Product Description

The M3*30-20 Locking Nut Kits are high-precision Combination Lock Nut Fasteners designed for secure threaded assemblies in industrial applications. Each kit includes 20 sets of M3 nuts with a 30 mm thread length, featuring integrated locking mechanisms for vibration resistance and long-term stability. These Threaded Nut Assembly Sets M3 are compatible with standard M3×0.5 threaded rods or bolts, ideal for machinery, automotive, and aerospace industries requiring reliable fastening under dynamic loads. Constructed from grade 304 stainless steel, the nuts operate reliably across a temperature range of -40°C to 300°C and withstand voltages up to 500V in electrical insulation scenarios. Advantages include corrosion resistance, reusable design, and tool-free installation, though they require precise alignment during assembly. The compact nut dimensions (6 mm outer diameter, 3 mm height per unit) suit confined spaces while maintaining 15 N·m torque capacity.
