Clutch spring bolt size??

[Mitch_350z]

Hi all, like a total idiot I've over tightened a clutch spring bolt. Just need to know the thread size of the bolts as I've seen a few different sizes/lengths when looking for some new ones?? I've seen m5 and m6 at different lengths so not 100% sure.
Thanks in advance.

@mitch_350z my 98 DTR is M6 x 20mm

@ricky0115 would that be the same as a 2002 model??

[ricky0115]

@mitch_350z I know it’s the same as 04 DTRE

@ricky0115 alright mate thanks, do you know what size head the bolts are as I haven't got them to hand and can't remember of the top of my head

[ricky0115]

@mitch_350z 10mm or 1/4”

@ricky0115 alright, thanks for the info

@ricky0115 do you mean 3/8”?

Head bolts?
Or nuts. Since you shouldn't be using bolts on the head.

M10 Head Nuts IIRC.

@calum I meant the head of the bolt for the clutch bolt springs

@mitch_350z Right, yeah 10mm IIRC. I replaced all mine with M6 Stainless Steel Hex heads.
