Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M3 split lock washers provide critical vibration resistance where fastener security is paramount. The curved spring washer design creates continuous axial pressure that compensates for thermal expansion, material relaxation, and dynamic loads. Manufactured from zinc yellow-chromate plated steel, these washers maintain their locking force in corrosive environments while the Rockwell C44 hardness ensures the spring characteristics remain stable through repeated loading cycles. Ideal for machinery, automotive assemblies, and electrical enclosures, these DIN 128A compliant washers deliver reliable performance in applications where vibration-induced loosening could lead to equipment failure or safety hazards.

Specification Summary & Compliance

These metric split lock washers feature precise dimensions (3.1mm ID, 6.2mm OD, 0.6mm thickness) manufactured to DIN 128A standards for dimensional accuracy and performance consistency. The zinc yellow-chromate plated steel construction meets industry corrosion resistance requirements while maintaining Rockwell C44 hardness for optimal spring performance. These washers are designed specifically for M3 screw applications and comply with relevant industrial specifications for material quality and manufacturing consistency.
