Original steering stem nut for adjusting the bearing play of the steering head bearings. Suitable for all classic BMW Boxer two-valve engines.
After more than 30 years, the original steering head locknuts are usually badly weathered/rusted and badly damaged by countless (mostly improper) handling. When installing a new top-yoke, you should definitely replace this nut in order to be able to precisely adjust the steering head play again.
