Professional Applications & Engineering Value
These M3.5 split lock washers address critical vibration-induced loosening in industrial assemblies where maintaining bolt preload is essential. The 18-8 stainless steel material offers exceptional corrosion resistance, making them ideal for harsh environments including marine applications, food processing equipment, and outdoor machinery. The standard split lock washer type creates continuous spring tension that compensates for thermal expansion and vibration, preventing joint failure in metric fastener systems. Engineered to DIN 7980 specifications, these components deliver predictable performance in automotive subassemblies, electrical enclosures, and precision machinery where reliable vibration damping is paramount.
Specification Summary & Compliance
This split lock washer features precise metric dimensions with 3.9mm internal diameter and 6.1mm outer diameter, specifically designed for M3.5 screw sizes. Manufactured to DIN 7980 standards for dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications. Made from corrosion-resistant 18-8 stainless steel with thickness ranging between 0.9-1.1mm for optimal locking performance.
