S-97760A212 M6 x 12 mm ASME B18.2.3.1M, ISO 898-1 Left-Hand Threaded Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with Class 8.8 rating (110,000 PSI) ensures reliable performance under high-stress industrial applications
• Left-hand threading provides secure fastening in applications where right-hand threads might loosen due to rotational forces
• Coarse 1mm thread pitch enables quicker installation and better resistance to vibration-induced loosening
• External hex drive design allows for high torque application using standard tools for efficient assembly and disassembly
• Full threading along the 12mm length provides maximum grip and load distribution across the entire fastener
• Rockwell C21 hardness ensures superior wear resistance and maintains thread integrity through repeated use
• Comprehensive compliance with international standards guarantees consistent quality and interchangeability

Professional Applications & Engineering Value

This M6 left-hand hex head screw delivers critical engineering solutions where conventional right-hand threads would compromise safety. The Class 8.8 steel construction provides optimal strength-to-weight ratio for demanding applications in machinery, automotive systems, and industrial equipment. The coarse metric thread with 1mm pitch offers superior performance in materials where fine threads might strip, while the external hex drive accommodates high-torque installation without cam-out issues. These fully threaded fasteners maintain consistent clamping force in vibration-prone environments, making them ideal for rotating assemblies, conveyor systems, and equipment subject to reverse torque conditions. The combination of left-hand threading and high tensile strength creates a reliable fastening solution that prevents accidental loosening in critical applications.
