S-92471A120 8.4 mm ID x 18 mm OD DIN 6796 Heavy-Vibration-Resistant Spring Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance with conical spring design that maintains constant tension and prevents fastener loosening under dynamic loads
• Excellent corrosion protection through black-oxide coated 18-8 stainless steel construction, ideal for harsh industrial environments
• Precise dimensional compatibility with 8.4mm ID specifically engineered for M8 screw applications
• Reliable hardness performance with Rockwell C35 rating ensuring consistent spring action and long service life
• International standard compliance meeting DIN 6796 specifications for guaranteed quality and interchangeability
• Environmental regulation adherence with RoHS 3 and REACH compliance for global market acceptance
• Optimized load distribution through 18mm OD design that spreads pressure evenly across fastened surfaces

Professional Applications & Engineering Value

This M8 conical spring lock washer delivers critical vibration-damping performance in demanding industrial settings where constant motion and stress would otherwise compromise fastener integrity. The black-oxide 18-8 stainless steel construction provides dual advantages: the stainless steel core offers excellent corrosion resistance, while the black-oxide surface treatment enhances durability and reduces galling during installation. Engineered to DIN 6796 standards, these washers maintain precise conical spring lock washer geometry that generates consistent opposing force, effectively preventing rotational loosening in machinery, automotive assemblies, and heavy equipment. The combination of Rockwell C35 hardness and optimal thickness-to-height ratio ensures the spring mechanism retains its memory through repeated compression cycles, making it ideal for applications requiring reliable, long-term vibration resistance without frequent maintenance interventions.
