BMW has filed a patent for a new roundel-shaped screw head that would require a custom brand-specific tool to turn. The design replaces standard fastener patterns such as torx or hex with a shape inspired by BMW’s circular logo.

According to the patent documentation, the screw head features raised and recessed sections that would prevent conventional tools from engaging with it. Servicing components secured with the fastener would require a matching driver designed specifically for this pattern.

While the filing does not confirm that the screw is already in use or will appear on production vehicles, it has sparked concern among independent mechanics and right-to-repair advocates. If implemented, the design could make certain repairs more difficult for owners and third-party workshops that do not have access to BMW-specific tools.

Automakers regularly file patents that never reach production, and BMW has not indicated when or where the fastener might be used. However, similar moves by manufacturers in the past have gradually shifted more servicing and maintenance work back to authorised dealerships.

The patent adds to the growing debate around vehicle ownership repair rights as modern cars become increasingly reliant on proprietary hardware software and tooling. Whether this particular design ever reaches the road remains to be seen.
