Spring Washers (Lock Washers / Helical Washers) are designed to prevent loosening of fasteners due to vibration or dynamic loads. Installation involves placing the washer between the fastener head or nut and the substrate; when the fastener is tightened, the washer compresses slightly, creating a spring tension that maintains a secure grip.

Spring Washers are widely used in machinery, automotive, electrical, and structural applications where vibration or movement is expected. Available in materials such as stainless steel, mild steel, and alloy steel, they provide reliable locking action, corrosion resistance, and long-lasting performance in both indoor and outdoor environments.
