DIN25201 Spring Steel Wedge Lock Washer
DIN25201 spring steel wedge lock washer is a high-performance anti-loosening fastening component designed to maintain bolt preload and prevent loosening under vibration, shock, and dynamic loads. The DIN25201 spring steel wedge lock washer features a double washer wedge locking structure that creates a secure mechanical locking effect without relying on friction.
Manufactured from high-strength spring steel, the DIN25201 spring steel wedge lock washer provides excellent elasticity, fatigue resistance, and reliable locking performance. It is widely used in automotive systems, heavy machinery, railway equipment, wind power installations, construction machinery, and industrial assemblies where fastening reliability is critical.
Product Overview
The DIN25201 spring steel wedge lock washer is engineered for applications where standard spring washers or flat washers cannot provide sufficient resistance against bolt loosening. The washer consists of a pair of matched washers with cam surfaces on one side and radial teeth on the opposite side.
During operation, external vibration or dynamic loads may cause a joint to loosen. However, the DIN25201 spring steel wedge lock washer uses the wedge locking principle to increase tension between the bolt head, nut, and assembly surface, maintaining a stable connection.
As a specialized industrial fastener accessory, it is commonly selected by OEM manufacturers, engineering companies, and equipment suppliers requiring dependable anti-loosening solutions.
