Key Features & Benefits at a Glance
- Superior vibration resistance prevents fastener loosening in high-stress environments, ensuring long-term joint integrity.
- Exceptional corrosion protection from the zinc yellow-chromate plating, extending service life in harsh industrial conditions.
- High hardness (Rockwell C44) provides reliable spring action and maintains locking force under heavy loads.
- Precise M12 metric sizing with 12.2mm ID and 18mm OD ensures perfect fit and consistent performance in standard assemblies.
- DIN 7980 compliance guarantees dimensional accuracy and interchangeability for European and international projects.
- Durable steel construction offers excellent strength-to-weight ratio, resisting deformation under torque and vibration.
- Easy installation and removal with standard split lock design, reducing maintenance time and labor costs.
Professional Applications & Engineering Value
This M12 split lock washer is engineered to solve critical vibration-induced loosening in industrial machinery, automotive assemblies, and structural frameworks. The zinc yellow-chromate plated steel material combines high tensile strength with superior corrosion resistance, making it ideal for outdoor or humid environments where rust compromises fastener reliability. Its split lock washer standard design applies continuous radial pressure, maintaining clamp load despite dynamic stresses. By meeting DIN 7980 specifications, it ensures precise metric threading compatibility, reducing the risk of assembly errors and component failure in vibration-resistant applications.
Specification Summary & Compliance
This washer conforms to DIN 7980 standards with precise dimensions: 12.2mm ID, 18mm OD, and 2.3-2.7mm thickness for M12 screw sizes. Manufacturing follows strict quality controls for Rockwell C44 hardness and dimensional tolerances. The zinc yellow-chromate plating provides RoHS and REACH compliance, ensuring environmental safety and corrosion protection for industrial use.
