1/2-Inch Wheel Stud
A 1/2-inch Ford wheel stud has a UNF thread and does not include lug or mag wheel nuts.
Wheel studs sold by Couplemate are high tensile.
However, high-tensile steel studs still require daily inspection when travelling. Wear and tear from rough roads can have disastrous consequences, as shown in the image below.
How do wheel studs become loose?
Firstly, we rarely see loose wheel studs caused by faulty manufacture. It is important to note that all wheel nuts are tightened correctly.
One loose wheel nut often causes all the wheel nuts to loosen.
Long-distance travel and corrugated road travel mandate checking the tightness of wheel nuts every morning before breaking camp.
Loose Axle U-bolts cause highway havoc.
We are also able to supply custom-made 10″ drums and unbraked hubs.

Is wheel stud sheer common?
Yes, worn wheel studs are more common on caravans than trailers.
The left is a simple example of sheer, where the studs can be replaced.
Most reputable caravan and trailer repairers carry wheel studs for standard hubs and drums like Ford, Land Cruiser, and Holden.
If the stud is loose in the hub or drum, the entire part must be replaced.
Hole size is critical for the stud knurl to lock itself into position; therefore, any sign of a loose fit can be expensive.
Tightening the wheel nuts on your spare wheels is also a good idea. It is not uncommon to lose a wheel on rough trips.
Finally, stripping wheel nuts is uncommon; we do not see it occur with high-tensile equipment. The stud will shear before a nut will strip its thread.
How can I identify loose wheel nuts?
A very cheap and easy way to identify loose wheel nuts is to use plastic wheel nut indicators.
These indicators slide over the wheel nut and provide a positive indication should the nut move.
