Hex NutThis aftermarket hex nut is a general-purpose fastener used throughout forklift assemblies: engine accessories, hydraulic line brackets, cab hardware, counterweight bolts, and mast component mounts. Maintenance shops stock common sizes by the box because hex nuts get lost, stripped, or corroded during routine service and need ready replacement. Independent mechanics and DIY fleet owners are typical buyers. Sold as a crossover aftermarket replacement, not OEM branded. Verify thread pitch, grade, and finish (zinc, black oxide, plain) against your application before ordering, especially for load-bearing joints where grade matters for torque spec.Aftermarket replacement part, cross-references original part number AC01593-01411.Need help confirming fit?
