Professional Applications & Engineering Value

This M30 split lock washer delivers critical engineering solutions where vibration loosening threatens assembly integrity. The 316 stainless steel material provides exceptional resistance to chloride-induced stress corrosion cracking, making it ideal for marine, chemical processing, and food industry applications. The split lock washer design creates continuous spring tension against both the nut and bearing surface, effectively countering rotational forces that cause fastener failure. With DIN 127B compliance, this metric standard washer ensures precise fitment in European equipment and machinery. The combination of Rockwell C35 hardness and optimized dimensions (31.7mm ID, 48.2mm OD) provides reliable performance in heavy-duty applications where thermal cycling and dynamic loads are common challenges.

Specification Summary & Compliance
