High Tensile Grade 10.9 Fasteners

Product Description

High Tensile Grade 10.9 fasteners offer superior strength, durability, and corrosion resistance, making them ideal for demanding industrial, automotive, and construction applications. Their high performance and reliability deliver safer, longer-lasting joint integrity in critical assemblies.

Key Benefits

Exceptional tensile strength of approximately 1000 MPa enables Grade 10.9 fasteners to handle high load and mechanical stress environments.

Excellent resistance to wear, fatigue, and vibration ensures safe operation even under dynamic loads and high-impact scenarios.

Enhanced temperature resistance (up to 150C) and improved corrosion resistance can be further increased with protective coatings such as zinc plating or galvanization.

Reliable joint integrity with reduced risk of loosening or failure, thanks to optimized hardness through quenching and tempering processes.

Typical Applications

Widely utilized in automotive suspension systems, engines, and machine parts due to their ability to withstand high mechanical loads.

Common in heavy machinery, construction, and pressure vessel assemblies where superior performance is mandatory.

Favored for use in demanding sectors like robotics, aerospace structures, turbines, and power generation equipment.

Suitable for marine, chemical, and offshore environments when coated for enhanced corrosion resistance.

Usage & Installation Steps

Ensure proper selection of diameter and length based on load and application requirements; available sizes range from M4 to M100 and more.

Install using calibrated torque tools to prevent over-tightening or under-tightening, critical for maintaining safety and performance in dynamic assemblies.

Use with compatible Class 10.9 nuts and washers to optimize joint strength and reliability.

Coat with anti-corrosive finishes or oils for outdoor, marine, or corrosive atmospheres to prolong service life.
