Key Features & Benefits at a Glance
- Superior tensile strength with 110,000 psi rating for reliable performance in high-stress applications
- Left-hand threading provides secure fastening in applications where right-hand threads would naturally loosen
- Class 8.8 strength grade ensures consistent mechanical properties and load-bearing capacity
- Fully threaded design offers maximum grip length and uniform stress distribution
- External hex drive enables easy installation with standard tools and high torque application
- Rockwell C21 hardness provides excellent wear resistance and durability
- Coarse 1mm pitch threading allows for quick assembly and reduced cross-threading risks
Professional Applications & Engineering Value
These M6 left hand hex head screws are engineered to solve critical fastening challenges in industrial environments where reverse-thread applications prevent accidental loosening from rotational forces. The Class 8.8 steel construction combined with Rockwell C21 hardness ensures reliable performance in machinery, equipment, and assemblies subjected to vibration and dynamic loads. The metric coarse thread with 1mm pitch provides rapid installation while maintaining secure fastening in materials where fine threads might strip. These left hand threaded fasteners are particularly valuable in rotating equipment, conveyor systems, and specialized machinery where standard right-hand threads would compromise safety and operational integrity.
Specification Summary & Compliance
This M6x1mm hex head screw features Class 6g thread fit tolerance for precision mating with standard nuts and threaded holes. Manufactured to ASME B18.2.3M and ISO 898-1 specifications, ensuring dimensional accuracy and mechanical properties. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict material restrictions.
