Product Features & Applications

This CAT dump truck hexagonal castle nut (part number 1B4445/1B-4445) is an OEM specification lock nut specially designed for axles, hubs, steering tie rods and other parts of CAT mining dump trucks. Made of high-strength alloy steel with galvanized anti-rust surface, the slotted castle design achieves double anti-loosening effect with cotter pins, effectively preventing nut loosening under heavy-duty conditions and ensuring the connection reliability and driving safety of key vehicle components.

This hexagonal castle nut is forged from high-strength alloy steel and heat-treated for high tensile strength and excellent impact resistance, suitable for the heavy load and high vibration conditions of mining dump trucks. The galvanized surface provides rust and corrosion resistance to extend service life; the top slotted design can be used with cotter pins for mechanical locking, preventing nut loosening due to vibration during vehicle operation. It is a core locking accessory for key parts such as axle shafts, hub bolts and steering ball joints.
Part number 1B4445 is the original standard specification with high thread precision and tight fit. The installation dimensions are completely matched with the original parts for direct replacement, an important accessory to ensure connection reliability and reduce failure risks of mining dump trucks.
