A 5/8-inch split lock washer made from hardened spring steel with a zinc-plated finish.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It is placed under a nut or bolt head to resist vibration loosening, thanks to its trapezoidal cross-section that bites into the mating surface. Commonly used on heavy-duty truck and trailer assemblies, particularly axle U-bolts and suspension hardware. Replace the washer whenever it flattens, cracks, or loses its spring tension, or when the fastener is removed.
