• Optimized thread engagement with Class 6h thread fit and coarse thread spacing ensuring secure fastening and vibration resistance
• Enhanced installation efficiency through external hex drive design and 24mm head width for easy tool access and high torque application
• Precision manufacturing according to ISO 4014/DIN 931 standards guarantees dimensional accuracy and interchangeability
• Versatile partial threading design (38mm thread length on 90mm shank) provides both threaded and unthreaded sections for specific clamping requirements
• Environmental compliance with RoHS 3 and REACH regulations ensures safe usage across various industrial sectors

Professional Applications & Engineering Value

These M16 hex head screws deliver critical engineering solutions for heavy machinery, structural steel connections, and industrial equipment assembly. The Class 10.9 steel construction provides exceptional resistance to dynamic loads and fatigue, while the Rockwell C32 hardness maintains thread integrity under repeated stress. The zinc yellow-chromate plating creates a protective barrier against corrosion in outdoor or chemically aggressive environments. With coarse thread spacing and partial threading, these fasteners prevent loosening in vibrating applications while allowing precise clamping force distribution. The external hex drive design ensures compatibility with standard tools, reducing installation time in confined spaces common in industrial maintenance and manufacturing operations.

Specification Summary & Compliance

Manufactured to ISO 4014/DIN 931 specifications with Class 6h thread fit tolerance for precise engagement. The metric coarse thread (M16x2mm) follows standardized dimensions for universal compatibility. These hex head screws feature right-hand threading and are partially threaded with minimum 38mm thread length on the 90mm shank. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial safety and sustainability requirements.
