S-97093A113 5.1 mm ID x 9.2 mm OD DIN 128A Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance due to the curved spring design that maintains constant tension under dynamic loads
• Enhanced durability with Rockwell C44 hardness steel construction that withstands repeated compression cycles
• Reliable locking performance through the split lock mechanism that prevents fastener loosening in high-vibration environments
• Corrosion-resistant protection from the black-oxide surface treatment that extends service life in industrial conditions
• Precision dimensional compatibility with M5 screw sizes and DIN 128A specifications for consistent fit and function
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Optimized spring action from the curved split design that provides superior elastic recovery compared to flat washers

Professional Applications & Engineering Value

This M5 metric split lock washer delivers critical vibration-resistant fastening solutions for demanding industrial applications. The black-oxide steel construction combined with Rockwell C44 hardness ensures the curved spring washer maintains its elastic properties through countless compression cycles, preventing fastener loosening in machinery, automotive assemblies, and electrical enclosures subject to constant vibration. Engineered to DIN 128A standards, these washers provide reliable performance in precision equipment where maintaining bolt preload is essential. The split lock design creates continuous spring tension that compensates for material settlement and thermal expansion, making them ideal for assembly lines, motor mounts, and structural frameworks requiring vibration-resistant fastening systems that won't compromise under stress.

Specification Summary & Compliance

This split lock washer features precise dimensional specifications with 5.1mm ID, 9.2mm OD, and 0.9mm thickness, engineered to DIN 128A standards for metric fastener systems. The manufacturing process ensures consistent curved spring washer geometry and Rockwell C44 hardness for reliable performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety standards are met for industrial applications worldwide.
