Professional Applications & Engineering Value

This M24 split lock washer delivers critical vibration-resistant performance for industrial assemblies subjected to dynamic loads and thermal cycling. The blue-dyed steel material combines visual identification benefits with inherent strength, while the Rockwell C38 hardness ensures the split design maintains its spring tension through repeated compression cycles. Engineered to ASME B18.21.2M standards, this metric lock washer provides reliable prevention against fastener loosening in heavy machinery, automotive systems, and structural applications where vibration resistance is paramount. The precise 24.5mm internal diameter creates optimal interference fit with M24 fasteners, distributing load evenly while the split configuration generates continuous opposing force to maintain bolt tension.
