Product Description

DIN25201 Double Layer Self Locking Washer Wedge Lock Washer for Heavy Machinery

The DIN25201 Double Stack Self Locking Wedge Lock Washer is an advanced fastening solution designed to prevent bolt and nut loosening under extreme vibration and dynamic load conditions. Unlike traditional single piece washers that rely solely on friction, this innovative washer consists of two identical washers used as a pair, utilizing a unique wedge locking principle that delivers superior anti-loosening performance.

Key Features

100% Anti-Loosening Performance - Ensures clamp load remains stable even under severe and continuous vibration, outperforming traditional friction-based locking fasteners
Tension-Based Locking Principle - Utilizes wedge effect instead of friction for locking, making the locking function unaffected by lubrication
Easy Installation and Removal - No special installation tools or procedures required; can be easily installed and removed with standard tools
Reusable - Can be disassembled and reused multiple times without compromising the locking performance
Temperature Resistant - Maintains locking effectiveness across a wide temperature range; stainless steel versions operate from -160°C to 500°C
High Durability - Withstands long-term continuous vibration without loosening
