I must have misread a bunch of advice and sourced an RT10 Ribe 1/2" bit for the head bolts on my T4, however on closer inspection they appear to be a spline.

Are these triple squares M12s?

Asking before I spend more of my hard earned on tools I will never use again....

Hi all.
I have just purchased a 6R. I would like to pull the front seats out to give the floor and interior a full detail.
What precautions do I need to take removing the seats? Do they have any sort of pre-tensionors or just the seat belt switch?
I have the spline / triple square/...
