Overview
This M42 double lock washer is engineered to deliver a secure, vibration-resistant connection for critical bolted assemblies in heavy-duty industrial applications. Manufactured to the rigorous DIN25201 standard from carbon steel, it provides reliable performance where joint integrity is paramount. The washer's self-locking design maintains consistent clamp load, effectively preventing loosening under dynamic loads and reducing the need for frequent maintenance or re-torquing. A Dacromet finish is applied for superior corrosion resistance, ensuring extended service life even in demanding, exposed environments.
