300 Pcs AllinOne Value M3x0.5, M4x0.7 and M5x0.8 lock nuts, 100 pcs each. Buying the three sizes separately costs nearly three times as much one box covers the most common metric sizes for electronics, RC cars and 3D printers.Premium 304 A270 Stainless Steel 18 chromium and 8 nickel resists rust and corrosion in humid or outdoor conditions. The line passed ISO45001 standards, and the polished surface with clear threads never scratches your hands or workpieces.Reliable AntiLoosening The bonded nylon collar compresses against the bolt threads when tightened, creating elastic friction that keeps joints secure under vibration and temperature changes ideal for RC cars, drones, appliances and machinery.Reusable 35 Times Unlike singleuse mechanical lock nuts, these nylon insert lock nuts can be removed and reused 35 times while keeping good locking performance, so maintenance and repairs are more convenient and cost less over time.Sealed Labeled Storage Box All 300 nuts come in a sealed plastic case with quantity labels printed inside, so nothing gets lost or mixed up. The seal keeps out moisture and dust. Use torque or socket wrenches and never overtorque for best results.
