Purpose and mounting parameters

The presented locking bolt set is adapted to hubs and rims in BMW cars where the manufacturer has specified wheel mounting on an M14x1.25 thread and a specific working length of the bolt. This selection of parameters ensures:

• proper seating of the wheel on the hub,
• appropriate depth of the bolt screwed into the hub,
• stable load transfer while driving.

As a result, this set can be used as a replacement for standard wheel mounting bolts while adding an anti-theft protection function.

Design and security function

The locking bolt set for BMW uses a socket profile that requires a dedicated key, which significantly hinders unauthorized removal of the rims. This solution is particularly useful for alloy wheels, which are a frequent target for theft. Using locking bolts:

• increases the level of wheel protection when parked,
• limits the risk of quick rim removal using standard sockets,
• allows for maintaining full functionality of the wheel mounting system.

The carefully selected shape of the head and thread allows for trouble-free cooperation with factory hubs and rims, while maintaining the required clamping parameters.

Product condition and service application

The offered locking bolt set is in used condition, which makes it an attractive proposition for users looking for an economical solution while maintaining functionality. This set will work well both as a replacement for worn or damaged locking bolts and when retrofitting a car that was not previously equipped with this type of protection.

In workshop practice, the set can be used for:

• replacing steel rims with alloy ones,
• wheel and tire system service,
• upgrading vehicle protection against rim theft.

Integration with the ignition system – product category

The product is classified in the Ignition wires and ignition coil connectors category, which makes it easier to search for within the group of elements related to the engine compartment service area. Thanks to this, the user, while browsing components in this section, can plan service work in one place that includes both elements related to ignition and additional accessories mounted within the vehicle.

If you are planning a comprehensive repair or upgrade of the engine area in your BMW and need other elements from the same group, such as high-voltage wires, coil connectors, or ignition harnesses, check the available parts in the Ignition wires and ignition coil connectors Unbranded category.

Mounting and operational tips

When selecting locking bolts for a BMW, it is crucial to pay attention to the compatibility of the thread, working length, and socket shape with the rims and hubs used. It is recommended that installation be performed using an appropriate torque wrench, in accordance with the vehicle manufacturer's recommendations regarding tightening torque. Regular inspection of the bolt condition during seasonal tire changes allows for maintaining the stability of the wheel mounting and avoiding problems with removal in emergency situations.
