Hex NutHex nut offered as an aftermarket replacement; contact us to verify fit before ordering fastener used across forklift powertrain, mast, and chassis assemblies. Replacement nuts matter on lift trucks because mast carriage, counterweight, and wheel hardware sees shock loads every pallet cycle, and a stripped or fatigued nut becomes a safety incident quickly once clamp load is lost. Maintenance shops order standard hardware in bulk to keep technicians from substituting whatever is closest in the bin, which is how the wrong grade ends up in a critical joint. Jam nuts, finished hex, and flange variants all share this footprint.
