S-97093A139 3.1 mm ID x 6.2 mm OD DIN 128A Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance due to the curved split design that maintains constant spring tension under dynamic loads
• Reliable corrosion protection with 18-8 stainless steel construction for longevity in harsh industrial environments
• Precision dimensional compliance with DIN 128A standard ensuring consistent performance in M3 fastener applications
• Optimal load distribution through curved geometry that minimizes surface damage while providing secure locking
• Environmental regulation compliance meeting RoHS 3 and REACH standards for global manufacturing applications
• Easy installation and removal with split design that accommodates thermal expansion and contraction cycles
• Cost-effective maintenance solution by preventing fastener loosening and reducing assembly downtime

Professional Applications & Engineering Value

This M3 curved split lock washer delivers critical vibration damping in demanding applications where 18-8 stainless steel provides essential corrosion resistance. The DIN 128A compliant curved design generates continuous spring force that counters rotational loosening in machinery, electrical enclosures, and automotive assemblies. Unlike flat washers, the curved split lock washer type maintains tension through thermal cycling and mechanical stress, preventing costly fastener failure in industrial washers applications. The precise 3.1mm ID and 6.2mm OD dimensions ensure perfect fitment with M3 fasteners while the curved profile distributes clamping force evenly, protecting sensitive surfaces from galling and deformation in repeated maintenance cycles.

Specification Summary & Compliance

Manufactured to DIN 128A specifications with precise metric dimensions (3.1mm ID × 6.2mm OD × 0.6mm thickness). The 18-8 stainless steel construction provides consistent mechanical properties without hardness rating requirements. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety for global industrial applications. Designed specifically for M3 screw size applications with curved split configuration that maintains locking performance across standard operating temperature ranges.
