• Exceptional corrosion protection from zinc-flake coating, extending service life in harsh industrial environments
• Reliable wedge-lock mechanism creates consistent spring tension to maintain clamp load in metric M6 fastener applications
• Optimized dimensional precision with 0.26" ID and 0.43" OD ensures perfect fit and uniform pressure distribution
• Enhanced durability with Rockwell C46 hardness rating withstands repeated loading cycles without deformation
• Versatile top and bottom serration design provides effective locking regardless of installation orientation
• Consistent performance across temperature variations and mechanical stress conditions

Professional Applications & Engineering Value

This M6 spring lock washer addresses critical vibration-induced fastener failure in demanding industrial settings. The zinc-flake-coated steel construction provides exceptional corrosion resistance while maintaining the spring lock functionality essential for machinery subjected to constant motion. The dual serration design on both top and bottom surfaces creates multiple biting edges that dig into both the fastener head and base material, effectively resisting rotational forces in automotive assemblies, heavy equipment, and industrial machinery. The wedge lock system generates consistent spring force that compensates for material relaxation and thermal expansion, ensuring maintained preload in critical joints. With Rockwell C46 hardness, these metric washers withstand high cyclic loading without losing their locking properties, making them ideal for applications where safety and reliability are paramount.

Specification Summary & Compliance

Manufactured to precise metric dimensions with 0.26" internal diameter and 0.43" outer diameter, this spring lock washer maintains dimensional accuracy for M6 screw applications. The zinc-flake coating provides superior corrosion protection while meeting environmental compliance standards. With thickness ranging from 0.070" to 0.080", these washers deliver consistent performance across industrial applications. The dual serration design and wedge lock mechanism ensure reliable vibration resistance in accordance with industrial fastening requirements for machinery and equipment where secure locking is essential.
