Key Features & Benefits at a Glance
- Superior vibration resistance due to the curved split design that maintains constant tension and prevents loosening under dynamic loads.
- Enhanced corrosion protection with zinc-plated steel construction, ensuring durability in harsh industrial environments.
- Consistent performance and reliability from the high Rockwell C44 hardness, which resists deformation under pressure.
- Precise fit for M5 screws with a 5.1mm inner diameter, providing secure fastening and easy installation.
- Compliance with DIN 128A standards guarantees dimensional accuracy and interchangeability in metric applications.
- Environmental and safety adherence with RoHS 3 and REACH compliance, supporting sustainable and regulated manufacturing processes.
- Optimized load distribution through the 9.2mm outer diameter, reducing stress on connected components.
Professional Applications & Engineering Value
This M5 split lock washer is engineered to address common industrial challenges such as fastener loosening due to vibration and thermal cycling. Made from zinc-plated steel, it offers excellent corrosion resistance, making it ideal for automotive, machinery, and electrical assemblies where moisture and chemicals are present. The curved spring washer design applies continuous spring force, compensating for material relaxation and maintaining clamp load in high-stress environments. By meeting DIN 128A specifications, it ensures precise thread engagement and reliable performance in metric fastening systems, reducing maintenance needs and enhancing operational safety in demanding applications like heavy equipment and precision instruments.
Specification Summary & Compliance
This washer features precise dimensions: 5.1mm ID, 9.2mm OD, 0.9mm thickness, and 1.5mm overall height, designed for M5 screw sizes with a curved split lock type. It conforms to DIN 128A standards for dimensional and performance consistency, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
