S-93497A340 25 mm ID x 56 mm OD DIN 6796 Heavy-Vibration-Resistant Spring Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with a conical spring design that maintains constant tension, preventing loosening in high-stress applications
• Exceptional durability thanks to Rockwell C42 hardened steel construction, ensuring long service life under heavy loads
• Precise fit for M24 screws with 25mm ID and 56mm OD, enabling easy installation and reliable performance in metric assemblies
• Compliance with DIN 6796 standards guarantees consistent quality, dimensional accuracy, and interchangeability in industrial settings
• Environmental responsibility with RoHS 3 and REACH compliance, meeting strict regulations for hazardous substances
• Optimized load distribution from the conical shape, reducing stress concentrations and protecting mating surfaces
• Reliable performance in harsh conditions due to robust steel material and precise 6.0mm thickness, resisting corrosion and wear

Professional Applications & Engineering Value

This M24 spring lock washer is engineered to address common industrial challenges like vibration-induced fastener failure and assembly instability. Made from high-strength steel with a conical shape per DIN 6796, it provides a spring-like action that compensates for thermal expansion, material relaxation, and dynamic loads in machinery, automotive, and construction applications. The Rockwell C42 hardness ensures it withstands repeated cycles without deforming, while the precise metric dimensions (25mm ID, 56mm OD) facilitate seamless integration with M24 screws, reducing maintenance downtime and enhancing safety in heavy-duty lock washer uses. Its design is ideal for preventing back-off in bolted joints, offering engineers a reliable solution for long-term assembly integrity.

Specification Summary & Compliance

This washer adheres to DIN 6796 for dimensional accuracy and performance, with an inner diameter of 25mm, outer diameter of 56mm, thickness of 6.0mm, and overall height of 7.75mm. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from restricted substances and suitable for global industrial standards. The conical spring lock washer shape and Rockwell C42 hardness are verified to provide consistent locking force and durability in mechanical fastening systems.
