These nuts have the correct 21mm hex head and 60° tapered (cone shaped) seat to fit original Ford alloy wheels perfectly. However, it should be noted that these nuts are a compatible item - not original Ford parts. This does not compromise their fit or safety when in use.
About the quality
Unlike some cheap nuts from China these are made in the EU, in an ISO9000 approved factory and have TUV approval.
Bright zinc plated finish
These nuts have a bright zinc plated finish. This gives them a chrome-like appearance which is super tough and corrosion resistant. This finish will not chip, scratch or rust, like cheap wheel nuts. NOTE: Ensure acidic wheel cleaners are not used!
After-Market alloy wheels
Most after-market alloy wheels (non-original Ford wheels) also use a 60° tapered seat, so in most cases these nuts can also be used with them. It is always best to check with the wheel manufacturer though.
