Key Features & Benefits at a Glance
- Exceptional corrosion protection with black-phosphate steel coating, extending service life in harsh industrial environments
- Superior load-bearing capacity with Class 10.9 strength grade and 150,000 psi tensile strength for heavy-duty applications
- Enhanced stability and load distribution through integrated 35 mm flange, eliminating the need for separate washers
- Reliable thread engagement with M16 coarse pitch (2 mm) and Class 6g fit, ensuring quick assembly and vibration resistance
- Optimized torque transmission via external hex drive and 24 mm head width, preventing tool slippage during installation
- Consistent mechanical performance with Rockwell C32 hardness, maintaining integrity under repeated stress
- Full-threaded design providing maximum grip length and uniform clamping force across the entire 50 mm length
Professional Applications & Engineering Value
This M16 hex head screw delivers critical engineering advantages for industrial assemblies requiring high tensile strength and corrosion resistance. The black-phosphate steel coating creates a protective barrier against oxidation and chemical exposure, making it ideal for outdoor construction, machinery frames, and automotive components exposed to moisture. The flanged design distributes clamping pressure over a wider surface area (35 mm diameter), reducing point stress and preventing material deformation in sheet metal or structural joints. With Class 10.9 strength and coarse metric threading, it maintains secure fastening in high-vibration environments while allowing rapid installation with standard hex tools. These features collectively address common failure points in heavy equipment, ensuring long-term reliability and reduced maintenance cycles.
Specification Summary & Compliance
Manufactured to ASME B18.2.3M dimensional standards with Class 6g thread tolerance for precise fit. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Meets SAE J1199 specifications for mechanical properties and material quality.
