Is it a 7/16-20 bolt? That's what Brey Krause is calling for but shouldn't it be metric?

Metric; if memory serves it's a weird 17mm short head.

I have found lots of seat and seat belt hardware to be SAE sizes in German cars. The seat belt bolts are 7/16-20 in the 996 and Corrado.
That said I think the 4 seat track bolts are metric. I bought some ARP bolts for my race seats. I'll look up the number later.

Thanks, if you could give me those other seat track bolt sizes that'd be great. I have a Brey-Krause harness bar I want to run but I need a few bolts to mount the front, lower legs to the car.

Seat track bolts are M10x1.5 and I used mcmaster.com part# 93700A220 which fits perfectly in the gt3/audi tt seat track.

It's 7/16-20. The only non-metric bolts on the car are the seat belt bolts.

Oh oh, I have buggered something else up.

I'm pretty sure the seat *track* bolts are M10x1.5 and the seat *belt* bolts are 7/16-20.

Ok, looks like I just need longer seat belt bolts for the brey krause harness bar. Should be able to grab them from the hardware store. Next up is seeing if I can source the harness I want in time...

All seat belt hardware is 7/16 x 20 Needs to be grade 8.8 or above. Don't skimp here.
