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 checking each morning when travelling. Wear and tear from rough roads can have disastrous results, as can be seen from 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 results in all the wheel nuts becoming loose.
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 simply be replaced.
Most reputable caravan and trailer repairers carry wheel studs for common hubs and drums like Ford, Landcruiser, and Holden.
In cases where the stud is loose in the hub or drum, the entire part needs replacement.
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 sheer before a nut will strip its thread.
How can I identify loose wheel nuts?
A very cheap and easy solution to identify loose wheel nuts is plastic wheel nut indicators.
These indicators slide over the wheel nut and provide a positive indication should the nut move.
