Professional Applications & Engineering Value

Engineered for demanding industrial settings, this M8 metric hex screw combines black-oxide alloy steel construction with a Class 10.9 strength rating to address critical challenges like joint loosening under dynamic loads. The fully threaded coarse pitch design enhances grip in soft materials and resists vibrational loosening, making it ideal for machinery, automotive assemblies, and structural frameworks. Its corrosion-resistant coating ensures long-term reliability in humid or chemically exposed environments, while the rounded head and 5mm hex drive facilitate quick installation in tight spaces, reducing labor costs and maintenance downtime.

Specification Summary & Compliance

This fastener adheres to ISO 7380 standards with Class 6g thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory acceptance in global markets. The Rockwell C32 hardness and 140,000 PSI tensile strength validate its performance for high-stress applications.
