BMW part number 34211164125 is an exceptionally universal hardware component: the Hex Head Brake Caliper Carrier Mounting Bolt (M10 x 26mm). Because it is a basic structural bolt used to secure the rear brake caliper brackets to the wheel hub/trailing arms, its application span is massive. It fits nearly every single mainstream BMW chassis generation spanning from 1976 through 2016. These were purchased for use with Rear Caliper installations.
When your BMW was originally built at the factory, the assembly line robots or technicians used bare, high-tensile Kamax bolts. They achieved their clamping force and vibration resistance purely through extreme, dry torque stretching against the metal threads of the wheel hub or trailing arm. No threadlock was applied at the factory for the vast majority of classic chassis (E30, E36, E46, E34, E39, etc.). When you order the exact same part number (34211164125) today as a brand-new replacement from a BMW dealership parts counter, the new bolt will almost always come with a factory-applied patch of dry microencapsulated thread-locking compound (usually blue or yellowish-white) pre-applied to the threads.
