Locking wheel nuts for steelies

Hi
Fancy putting locking wheel nuts although we only have the original steelies on so this would entail some new shiny wheel nuts to match.
Seen plenty of sets on ebay but they all mention alloys. Would there be a problem with using them on steelies?

hi there try these i have off set steel rims with 30/9.5/R15 tyres and are using these they seem to do the trick but i would'nt put them on with air gun just nip up with hand bar, i've had other locking nuts snap with air gun and been advised by many people to just use bar. hope it helps

Usually Alloy wheels and Steel wheels vary in thickness.
This is the reason they specify Alloy wheels.

Steel wheels are usually thinner and alloys usually have more of a recess ... Hence the Alloy versions are longer.

Alooy .. usually better
