Key Features & Benefits at a Glance
- Exceptional Tensile Strength: Class 10.9 rating with 140,000 psi tensile strength ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
- Superior Corrosion Resistance: Black-oxide coating on alloy steel provides enhanced protection against rust and wear, extending service life in harsh industrial environments.
- Optimized Thread Design: Fully threaded M6 coarse (1 mm pitch) with Class 6g fit offers quick, secure installation and consistent clamping force.
- High Hardness & Durability: Rockwell C32 hardness maintains structural integrity and resists deformation during repeated use.
- Efficient Hex Drive: 4 mm hex drive allows for easy, high-torque installation with standard tools, minimizing assembly time.
- Standardized Rounded Head: Button head profile (ISO 7380) ensures a low-profile, flush fit while distributing load evenly.
- Compliance Assurance: Meets ISO 7380, RoHS 3, and REACH standards, guaranteeing safety and regulatory adherence for global supply chains.
Professional Applications & Engineering Value
This M6 hex button head screw is engineered to address critical fastening challenges in demanding sectors like machinery, automotive, and heavy equipment. The black-oxide alloy steel construction combats corrosion in humid or abrasive settings, while the Class 10.9 strength and Rockwell C32 hardness prevent stripping and fatigue under dynamic loads. The fully threaded coarse pitch design enables rapid engagement and vibration resistance, ideal for assembly lines requiring speed and reliability. Compliant with ISO 7380, it ensures interchangeability and precision in metric screw applications, reducing downtime and maintenance costs.
Specification Summary & Compliance
This fastener adheres to ISO 7380 for dimensional accuracy, with M6 x 1 mm coarse thread and Class 6g thread fit tolerances. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental safety, alongside Class 10.9 mechanical properties as per international standards.
