Product Description

The Combination Lock Nut Sets (M3 Threaded Fastener Kit) includes Hex Locking Nuts M3-12 to M3-20, designed for high-vibration resistance in industrial applications such as automotive, machinery, and aerospace. These stainless steel nuts feature a hex design for easy torque application and integrate a locking mechanism (nylon insert or metal deformation) to prevent loosening under extreme conditions. With an operational temperature range of -40°C to +120°C, they offer corrosion resistance and compatibility with M3 threaded rods or bolts. The kit provides 10-20 nuts per set, ensuring secure fastening in confined spaces. Advantages include durability, reusable design (where applicable), and compliance with ISO standards. Limitations include limited chemical resistance to aggressive solvents. Ideal for motor assembly, conveyor systems, and precision equipment.
