30mm Universal Vehicle Cover Lock in CNC Aluminium Alloy with 55mm Screw

This 30mm cover lock is designed as a functional fastener for the engine bays of modified cars, racing vehicles, or general automotive applications. It provides a secure mounting point for components like engine covers or oil caps, utilising a corrosion-resistant aluminium alloy construction. The universal design aims for compatibility across most vehicle models, while the availability in multiple colours allows for personalisation to match different engine bay themes. The product includes a 55mm iron screw and a nut for straightforward installation.
Features and Construction

The cover lock is built from specified materials with a focus on a precise fit and a selection of finishes. Its construction is detailed for practical application in automotive environments.
Material and Build
The lock's head is manufactured from aluminium alloy using CNC processing. The source text notes this material offers low density, high strength, good electrical and thermal conductivity, and corrosion resistance. This makes it a lightweight yet sturdy option for engine bay use. The accompanying mounting screw is made from iron, providing the necessary strength for a secure fastener. The assembly is supplied as one screw and one nut.
Size and Practical Fit
The key dimensions are a head diameter of 30mm and a screw length of 55mm (equivalent to 2.17 inches). The 30mm head size provides a substantial contact area, while the 55mm screw length determines the maximum material thickness it can accommodate. The product is described as universal, designed to fit most vehicle models, which indicates its use is not restricted to a single make or specific component.
Uses and Placement

This product serves a specific role in vehicle modification and maintenance, primarily within the engine compartment. Its design supports both functional security and aesthetic customisation.
Event or Professional Use
For modified racing cars or show vehicles, this cover lock can be used to securely fasten custom engine bay covers or dress-up components like anodised oil caps. The choice between the five available colours—silver, black, gold, blue, and red—allows for colour-matching or accenting within a themed engine bay build. Its aluminium construction helps minimise added weight.
Everyday Home Use
For general vehicle owners or DIY enthusiasts, this lock can serve as a replacement or upgrade fastener for a standard engine cover or oil cap that uses a similar screw-type fitting. The corrosion resistance of the aluminium alloy is a practical benefit for the humid and variable-temperature environment of an engine bay. The universal fit makes it a potential solution for various cars in a household garage.
Benefits and Buying Value

The value of this product lies in its material specifications, compatibility, and the option for customisation, based on the details provided in the source description.
Reuse and Low Maintenance
The aluminium alloy's noted corrosion resistance suggests the lock head should maintain its appearance and function over time in an engine bay without requiring special protective coatings. The simple screw-and-nut design means the component can be removed and refitted as needed for maintenance work on the part it is securing. No specialist care instructions beyond general cleaning are implied by the material properties.
Why Choose This Product
This cover lock offers a combination of a lightweight aluminium head with a strong iron fastener, presented in a universal 30mm size. The availability in five distinct colours provides an aesthetic choice not always found with standard fasteners. For someone seeking a specific colour-matched lock or a corrosion-resistant alternative to a plain steel fastener, this product presents a defined option based on the provided specifications of size, material, colour, and fit.
