I was a Contract Driver...I didn't own the wheel nuts...This is the problem in the industry...similarly to the trailer plugs ie Narva...how many combinations were/are there...liddle round ones in WA, flats in other states and Big round in another... King Pins for example... 3 inch and 2 n halve.... Bloke asked me if I had collars when i turned up for the first time,... I said sorry mate I've only Got "T shirts" HaHa just so many different terminologies even Government can't agree... end result the "Contract driver must wear the cost of Maladministration"
