Mini Headlight Bolts (mainly mini models R55, R56, R57, R58, R5,9 R60, R61) have a habit of corroding inside their housing. The headlight bolts screw into captive nuts, moulded into the plastic housing. When undoing the headlight bolts, if the bolts are seized (corroded), the captive nuts break free. You then can’t undo the bolts, as they just go round and round, without ever coming loose!
I tried to undo the headlight fixing bolts, but the captive nut just kept going round & round..?
Here’s one of the headlight bolts and the different components…
I tried to grab the fixing From behind, but I needed to move the air intake pipe & the water expansion chamber. There wasn’t much of the captive nut to grab hold of, and the bolt was seized tightly in place.
I failed. I just couldn’t undo the bolt!
Don’t undo the headlight adjuster, (unless you’re adjusting the headlights)!
How to Get the Captive Bolt Out.
So, how do I get the bolts undone?
The captive nuts are held in place by a plastic mounting bracket…
Using a bit of heat (from friction). We can remove the rotating captive nut whilst it’s fixed to the bolt! For this we need a drill or a powered driver…
Rotating at speed causes the captive nut to heat up. Gently levering the bolt out speeds things up! But don’t lever off anything that can break.
The Bolt (and the captive nut) has been removed.
