Professional Applications & Engineering Value
Engineered for demanding industrial applications, this M6 left hand hex head screw solves critical reverse-threading needs in rotating machinery, safety mechanisms, and specialized equipment. The Class 8.8 steel construction provides reliable high tensile strength (110,000 PSI) while maintaining Rockwell C21 hardness to resist deformation under load. Zinc-plated surface treatment delivers essential corrosion protection in moist or chemically aggressive environments. The coarse 1mm pitch metric thread ensures rapid assembly and superior vibration resistance, while the external hex drive enables high-torque installation without cam-out. Ideal for maintenance applications requiring left-hand threading and industrial fasteners that must withstand dynamic loads.
Specification Summary & Compliance
This fully threaded hex head screw features M6 x 1mm metric coarse thread with Class 6h thread fit tolerance for precise engagement. Manufactured to ASME B18.2.3.1M and ISO 898-1 standards, ensuring dimensional consistency and mechanical performance. The 16mm length and external hex drive (10mm width, 4mm height) provide standardized installation compatibility. Class 8.8 strength grade verification guarantees reliable performance in industrial applications requiring certified high tensile strength fasteners.
