Application in BMW engines

The presented spacer bolt is designed as a fastening element in the engine area, where maintaining the correct distance between mating parts is crucial. Thanks to its stud-type design, it ensures:

• stable guidance of components in the mounting socket,
• maintenance of proper connection geometry,
• resistance to loads resulting from the operation of the power unit.

Such a solution is particularly important during service and repairs, where repeatability of assembly and maintaining factory engine operating parameters are required.

Construction and technical characteristics

The M8X12 spacer bolt with a working length of L81,5 has been developed for operation in the demanding environment of the engine compartment. The M8 thread allows for secure seating in a properly prepared socket, and the spacer part of the stud is responsible for the proper distribution of forces in the connection. These types of elements are used, among others, for:

• determining the position of engine accessories,
• fastening covers and auxiliary components,
• ensuring the appropriate distance between mating components.

Thanks to the maintenance of factory dimensions, assembly proceeds in a predictable manner, without the need to modify other parts.

Original origin and compatibility

The element comes from the BMW parts group, which means maintaining the vehicle manufacturer's quality standards and full compliance with the intended structural application. Original origin translates into:

• proper fit to the intended mounting points,
• consistency with service documentation and parts catalogs,
• possibility of use in repairs in accordance with the manufacturer's technology.

Additionally, the element has assigned interchangeable numbers, which facilitates identification in catalogs and selection during workshop work.

Condition and benefits of using a used OEM part

The part is offered in Used condition, which in practice means that it comes from disassembly and has been verified for further mounting suitability. Choosing a used OEM element allows you to:

• maintain compliance with factory specifications,
• reduce repair costs while maintaining high quality,
• shorten vehicle downtime thanks to the availability of parts from stock.
