- Precise M5 sizing (5.3mm ID, 11mm OD) ensures a perfect fit and reliable performance with standard M5 fasteners.
- Conical spring design maintains constant tension and a powerful locking action under dynamic loads.
- High Rockwell C42 hardness offers exceptional durability and resistance to deformation under pressure.
- Full compliance with DIN 6796 standards guarantees consistent quality, dimensional accuracy, and reliable mechanical properties.
- RoHS 3 and REACH compliance ensures environmental safety and meets stringent international regulatory requirements.
Professional Applications & Engineering Value
This M5 conical spring lock washer is engineered to solve critical vibration-induced loosening in demanding industrial applications. Its zinc-plated steel material and conical shape work in tandem to provide a continuous spring force that counters rotational forces and thermal cycling, common in machinery, automotive assemblies, and electrical enclosures. The DIN 6796 specification ensures precise metric dimensions and a hardened (Rockwell C42) body that resists flattening, maintaining locking force where standard flat washers fail. This makes it an indispensable component for engineers seeking to enhance the reliability and safety of bolted connections subjected to dynamic stresses.
Specification Summary & Compliance
This washer conforms to the dimensional and mechanical specifications of DIN 6796. Key metrics include an Inside Diameter (ID) of 5.3 mm, Outside Diameter (OD) of 11 mm, and a Thickness of 1.2 mm. It is manufactured from zinc-plated steel with a hardness of Rockwell C42. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various markets.
