• Precise metric sizing (14.7mm ID, 21.1mm OD) for accurate fit with M14 fasteners in international assemblies
• Standardized compliance meeting DIN 7980 specifications for consistent quality and interchangeability
• Environmental responsibility with RoHS 3 and REACH compliance for safe use in regulated industries
• Optimized thickness range (2.8-3.2mm) providing balanced spring action and space efficiency in tight assemblies

Professional Applications & Engineering Value

This M14 split lock washer delivers critical vibration resistance in demanding applications where loosening under dynamic loads poses operational risks. The Black-Oxide Steel construction provides essential corrosion protection for machinery exposed to moisture, chemicals, or outdoor elements, while the Rockwell C44 hardness ensures the washer maintains its spring tension through repeated stress cycles. Engineered to DIN 7980 standards, these metric washers offer reliable performance in automotive assemblies, industrial equipment, and construction machinery where secure fastening is paramount. The split lock design creates continuous upward force that counters rotational movement, making it ideal for high-vibration environments such as engine components, conveyor systems, and power transmission equipment.

Specification Summary & Compliance

This split lock washer features precise metric dimensions with 14.7mm inner diameter and 21.1mm outer diameter, specifically designed for M14 screw applications. Manufactured to DIN 7980 specifications with a thickness range of 2.8-3.2mm, it ensures proper fit and function in standard assemblies. The product maintains RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current substance restrictions, meeting international environmental and safety standards for industrial fastener applications.
