Key Features & Advantages
- Metal locking section-upper threads are deformed to grip the bolt, creating prevailing torque against vibration. No nylon to wear out or soften.
- High-temperature service-the reason to choose all-metal: no nylon insert, so it holds where standard nylon-insert nuts fail (nylon is typically limited to ~120°C; metal lock nuts commonly rated to 300°C and above, depending on grade).
- Class 8 or 10 carbon steel, A2/A4 stainless -pair the nut class with the bolt: Class 8 with 8.8, Class 10 with 10.9.
- Finish options-zinc plating (5–8μm), black oxide (dry indoor), hot-dip galvanizing (40–80μm, outdoor), plain where specified.
- Metric threads -coarse and fine pitches; fine must be specified as it won't interchange with coarse.
