Countersunk M8x1.25 Bolt for Brake Discs with 10 mm Hole

This countersunk bolt with M8 thread for brake discs is intended for applications with a 10 mm hole diameter. The bolt has a length of 20 mm, a head diameter of 15.5 mm and a collar diameter of 10 mm. The thread specification is M8x1.25.

This part is not application-specific and is therefore not assigned to a particular motorcycle, scooter, quad or ATV model. Before ordering, you should compare all relevant dimensions with the existing bolt, brake disc and mounting point. Thread diameter, thread pitch, bolt length, head diameter and collar diameter are particularly important when determining compatibility.

Countersunk Brake Disc Bolt with M8x1.25 Thread

When selecting a brake disc mounting bolt, the thread size alone is not sufficient. The shape and diameter of the bolt head, the collar underneath the head and the overall length must also match the brake disc and mounting point. This bolt uses an M8x1.25 thread and is intended for brake discs or mounting points with a corresponding 10 mm hole diameter.

M8x1.25 thread: metric thread with a 1.25 mm thread pitch.
20 mm bolt length: should be compared with the existing brake disc mounting bolt.
15.5 mm head diameter: countersunk head design for corresponding brake disc mounting surfaces.
10 mm collar diameter: intended for corresponding 10 mm brake disc holes.
Universal application: no fixed vehicle-specific fitment is assigned.
Dimension comparison required: thread, length, head shape and collar must match the intended application.

Compare All Important Dimensions Before Purchase

Brake disc bolts can differ considerably even when they use the same nominal thread diameter. Two M8 bolts may have different thread pitches, head diameters, lengths or collar designs. For this reason, the correct bolt should not be selected solely on the basis of the M8 designation.

Pay particular attention to the 1.25 mm thread pitch. An M8 thread with a different pitch is not automatically compatible with an M8x1.25 mounting point. The 20 mm bolt length should also correspond to the available thread depth and the design of the existing brake disc mounting system.

10 mm Collar for Corresponding Brake Disc Holes

The section directly below the bolt head has a 10 mm collar diameter. This dimension is particularly relevant when the bolt passes through a 10 mm brake disc hole or is centred by a corresponding mounting surface.

The 15.5 mm head diameter must also be checked against the existing brake disc. The head needs to fit correctly into the intended countersunk or contact area without interfering with surrounding components.

Universal Part Without Vehicle-Specific Fitment

This M8x1.25 brake disc bolt is not assigned to a specific vehicle model or production year. Compatibility is determined by the technical dimensions and the design of the individual brake disc mounting system.

If the existing bolt has different dimensions, modification of the particular application may be required for correct installation. Before installation, verify that the thread, bolt length, head geometry and collar diameter correspond to the brake disc and mounting point.

Why Accurate Measurements Matter for Brake Disc Bolts

Brake disc mounting components are used in a safety-relevant area of the vehicle. Bolts should therefore not be selected solely because they look similar to the original part. A bolt that is too long may interfere with adjacent components, while a bolt that is too short may not provide the required thread engagement. A different head diameter or collar geometry can also prevent the bolt from seating correctly against the brake disc.

For a reliable comparison, check several dimensions together: M8x1.25 thread, 20 mm length, 15.5 mm head diameter and 10 mm collar diameter. Matching these specifications with the existing component provides a more accurate basis for assessing compatibility.

Suitable for Replacement and Custom Applications

The bolt can be used for replacement, repair and custom applications where all technical dimensions and mounting requirements correspond. Because it is a universal component, it may also be suitable for individually configured motorcycles, scooters, quads or ATVs when the brake disc and mounting point meet the specified dimensions.
