Professional Applications & Engineering Value

This M12 split lock washer delivers critical engineering value by solving vibration-induced fastener failure in industrial applications. Manufactured from 316 stainless steel, it provides exceptional resistance to corrosive environments including chemical processing, marine, and food industry applications where moisture and aggressive media are present. The DIN 127B standard split lock design creates continuous spring tension that compensates for thermal expansion, material relaxation, and vibration - common causes of joint failure. The metric dimensions ensure precise compatibility with M12 fasteners in machinery, equipment assembly, and structural applications where maintaining preload is essential for safety and performance. This vibration resistant washer eliminates the need for frequent retightening, reducing maintenance costs and downtime in demanding operational conditions.

Specification Summary & Compliance

This split lock washer conforms to DIN 127B dimensional standards with precise metric measurements: 12.7mm inner diameter, 21.1mm outer diameter, and 2.3-2.7mm thickness range. Manufactured from 316 stainless steel for optimal corrosion resistance, the washer is specifically engineered for M12 screw applications. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across multiple sectors.
