• Integrated flange design eliminates the need for separate washers, simplifying assembly and reducing component count
• Precision metric coarse threading (M12x1.75) ensures quick installation and secure fastening in various materials
• Rockwell C22 hardness provides excellent wear resistance and durability under mechanical stress
• External hex drive offers superior torque transmission and compatibility with standard industrial tools
• Partial threading allows for optimal clamp force distribution and vibration resistance in structural applications

Professional Applications & Engineering Value

This M12 hex head screw delivers exceptional engineering value through its Class 8.8 strength grade and zinc yellow-chromate plated steel construction, specifically designed to address common industrial challenges. The DIN 6921 flange provides distributed bearing pressure, preventing surface damage and maintaining joint integrity in high-vibration environments like machinery assembly, structural steel connections, and automotive frameworks. The metric coarse thread (1.75mm pitch) ensures rapid installation while maintaining ISO 898-1 compliance, making it ideal for production lines where speed and reliability are critical. With 110,000 PSI tensile strength and corrosion-resistant coating, this fastener solves durability concerns in outdoor equipment, manufacturing fixtures, and construction applications where exposure to elements and heavy loads would compromise ordinary fasteners.

Specification Summary & Compliance

This hex head screw features M12x1.75 metric coarse threads with Class 6g thread fit tolerance for precise engagement. Manufacturing complies with ISO 898-1 mechanical properties standard and DIN 6921 dimensional specifications for flange head screws. The 45mm length with 30mm minimum thread length provides optimal clamping range. Materials and plating meet RoHS and REACH environmental compliance requirements for industrial use.
