seat bolts

Post by **sidsmith** » Fri Mar 13, 2009 1:32 pm

I have to put some thick carpet underlay under my carpets for soundproofing, the present bolts will be too short to blot the seats down I will need to get some longer ones, so can anyone tell me what size the bolts are .

As they are non standard bolts it's tricky to say what size you need

Just measure how deep your underlay is to find the length you need then buy some bolts the same width as the current ones but longer

I appreciate what your saying perhaps I didn't explain properly, what I want to know is the thread type / size as I don't want to put any bolt in that would cross thread the bracket that's on the floor.

Can't you get the thread type / size from the current bolts? (not meaning to appear awkward but I'm assuming you have the original bolts)

Yes, what I will do is take one to the local hardware shop and see if he can identify / supply me with some. I'm not really up to thread sizes and types etc. Im only just coming to terms with whitworth and bsf etc.

I think they are 5/16" BSF.

You'll be lucky to find a hardware shop that still stocks BSF.

You should NOT bolt the seats down through thick carpet - cut the carpet and underlay so it fits around the seat frame. The frame needs to be solidly fixed to the floorpan - not wobbling about on top of thick carpet!

I doubt if the carpet is inches thick and its just a case of having a long enough bolt to start the thread then tighten it down. The correct bolts are available , so if you wish to PM me I can help you out.
If you are seriously worried about seat safety guy's,you should add rear location points to stop the seat lifting under heavy braking or a crash. They really are dangerous, and yes I have seen evidence of injury due to this crazy design.

are rear location points available commercially

I dont think so, but it wouldnt be hard to engineer something

The Mini uses a 'sprung clip' to secure the seat rear frame. Could be adapted for Minor use. But with seat belts fitted - it really shouldn't be a problem - although my MOT man used to complain about my 'adjustable' seat every year - so now I fit an old fixed seat - and do up the hinge bolts REALLY tight so it can't swing up!
