The Project Kics adapter for a 10mm nut is intended for use with wide tread spacers to accept a different nut size during installation. It provides the mechanical interface needed when a 10mm nut must be used with the spacer system, helping adapt existing fasteners to the wide tread spacer hardware without changing the spacer itself.
