The Combination Locking Nut Kit M3*8-20 is a versatile M3 Threaded Fastener Set Locking designed for secure fastening in high-vibration environments. This Combination Nut Set M3 Fastener includes M3 nuts in sizes ranging from 8mm to 20mm thread length, manufactured from corrosion-resistant stainless steel with a zinc-plated finish. Operating within a temperature range of -40°C to +120°C, the kit features integrated nylon locking inserts or pre-applied thread-locking adhesive for vibration-resistant performance. Ideal for automotive, aerospace, electronics, and industrial machinery applications, these self-locking nuts eliminate the need for secondary retention components. The set offers tool-free installation compatibility with standard M3 screwdrivers or wrenches, with torque ratings up to 4.5 Nm. Key advantages include reusability up to 10 cycles, consistent clamping force retention, and protection against galvanic corrosion.
