Fits Fiat Ducato Boxer Campervan M16 Thread 2007-onwards M16x1.5x30 194/5 Heyner Germany Locking Wheel Nuts Set 4 Car Security Locks Anti-theft

Bolts look good and fit easily to Fiat Ducato 16inch wheels. Key depth guite shallow with one slipping when installed, concerned will have problems when need to remove.

Fit like normal wheel nuts but make sure you get the right size and apply the right torque. Only has one key so also make sure you keep the reference number safely. They say everyone is unique.

One of the fitting slipped when fastening .

The wheel nut locking key fitted loosely and came off the wheel bolt easily. This made it impossible to set the torque to 160 using my torque wrench. I had to take the motorhome to my local garage to get the torque set properly. If I needed to change a wheel I think it pretty doubtful that the nut could be removed by the on board tool kit. Pretty poor engineering IMO.
