Hi all,

A few small bits and pieces are getting in the way of progress on my mini project.

Does anyone know what size the bolts/screws are for the air vent fittings on the flitch panels? Once I've fitted these I can pretty much finish my dash.

Also, what size nuts do I need to fit the horn on the front panel? There are 2 bolts welded onto the front panel, I need nuts for them.

I also need bolts for the seat brackets.

I dont want to go out and buy another mixed pack as I now have loads of bolts I don't need, and just need a few bits and bobs to finish the car. I'm sick of going out and buying the wrong sizes as well.

Thanks again all!

For the seat brackets, assuming you mean the ones into the cross member as far as i'm aware they are 8.8mm

their isnt a bolt at 8.8mm..... unless its hand made lol.... what you are looking at is the 8.8 that is stamped on the bolt head... this indicates the GRADE of bolt and by the way id not be happy with 8.8 grade in my seat fixings... 8.8 is a metric grade so it sounds like someone has changed your bolts to a lower grade of fixing in metric size. ( not good at all) I dont know the size off hand.... but its not 8.8mm and virtually all the nuts and bolts on Minis will be IMPERIAL sizes anyways... ..... if you want AND ONLY IN NONE CRITICAL AREAS LIKE THE AIR VENT FIXING... you could, if desperate, substitiute metric sizes ie M4 for 3/16, M6 fpr 1/4 and mate for 5/16........ but you really should get IMPERIAL SIZES and, in critical areas like seat fixings, get the right GRADE of bolt

Metric fixings generally denote grade by the stamping as follows Class 8.8 Medium Carbon Steel, Quenched and tempered, Class 10.9 Alloy Steel, Quenched and Tempered, Class 12.9 Alloy Steel, Quenched and Tempered but with higher proof load, higher yield strength and highr tensile strength


Imperial bolts are denoted by marking the head with a series of dash marks No dash marks indicate Grade 2 Low or medium carbon steel, 3 dash marks Grade 5 Medium Carbon Steel, Quenched and Tempered, 6 dash marks Grade 8
Medium Carbon Alloy Steel, Quenched and Tempered but with higher proof load, higher yield strength and highr tensile strength

Dont just replace bolts willy nilly... ALWAYS check the grade required


Hope this helps
Rob
