Key Features & Benefits at a Glance
- Enhanced corrosion resistance through black-oxide coating on alloy steel, extending service life in demanding environments
- Superior load-bearing capability with 140,000 psi tensile strength and Rockwell C32 hardness for high-stress applications
- Precision thread engagement with Class 5g6g fit ensuring reliable fastening and vibration resistance
- Space-saving installation thanks to ultra-low socket head profile requiring minimal clearance
- Secure torque transmission via 6mm hex drive preventing tool slippage and head stripping
- Full thread coverage along the 20mm length providing consistent clamping force distribution
- Regulatory compliance meeting RoHS 3 and REACH standards for global industrial use
Professional Applications & Engineering Value
This M14x2mm metric socket head cap screw delivers critical performance where space constraints and high mechanical stresses coexist. The black-oxide alloy steel construction resists corrosion while maintaining Rockwell C32 hardness under dynamic loads. Engineers specify these fully threaded fasteners for precision machinery, automotive assemblies, and heavy equipment where the ultra-low head profile enables flush mounting in confined spaces. The coarse thread pitch ensures rapid installation and superior resistance to vibrational loosening, while the Class 5g6g thread fit guarantees consistent clamping force in high-cycle applications. Ideal for maintenance-critical environments requiring reliable, repeatable fastening solutions.
Specification Summary & Compliance
Manufactured to metric standards with M14x2mm coarse threads and Class 5g6g thread fit per ISO specifications. Length tolerance maintained at -0.127mm to +0.127mm for precision alignment. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Right-hand thread direction with fully threaded design ensures uniform stress distribution across the entire 20mm length.
