Seat To Base Bolts

[Cakks]

Hi Folks,
I'm changing my double bench seat with swivel to a single with swivel. Bought the single seat without a base, bought the swivel with safe unit, both are on route but I've no bolts to attach the two together,
Does anyone know what size they are ?
Thanks

Make sure you get the bolts in the correct tensile grade too.

Cheers, thanks for the advice,
need to find out what size first.

My single captains seats use M8 bolts, the front ones have a stud as part of the base so just needs a nut to go onto it, the rears are M8 x approx 20mm long that go into a threaded hole on the seat base.

Brilliant, thank you.

Not sure which swivel base you are getting but I got some replacement M8 button head and M8 countersunk for my RIB base as follows:
M8 ( 8mm ) High Tensile 10.9 Socket Countersunk Screws Black Self Colour Bolts | eBay and
M8 ( 8mm ) High Tensile 10.9 Socket Button Head Screws Black Self Colour Bolts | eBay

These are 'High Tensile 10.9' as originals.

Hi. What bolts did you use in the end? I'm in the same boat now. Thanks.

Hi Plumby,
I was lucky, the seat came with the 4 bolts, I didn't know that when I bought it so was a welcome surprise.
Good luck,
