Handy Car Wheel Fitting Aid

[Frank S]

Lug bolts are somewhat commonly used on trailers and farm equipment in the US, in addition to what Frank S said above.
Chrysler/DeSoto and some others also used left-handed thread on the left side of the vehicle for a few years. Very frustrating.

The only part that made it frustrating was not all cars used left hand thread on their cars. Semi-truck manufactures adopted the idea of lefthand thread early on with the idea that the lug nuts would not have a tendency to loosen if they were threaded so they would tighten in the direction of the rolling direction of the tire
It must have some merit because I have had a trailer come in where the hubs had been installed on the wrong side the driver complaining that he couldn't keep the lug nuts tight on one of his axles of a trailer he had just bought I noticed that 1 axle had the hubs switched side to side I swapped them and his problem went away
