Caravan and Trailer Wheel Studs from 7/16 inch to 5/8 inch short and long knurl

Caravan and trailer wheel studs from 7/16 inch: Holden UNF to 7/8 inch. This section does not include lug nuts or mag wheel nuts.

The most common request we get is for a metric stud conversion, especially 14mm studs to replace 9/16" Landcruiser studs.

Did you know that Alko wheel studs are high-tensile steel?

Yes, however, high-tensile steel studs still require checking each morning when travelling. Wear and tear from rough roads has disastrous results as can be seen from the image below.
