• Broad BH and EH Series Coverage — Compatible across the BH 22, BH 23, BH 24, BH 55, and BH 65 gasoline breakers and the EH 22 through EH 100 electric breaker families, as well as select FU frequency converters.
• Correct Load Bearing for Breaker Assemblies — A properly sized flat washer distributes fastener clamping load evenly across mating surfaces; an incorrect or worn washer can allow fasteners to loosen under the high-vibration conditions typical of demolition breakers.
• Verified OEM Part Number — Ordering by Wacker Neuson part number 5000010662 confirms you receive the correct washer geometry and material grade, eliminating the risk of substituting an incompatible hardware item.

A flat washer serves as a load-distribution interface between a fastener — such as a bolt or nut — and the surface it bears against. In high-vibration equipment like demolition breakers, washers play a critical role in preventing fastener heads and nuts from pulling through or damaging softer mating surfaces, and in maintaining consistent clamping force under repeated impact cycles. When a washer deforms, corrodes, or goes missing, fasteners can work loose during operation, leading to misalignment of components, accelerated wear on mating parts, or structural failure of the assembly.
