Key Features & Benefits at a Glance
- Maximum Load-Bearing Capacity: Class 10.9 strength grade and 150,000 psi tensile strength ensure reliable performance under extreme mechanical stress.
- Superior Durability & Wear Resistance: Rockwell C32 hardness provides excellent resistance to deformation and wear in demanding industrial environments. li>Precision Thread Fit for Secure Assembly: Class 6g thread fit guarantees consistent, vibration-resistant connections with reduced risk of loosening.
- Optimized for High-Torque Applications: External hex drive and 22mm head width allow for easy installation with standard tools, even in high-torque scenarios.
- Versatile Partial Threading Design: 34mm minimum thread length on a 90mm shank provides flexibility for applications requiring both clamped and unthreaded sections.
- Global Standard Compliance: Manufactured to DIN 931 and ISO 4014 specifications, ensuring interchangeability and reliability in international projects.
- Environmentally Responsible Manufacturing: RoHS 3 and REACH compliance supports sustainable procurement and safe use in regulated industries.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M14 hex head screw delivers exceptional clamping force and fatigue resistance in machinery, structural steel connections, and automotive assemblies. The Class 10.9 steel construction, combined with a coarse metric thread (2mm pitch), ensures rapid installation and high vibration resistance, reducing maintenance downtime. Its partially threaded design allows precise load distribution—ideal for scenarios where unthreaded shank sections must bear shear loads. With an external hex drive and standardized dimensions per DIN 931/ISO 4014, it integrates seamlessly into existing metric fastener systems, providing engineers with a reliable, specification-compliant solution for critical joints.
Specification Summary & Compliance
This fastener features M14 x 2mm coarse threads with Class 6g tolerance for precise fit, and a 90mm length with 34mm minimum thread length. It conforms to ISO 4014 and DIN 931 manufacturing standards, and is verified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant for environmental safety.
