Professional Applications & Engineering Value
This M24 split lock washer delivers critical vibration-dampening performance in demanding industrial settings where mechanical shock and dynamic loads threaten fastener integrity. The zinc-plated steel construction provides dual protection against corrosion while maintaining the Rockwell C44 hardness necessary for repeated compression cycles. Engineered to DIN 127B specifications, the split design creates continuous spring tension that compensates for thermal expansion, material creep, and vibration-induced loosening in heavy machinery, structural steel connections, and automotive assemblies. The precise 25.5mm internal diameter ensures secure seating on M24 fasteners while the 40mm outer diameter distributes clamping force effectively, making it ideal for applications requiring reliable vibration-resistant locking solutions in manufacturing, construction, and equipment maintenance.
Specification Summary & Compliance
This standard split lock washer features metric dimensions with 25.5mm ID × 40mm OD and 4.8-5.2mm thickness, manufactured to DIN 127B specifications for dimensional precision and performance reliability. The product maintains Rockwell C44 hardness throughout its zinc-plated steel construction and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for regulated industrial applications requiring certified heavy-duty lock washers.
