Overview
This double-thick lock washer is engineered to meet the rigorous DIN 25201 standard, providing a high-performance, vibration-resistant locking solution for M4 fasteners. It is designed for critical assemblies where joint integrity is paramount. Manufactured from durable 304 stainless steel with a plain finish, this washer offers excellent corrosion resistance for use in harsh or washdown environments. The dual-layer, self-locking design generates a powerful and consistent spring force to prevent fastener loosening caused by dynamic loads, thermal cycling, and shock. Supplied in a bulk pack of 1000 pieces, it is an efficient and reliable component for high-volume production, maintenance, and repair operations.
Key Features
Manufactured to DIN 25201 specification for assured dimensional consistency and performance. Double-thick design provides enhanced spring action and superior locking force compared to standard single-thickness washers. Constructed from corrosion-resistant 304 stainless steel for longevity in demanding environments. Plain, non-plated finish is suitable for applications requiring material purity and high-temperature resistance. Self-locking action maintains clamp load and prevents spontaneous loosening under vibration. Bulk packaging of 1000 units supports streamlined inventory management and production efficiency.
