I ordered 4, came to fit them and only 2 fitted ok. They all have an internal dimension of 52mm at the top. Two of them have an internal dimension of 51mm at the bottom by the thread and the other two were 50mm at the thread and therefore not square. Didn't land up using them as I didn't want to force and scratch the galvanising on my trailer. For the price, you'd expect better quality control.
