• High hardness rating (Rockwell C32) provides excellent wear resistance and durability under repetitive loads.
• Precision Class 6h thread fit guarantees smooth assembly and secure fastening, reducing installation time and improving joint integrity.
• Partially threaded design allows for controlled clamping force and optimal load distribution in structural applications.
• Coarse thread pitch enables quick installation and superior resistance to vibration loosening in dynamic equipment.
• ISO 4014/DIN 931 certification ensures dimensional accuracy and interchangeability, providing reliable compliance for global engineering projects.

Professional Applications & Engineering Value

These Class 10.9 hex head screws deliver critical engineering value in heavy machinery, construction, and automotive assemblies where high tensile strength and corrosion resistance are paramount. The M10 coarse thread with 1.5 mm pitch provides excellent engagement in various materials, while the partially threaded shank design prevents over-tightening and distributes stress efficiently. Manufactured from high-grade steel and finished with zinc yellow-chromate plating, these fasteners withstand corrosive environments and repetitive dynamic loads, solving common industrial pain points like joint failure and maintenance downtime. The external hex drive ensures easy installation with standard tools, making them ideal for time-sensitive production lines and structural applications requiring ISO 4014/DIN 931 compliance.

Specification Summary & Compliance

This M10 x 85mm hex head screw features Class 6h thread fit per metric standards, ensuring precise dimensional accuracy. The partially threaded design provides a 26 mm minimum thread length with coarse spacing (1.5 mm pitch). Manufactured to meet ISO 4014/DIN 931 specifications, it complies with international mechanical and dimensional requirements. The zinc yellow-chromate plating offers RoHS and REACH compliant corrosion protection, while the Class 10.9 strength grade confirms adherence to high-performance fastener standards for industrial applications.
