Flat WasherThis aftermarket flat washer spreads clamp load across a soft or oversized hole, protects painted surfaces, and provides a bearing surface for nuts and bolt heads on forklift assemblies. Maintenance shops stock common SAE and metric sizes because flat washers are consumed during every rebuild and routine fastener replacement. Independent mechanics rebuilding mast assemblies, hydraulic brackets, and counterweight hardware are typical buyers. Sold as a crossover aftermarket replacement, not OEM. Confirm bore diameter, outer diameter, and thickness against your application before ordering, since washer dimensions vary between SAE, USS, and metric standards even at the same nominal bolt size.Aftermarket replacement part, cross-references original part number AC01643-00823.Need help confirming fit?
