Lock nut M3

M3 Lock Nut for Small Mechanical Assemblies

This M3 lock nut secures a matching M3 threaded fastener and helps resist loosening caused by movement or vibration. It is suitable for small brackets, enclosures, model frames and other assemblies that specify M3 hardware.

Choose it to match the screw or bolt thread in your project, allowing sufficient clearance for the nut and the installation tool.

Key Features

• M3 metric thread size.
• Lock-nut design for retaining threaded joints.
• For matching M3 screws, bolts or threaded rods.
• Useful for assembly, maintenance and mechanical prototypes.

Installation Notes

Verify the thread diameter and pitch before fitting. Start the nut straight to avoid cross-threading and ensure adequate thread engagement.

Tighten using a suitable tool and the torque required for your fastener and assembly materials. Check the finished joint for secure seating without damaging the parts being clamped.
