NFE 25-511 Conical Lock Washers

Product Description

This product complies with the NF E 25-511 standard and is manufactured from specialized spring steel. Its unique conical structure provides a durable compensatory preload, while the staggered radial serrations on the surface are designed to embed deeply into the mating surfaces. This combination delivers exceptional anti-loosening and locking performance under conditions of intense vibration and high alternating loads.
 

Industry Applications 

This solution is widely utilized in electrical engineering (busway connections), rail transit bogies, large generator sets, and automotive powertrains. It is specifically optimized for threaded connection scenarios with stringent requirements for conductive stability and seismic resistance, serving as a professional standard solution for managing industrial-grade vibrations and preventing bolt fatigue loosening.
