S-93837A320 5.1 mm ID x 8.8 mm OD DIN 7980 Split Lock Washers for Socket Head Screws

Key Features & Benefits at a Glance

• Superior vibration resistance with the split lock design that maintains tension under dynamic loads
• Exceptional corrosion protection through zinc yellow-chromate plating for extended service life in harsh environments
• Consistent spring action ensured by Rockwell C44 hardness for reliable locking performance
• Precise dimensional fit with 5.1mm ID and 8.8mm OD for perfect compatibility with M5 fasteners
• Guaranteed interchangeability through compliance with DIN 7980 manufacturing standards
• Optimized load distribution with 1.5-1.7mm thickness for balanced pressure across joint surfaces
• Reduced maintenance requirements through durable steel construction and protective coating

Professional Applications & Engineering Value

These M5 metric split lock washers deliver critical vibration resistance in demanding industrial applications where loosening under dynamic loads poses significant safety and performance risks. The zinc yellow-chromate plated steel construction provides dual protection against corrosion and wear, making them ideal for automotive assemblies, machinery maintenance, and outdoor equipment where environmental exposure is a concern. The DIN 7980 standard ensures precise dimensional tolerances and consistent quality across production batches, while the split lock design creates continuous spring tension that compensates for material relaxation and thermal cycling. This engineering solution prevents costly downtime and maintenance by maintaining secure fastener locking in high-vibration environments from manufacturing equipment to transportation systems.

Specification Summary & Compliance

Manufactured to DIN 7980 specifications with precise dimensional tolerances including 5.1mm inner diameter, 8.8mm outer diameter, and 1.5-1.7mm thickness range. The split lock washers feature Rockwell C44 hardness for consistent spring performance and are constructed from zinc yellow-chromate plated steel for corrosion resistance. These components meet international metric standards for M5 screw applications and comply with RoHS and REACH environmental directives for industrial use.
