The front outer bolt hole for my seat has partially stripped, i’ve ran a tap down it but it’s still no good, the bolt threads in but if i try to tighten it it’s going to completely pull the threads. I’ve looked underneath the car for the nut but it’s not visible or accessible. I don’t want to drill it out to a bigger hole incase the nut breaks off. I was thinking maybe coat the bolt with some epoxy so when its screwed in it won’t work loose again. Any ideas?
Either helicoil it or drill it out and tap it for a larger bolt, anything else is just bodging it up.
if you haven't got a welder, Mike's options are sound. if you helicoil it, coat the helicoil in red loctite as you thread to where you want it to sit. I think there's enough meat for an m12 bolt but I couldn't guarantee it.
m10x1.25 helicoil kit is what you want, otherwise I'd just cut the section out, find a nice m10x1.25 nut and replace it, tacking it in with the seat bolted down, then properly welding with it back out.
drill the threads out and put a nut behind it if you can get access.
Cheers guys, gonna go with a helicoil and red loctite as i don’t have access to a welder. Should i insert the helicoil with loctite on the outer thread and allow it to dry before fitting the seat bolt or fit the helicoil and insert the bolt straight away?
For a better solution to Helicoil, look up time-serts by Wurth :)
let the loctite set before the bolt goes in, just stops the helicoil unwinding when you take the bolt out next time :)Quote:

Yeah, that's the downside, they are pretty pricey. But then, I wouldn't skimp on seat belt fixings :wack:Quote:
