S-93837A190 25.5 mm ID x 35.9 mm OD DIN 7980 Split Lock Washers for Socket Head Screws

Key Features & Benefits at a Glance

• Superior vibration resistance thanks to the split lock design that maintains tension under dynamic loads
• Enhanced corrosion protection with zinc-plated steel construction for longer service life in harsh environments
• Consistent performance ensured by Rockwell C44 hardness, providing reliable spring action and fatigue resistance
• Precise fit for M24 screws with 25.5mm ID and 35.9mm OD dimensions, ensuring secure fastening without slippage
• Industry-standard compliance with DIN 7980 specifications for guaranteed interchangeability and quality
• Environmental responsibility through RoHS 3 and REACH compliance, meeting strict regulatory requirements
• Optimized thickness range (4.8-5.2mm) providing ideal deflection for effective locking while preventing over-compression

Professional Applications & Engineering Value

This M24 split lock washer delivers critical vibration-resistant fastening in demanding industrial applications where joint integrity is paramount. Manufactured from zinc-plated steel, it provides essential corrosion protection for machinery, automotive assemblies, and structural connections exposed to environmental elements. The standard split lock design creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loads – effectively preventing loosening in high-vibration environments. With Rockwell C44 hardness, the washer maintains its spring characteristics through repeated loading cycles, making it ideal for heavy-duty equipment, conveyor systems, and manufacturing fixtures where maintenance downtime must be minimized. The metric dimensions ensure perfect compatibility with M24 fasteners in European machinery and global industrial applications.
