    The S10T Torque Shear Bolt is an essential component in modern construction, offering high strength, reliability, and effortless of installation. Whether you’re working on a steel structure, bridge, or industrial building, these bolts provide the security and durability needed for critical connections.
