High Tensile Bolts Manufacturer
High Tensile Bolts Manufacturer in West Bengal, Bihar & Odisha
High tensile bolts is a type of fastener designed to withstand high levels of tension or stress without breaking or deforming. These bolts are made from materials with superior strength, such as alloy steels, and are heat-treated to enhance their tensile strength. The “high tensile” designation refers to the bolt’s ability to endure significant pulling (tensile) forces before failing. We are wild range of High tensile bolts manufacturer in Kolkata, West Bengal, Odisha, Bihar. Additionally, we are reputed High tensile bolts manufacturer in Chhattisgarh, Jharkhand.
These bolts are commonly used in heavy-duty applications such as structural steelwork, construction machinery, and automotive assemblies, where high strength and durability are crucial. However, despite their high strength, they’re not suitable for environments with extreme corrosion or high temperatures, as their mechanical properties can degrade under those conditions.
Key Characteristics of High Tensile Bolts:
- Material: Typically made from alloy steel or carbon steel, these bolts are heat-treated or processed to increase their tensile strength. Common materials include 8.8 & 10.9 grades of steel, which indicate their tensile strength.
- Tensile Strength: The tensile strength of a bolt refers to the maximum stress it can withstand before failing (breaking or deforming). For example, a Grade 8.8 bolt has a tensile strength of approximately 800 MPa (megapascals), while a Grade 12.9 bolt can have a tensile strength of up to 1,200 MPa.
- Applications: High tensile bolts are often used in:
- Construction (steel structures, bridges, buildings)
- Automotive industry (engine components, suspension systems)
- Heavy machinery (mining equipment, industrial machinery)
- Aerospace (aircraft components)
- Thread Types: High tensile bolts come in various thread types, such as coarse threads, fine threads, and others, depending on the application requirements.
- Corrosion Resistance: Some high tensile bolts are coated (e.g., galvanized, zinc-plated) to improve their corrosion resistance, especially in outdoor or marine environments.
- Strength Grades: High tensile bolts are classified by their strength grade, which is typically indicated by a number printed on the head of the bolt. These grades are internationally standardized:
- Grade 8.8: Medium tensile steel, good for general use.
- Grade 10.9: Higher strength, used for more demanding applications.
- Torque and Tightening: High tensile bolts require precise torque settings during installation to ensure the proper clamping force and to prevent damage to the bolt or the surrounding material.
Grade 8.8
Krishna Enterprise 8.8 grade hex bolts are high-strength fasteners crafted from medium carbon steel that undergoes a quenching and tempering process to enhance their mechanical properties. The designation “8.8” signifies their impressive tensile strength of 800 MPa and yield strength of 640 MPa, making them well-suited for demanding applications where robustness and reliability are crucial. These bolts are engineered to withstand significant loads and stresses, ensuring secure connections in various structural and mechanical settings. Their hexagonal head design facilitates easy installation and removal, making them a preferred choice in construction, automotive, and heavy machinery applications.
The Indian Standard for 8.8 grade Mechanical and technical specifications of bolts falls under IS – 1367, specifically in the section that covers high-strength fasteners. More precisely, it can be referenced in:
IS 1367 (Part 3):
- And dimensional specifications are covered under Indian Standard (IS) – IS – 1363/1364.
- These are made from raw material from the prime producers only,
Grade 10.9
10.9 grade hex bolts from KRISHNA ENTERPRISE are high-strength fasteners meticulously crafted from medium carbon steel, which undergoes a precise heat treatment process to enhance their mechanical properties. The designation “10.9” indicates that these bolts possess an impressive minimum tensile strength of 1000 MPa (megapascals) and a yield strength of 900 MPa, making them exceptionally suitable for demanding applications that require robust performance and reliability. Designed with a hexagonal head for easy installation and removal using standard wrenches, these bolts ensure secure connections in various environments, including construction, automotive, and heavy machinery applications. Their ability to withstand significant loads and stresses underscores their importance in critical structural and mechanical settings. Again These are made from raw material from Prime producers only.
Advantages of Using High Tensile Bolts
- Safety and Performance:
High tensile bolts are designed to maintain clamping force under load, reducing the likelihood of bolt failure. This makes them highly reliable in critical applications, ensuring safety in machinery and infrastructure projects. - Ease of Installation:
Thanks to their standardized dimensions and thread forms, High Tensile Bolts are easy to install and work with. They can be used with various nuts and washers to ensure a secure and tight fit. - Cost-Effective:
While they offer excellent strength, High Tenisle bolts are often more affordable compared to higher-grade bolts, such as Grade 10.9, making them a cost-effective choice for projects where high strength is needed but cost is a consideration. - Long-Term Reliability:
Their durability under stress and resistance to deformation means High Tensile Bolt offer long-term performance with minimal maintenance. This can lead to reduced downtime and lower maintenance costs over time.
Conclusion
High tensile bolts are an essential fastener solution for a variety of industries that require strength, durability, and reliability. From construction to automotive assembly, their robust mechanical properties make them the go-to choice for heavy-duty applications. If you need a fastener that can withstand stress and provide consistent performance, high tensile bolts are a top choice for your next project.
