S-91169A317 7.4 mm ID x 14 mm OD DIN 6905 Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through curved spring design that maintains constant tension under dynamic loads
• Exceptional durability with Rockwell C44 hardened steel construction that withstands repeated compression cycles
• Precise M8 compatibility with 7.4mm inner diameter ensuring perfect fit and optimal locking performance
• Reliable industrial performance backed by DIN 6905 certification for consistent quality and dimensional accuracy
• Enhanced safety and compliance with full RoHS 3 and REACH environmental regulations
• Optimal spring action from 2.8mm overall height providing effective locking force in compact spaces
• Reduced maintenance requirements through hardened steel material that resists deformation and wear

Professional Applications & Engineering Value

These M8 split lock washers deliver critical vibration resistance in demanding industrial environments where loosening under dynamic loads poses significant safety risks. The curved spring design creates continuous radial pressure that compensates for thermal expansion, material relaxation, and vibration-induced movement. Manufactured from Rockwell C44 hardened steel, these washers maintain their spring properties through thousands of compression cycles, making them ideal for automotive assemblies, heavy machinery, electrical enclosures, and precision equipment. The DIN 6905 specification ensures dimensional consistency and reliable performance in metric fastener systems, while the 14mm outer diameter provides optimal surface contact for secure locking without damaging mating surfaces.

Specification Summary & Compliance

This split lock washer features precise metric dimensions with 7.4mm inner diameter, 14mm outer diameter, and 1.6mm thickness, manufactured to DIN 6905 standards for dimensional accuracy and performance reliability. The curved spring configuration provides consistent locking force while the Rockwell C44 hardness ensures long-term durability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, this washer meets the highest industry standards for safety and environmental responsibility in industrial applications.
