Metric Size Grade 10.9 Hex Head Cap Screw
Metric Size Grade 10.9 Hex Head Cap Screws: High-Strength Fastening for Demanding Industrial Applications
The Metric Size Grade 10.9 Hex Head Cap Screw is designed for superior strength, precision, and reliability in high-stress mechanical and structural applications. Manufactured to meet ISO 898-1 and DIN 933/931 standards, these fasteners deliver exceptional tensile and yield strength, making them ideal for heavy-duty machinery, automotive, and construction environments.
Produced from medium carbon alloy steel, each Grade 10.9 hex head cap screw is quenched and tempered to achieve a tensile strength of 1,040 MPa (approximately 150,000 psi) and a yield strength of 940 MPa (around 136,000 psi). This combination of hardness and toughness allows these screws to withstand vibration, torque, and extreme mechanical stress without deformation or failure.
The hexagonal head design ensures efficient wrenching and precise torque control, providing a tight, secure fit that resists loosening under dynamic loads. Available in both coarse and fine thread pitches, Grade 10.9 screws offer compatibility across a wide range of industrial components and assemblies.
To enhance corrosion resistance and appearance, these screws are available in zinc-plated, black oxide, or phosphate finishes, providing protection in both indoor and outdoor environments. Whether used in automotive suspensions, heavy machinery, or structural frameworks, they deliver consistent performance and durability where strength matters most.
