M6 Hex Flange Lock Nut, Grade 10 Blue Zinc Plated Steel

M6 hexagon flange nut with a built-in clamping piece that grips the bolt thread, so it resists working loose under vibration. Use it on M6 bolts in heavy-lift and agricultural drone frames, such as arm clamps, landing gear and payload brackets, wherever a plain nut could back off.

Key features

• Integrated flange spreads the clamping load over a wider area, so no separate washer is needed
• Property class 10 nut, the grade matched to 10.9 high-strength bolts
• Blue passivated zinc plating protects against corrosion from rain, dew and spray chemicals
• Standard M6 hex takes a 10 mm spanner or socket

Prevailing-torque nuts lose some grip each time they are removed, so fit a fresh nut on critical joints such as arm clamps after repeated disassembly.
