China Coil Spring Washer Manufacturer, Supplier, Factory

When it comes to securing bolted joints against loosening due to vibration, shock, or thermal cycling, specialized components are essential. For engineers and purchasing managers seeking reliable solutions, understanding the distinct types and applications of washers is crucial. A Coil Spring Lock Washer functions by applying a continuous spring force, maintaining tension in the assembly. For applications requiring a different spring characteristic and self-locking capability, the Wave Single Lock Wasasher offers a wave-like design that compensates for material settlement and gaps. The Wave Single Spring Washer is another variant, primarily designed to provide a consistent spring force. Finally, the Wave Single Spring Lock Washer combines the benefits of both spring action and positive locking, making it a versatile choice for demanding environments. Selecting the correct washer type is fundamental to the longevity and safety of any mechanical system.

The Coil Spring Washer itself is an engineering marvel of simplicity and effectiveness. Its helical, open-coil design allows it to function as a compact spring. When compressed between a nut and a surface, the Coil Spring Washer exerts a counter-force, which helps to maintain the clamp load on the bolt. This action is critical in preventing the nut from rotating loose. The materials and manufacturing processes used for a Coil Spring Washer are chosen to ensure it can withstand high-stress cycles without losing its spring properties. Its wide usage across industries from aerospace to consumer electronics is a testament to its fundamental role in reliable fastening.

• Function: Prevents loosening of fasteners by maintaining tension under dynamic loads.
• Design: Helical, open-coil spring made from square or round wire.
• Installation: Placed under the nut or bolt head, compressed during tightening.
• Reusability: Generally limited; performance may degrade after repeated compression cycles.
• Common Sizes: Available in a wide range to match standard bolt diameters (e.g., M3 to M24, #4 to 1").
