Metric Size Grade 10.9 Hex Head Cap Screw
Metric Size Grade 10.9 Hex Head Cap Screws for High-Stress Applications
Metric Size Grade 10.9 Hex Head Cap Screws are engineered to provide exceptional strength, precision, and long-term reliability in demanding industrial environments. Designed to meet strict international standards, these fasteners are widely specified for applications where high clamping force, resistance to vibration, and structural integrity are essential.
Engineered to International Performance Standards
Manufactured in accordance with ISO 898-1 and DIN 933 / DIN 931 specifications, Grade 10.9 hex head cap screws are produced from quenched and tempered medium carbon alloy steel. This process delivers a minimum tensile strength of 1,040 MPa and a yield strength of 940 MPa, allowing these fasteners to perform reliably under extreme mechanical stress. Their strength-to-ductility balance makes them ideal for assemblies subjected to dynamic loading, torque, and shock.
Hex Head Design for Precision Torque Control
The six-sided hex head design ensures efficient wrench or socket engagement, allowing for accurate torque application and consistent preload. This reduces the risk of loosening under vibration and helps maintain joint integrity in high-demand installations. Grade 10.9 hex head cap screws are available in both coarse and fine thread pitches, providing compatibility with a wide range of metric components and design requirements.
Finish Options for Environmental Protection
To suit different operating conditions, Metric Grade 10.9 hex head cap screws are offered in multiple finishes. Zinc-plated options provide corrosion resistance for moderate outdoor or humid environments, while black oxide and phosphate finishes offer improved wear resistance and a clean, professional appearance. Each finish maintains dimensional accuracy and mechanical performance.
