The Door lock (wide body) + ignition lock cylinder + fuel tank cap is the core security set of The part kit. It includes a robust door lock mechanism designed specifically for the wide‑body cab, ensuring a tight seal and smooth operation.
The ignition lock cylinder is precision‑matched to the door lock, allowing a single key to operate both the doors and the ignition, enhancing convenience and reducing the number of keys required. The fuel tank cap is also keyed alike, providing uniform security across the vehicle.
Each component in this Locks and Keys set is manufactured from corrosion‑resistant materials, with hardened steel internal components to resist drilling and picking. The lock cylinders feature multiple tumblers for enhanced security.
Installation of this Locks and Keys set is straightforward, with all parts pre‑assembled and ready to fit into the existing mounting points. The fuel tank cap is supplied with a tethered design to prevent loss during refuelling.
This comprehensive Locks and Keys solution is ideal for fleet operators who require a single key for all cab entry points and ignition, simplifying driver logistics and reducing the risk of lost keys.
The Hexagon socket pan head bolt is a high‑strength fastener used to secure the door lock assembly and other components in The part kit. Its pan head provides a large bearing surface, and the socket drive allows for secure tightening with a hex key.
These bolts are made from grade 8.8 steel with a zinc‑plated finish, offering excellent corrosion resistance and tensile strength. They are supplied in the correct quantity (16 pieces) to cover all mounting points for the lock assemblies.
The pan head design distributes the clamping load evenly, preventing damage to the lock housing and ensuring a secure fit. The hex socket drive reduces the risk of stripping compared to cross‑head screws, making this Locks and Keys installation more durable.
Using genuine hexagon socket pan head bolts ensures that The part components remain firmly attached, even under the vibration and shock of daily driving. Replacement bolts are available individually if needed.
The Hexalobular countersunk head screw is a specialised fastener used for attaching trim panels and delicate components within The part system. Its countersunk head sits flush with the surface, providing a clean, professional appearance.
The hexalobular (Torx) drive offers superior torque transmission and reduces the likelihood of cam‑out during installation, making it ideal for applications where high clamping force is required without damaging the surrounding material.
These screws are made from stainless steel, providing excellent resistance to rust and corrosion. Four screws are included in The part kit, precisely the number needed for securing the lock trim plates and ignition switch housing.
The countersunk design allows the screw head to be flush with the surface, reducing the risk of snagging clothing or damaging the interior trim. This attention to detail makes The part installation look factory‑finished.
The Plastic tie 2.4×92 is a versatile cable tie used for routing and securing wiring harnesses associated with the lock and ignition systems. Its 2.4 mm width and 92 mm length make it suitable for bundling moderate‑sized cable bundles.
Made from high‑grade nylon, this tie is resistant to UV light, oil, and temperature extremes, ensuring it remains flexible and strong over the vehicle’s lifetime. Four ties are included in The part kit, sufficient for securing the lock actuator wiring and ignition harness.
The self‑locking mechanism provides a secure grip that prevents the tie from loosening, even under vibration. Its smooth edges protect the wire insulation from chafing, contributing to the overall reliability of The part electrical system.
Proper cable management with these plastic ties helps maintain a tidy installation, making future diagnostics and repairs easier. This is an important detail for maintaining The part system’s integrity.
This assembly combines a cross recessed pan head tapping screw with a flat washer, providing a fast and secure method for attaching the lock components to the door sheet metal. The tapping screw cuts its own thread, eliminating the need for pre‑tapping.
The pan head design offers a broad clamping surface, while the flat washer distributes the load evenly, preventing damage to the plastic lock housings. These fasteners are made from corrosion‑resistant steel with a zinc‑plated finish.
Four assemblies are included in The part kit, matching the number of mounting points for the door lock actuator and handle brackets. The cross recess drive allows for easy installation with a standard screwdriver.
Using these tapping screws ensures that The part installation is quick and efficient, reducing assembly time and ensuring a tight, rattle‑free fit.
The Spring nut is a self‑retaining fastener that provides a threaded anchor point in thin sheet metal. It is used to secure the lock and ignition components where traditional nuts cannot be accessed from the back.
Made from spring steel with a zinc‑plated finish, this nut is designed to clip into a square hole and provide a reliable thread for the mounting screws. Two spring nuts are included in The part kit, sufficient for the specified mounting points.
The spring tension holds the nut securely in place during assembly, preventing it from falling out or rotating, which simplifies installation. This feature is particularly useful when working in confined spaces.
Using genuine spring nuts from The part kit ensures that the fasteners remain tightly secured, contributing to the overall durability and security of the lock system.
