Replacement Wheel Nuts
gingerprince - 2/7/25 at 12:31 PM

Hi, I recently lost a wheel nut and bought what i thought would be a suitable replacement, however now it's arrived I'm not so sure.

It's an MK with Sierra running gear, and aftermarket alloy wheels.

The nuts I currently have are on the left, with the new on the right. Correct thread, taper angle etc, but much smaller taper surface area.

Am I correct in thinking that I've c0cked up, these replacements are only for steel as I need to spread the load more for alloys, and I should seek others?

The one on the left looks to me to be a standard sierra wheel nut with the captive taper cone.

It's not the spinny ones, they're both solid. Just the old ones have more surface area in the taper. Something like 24mm Vs 21mm max.

I saw a video recently showing the importance of using the correct nuts.
Suffice to say it's very important - too late to have taken a chance when they loosen/fall off!
I'd be inclined to ask a local wheel shop for advice.
