S-93837A330 6.1 mm ID x 9.9 mm OD DIN 7980 Split Lock Washers for Socket Head Screws

Key Features & Benefits at a Glance

• Superior vibration resistance prevents fastener loosening in high-stress environments
• Enhanced corrosion protection through zinc yellow-chromate plating for extended service life
• Exceptional hardness (Rockwell C44) maintains structural integrity under heavy loads
• Precise M6 compatibility with 6.1mm ID ensures perfect fit for standard metric fasteners
• DIN 7980 compliance guarantees consistent quality and dimensional accuracy
• Optimized 9.9mm OD design provides maximum surface contact for secure locking
• Reliable split lock mechanism creates continuous spring tension against bolt and surface

Professional Applications & Engineering Value

This M6 split lock washer addresses critical vibration-induced loosening in industrial machinery, automotive assemblies, and heavy equipment. The zinc yellow-chromate plated steel construction provides dual protection against corrosion while maintaining Rockwell C44 hardness for sustained performance in high-torque applications. The standard split lock washer design creates constant spring force that compensates for thermal expansion and mechanical stress, making it ideal for vibration-resistant fastening in manufacturing plants, conveyor systems, and electrical enclosures where reliability is paramount.

Specification Summary & Compliance

Manufactured to DIN 7980 standards with precise metric dimensions (6.1mm ID, 9.9mm OD, 1.5-1.7mm thickness). The standard split lock washer type ensures consistent performance across M6 fastener applications. Material composition and zinc yellow-chromate plating comply with industrial corrosion protection requirements, while the manufacturing process maintains strict dimensional tolerances for reliable integration into metric fastening systems.
