Morris Minor Owners Club

Hi,

I'm fitting a new pair of headlights to my car which has fibreglass wings. The previous pair were fixed using self tappers into the wing but I was wondering what the standard procedure was. It seems that with steel wings, the lights are fixed using 2BA screws into captive nuts. I wondered if it would be a good idea to drill holes and then mount with bolts, washers and nuts.

Thanks
James

I would use 2BA (or similar) screws with a washer and nut on the back. And some copper grease on the threads so you can undo them at some time in the future if required!

Words to live by MM, words to live by!

I used stainless m5 screws with nuts and washers. I’m not claiming this is necessary, I just picked up a big cheap pack of metric fastners.

Thanks for the suggestions. I've mounted them using 2BA screws and bolts with penny washers. I bought some copper grease this morning and then forgot to put it on the screws!

Thanks,
James

I keep an aerosol of bilt hamber underbody wax in the workshop giving thing like bolts a squirt of that protects them well enough.

I vaguely remember reading something about 'dry' vs 'oiled' torque settings. Does copper grease affect the torque required to keep the bolt secure?

Cylinder head nuts should be torqued up dry unless specified by the manufacturer.
Oiled threads allow the nut to reach its required torque much later so increasing the loading and stretch on the stud.
