Bolts for fixing rear of seat to seat frame.

I’m removing the swivel base from the passenger seat.

It it attached with a counter sink bolt.

What size bolt do I need to re-attach the seat runner to the base?

I’m assuming there is a captive nut underneath.

so having done some research, I think these are M8 high tensile 20mm bolts and high tensile M8 nuts
