DIN25201 Stainless Steel Wedge Lock Washer
DIN25201 stainless steel wedge lock washer is a precision anti-loosening fastening component designed to maintain bolt preload in high-vibration and dynamic load applications. The DIN25201 stainless steel wedge lock washer uses a double washer wedge locking design to provide reliable mechanical locking performance without depending on friction alone.
Manufactured from corrosion-resistant stainless steel, the DIN25201 stainless steel wedge lock washer combines excellent environmental durability with stable locking capability. It is widely used in automotive systems, railway equipment, industrial machinery, marine applications, renewable energy equipment, and critical bolted assemblies where connection reliability is essential.
Product Overview
The DIN25201 stainless steel wedge lock washer is engineered for fastening applications exposed to vibration, shock, and repeated loading. Unlike traditional locking washers, its wedge locking structure increases clamp force when the joint experiences movement.
The washer pair consists of two matched components with cam surfaces on one side and radial teeth on the opposite side. During installation, the teeth grip the contact surfaces while the wedge effect prevents bolt rotation caused by external vibration.
Available in stainless steel materials such as 304 and 316, the DIN25201 stainless steel wedge lock washer provides excellent corrosion resistance and is suitable for both indoor and demanding outdoor environments.
