• High tensile strength of 110,000 psi ensures reliable performance under heavy loads and vibration
• Integrated flange design eliminates the need for separate washers, simplifying installation and reducing assembly time
• Class 8.8 strength grade provides consistent mechanical properties for critical fastening applications
• External hex drive with serrations delivers secure tool engagement and prevents slipping during torque application
• Coarse thread spacing with Class 6g fit enables quick assembly while maintaining precise thread engagement
• Full threading along 25mm length offers maximum grip and adjustment flexibility in various material thicknesses

Professional Applications & Engineering Value

These M6 hex head screws with Class 8.8 strength rating and zinc-plated steel construction address critical engineering challenges in industrial assembly. The flanged design provides distributed bearing pressure, preventing surface damage while the external hex drive ensures high torque transmission without cam-out. The coarse metric thread with 1mm pitch facilitates rapid installation in production environments, while the Rockwell C22 hardness maintains thread integrity through repeated use. Ideal for machinery, equipment manufacturing, and structural applications where DIN 6921 compliance and corrosion resistance are mandatory requirements.

Specification Summary & Compliance

Manufactured to precise Class 6g thread fit tolerances with 14.2mm flange diameter and 25mm length. Fully compliant with DIN 6921 manufacturing specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The metric coarse threading with right-hand direction ensures compatibility with standard industrial components and tooling systems.
