- High-temperature performance with nylon insert maintaining locking capability up to 220°F (105°C)
- Enhanced corrosion protection with zinc yellow-chromate plating for extended service life in harsh environments
- Reliable thread engagement with Class 6H thread fit ensuring precise mating with male threads
- Heavy-duty strength classification as Class 8 for high load-bearing applications
- International compliance meeting both DIN 985 and ISO 10511 standards for global project compatibility
- Easy installation and removal with standard external hex drive design using common tools
Professional Applications & Engineering Value
These M3 nylon insert lock nuts deliver critical vibration resistance in demanding industrial applications where constant motion and shock loads compromise fastener integrity. The nylon locking element creates consistent friction against the mating thread, maintaining clamp force without damaging threads - unlike prevailing torque metal locknuts. Manufactured from zinc yellow-chromate plated steel, they provide durable corrosion protection while the Class 8 strength rating ensures reliable performance in high-stress environments. The metric coarse threading (M3 x 0.5mm) with Class 6H thread fit guarantees precise engagement in automotive assemblies, machinery frames, and industrial equipment where vibration-induced loosening could lead to catastrophic failure.
Specification Summary & Compliance
This locknut features M3 x 0.5 mm coarse metric threading with Class 6H thread tolerance for precision fit. Manufacturing complies with DIN 985 and ISO 10511 standards for dimensional accuracy and performance. The zinc yellow-chromate plating provides corrosion resistance while meeting RoHS and REACH environmental compliance. External hex design (5.5mm width, 4mm height) accommodates standard wrenching tools. Class 8 strength classification confirms high load capacity for industrial applications.
