Roll bar bolt threads

[Corporal6531]

I took the top off my 89 a few weeks back and noticed the threaded holes on both sides of the roll bar. Does anyone know the thread dimensions? I'd like to use them for beach fishing as a type of outrigger rather than buy a fishing rack for my trailer hitch.

I believe it's a m10x1.25

Cool

Thanks

They're seat belt bolts, same size as your fronts.

I think they're 7/16-20.

It's a standard size for seat belts here in the US.

If that's the case then they're a M12x1.25, but I thought they had a 12mm head on the bolts. If they had a 12mm bolt head then they would be a m10 diameter and I'm pretty sure the pitch is 1.25.

They're not standard. Everything on these runners are metric.

I used this thread when I installed rear shoulder belts into my '88 4runner...

Note post number 21.

I ordered from the same vendor and the bolts I received were 7/16 and fit perfectly.

I know for sure they're the same pitch as the front seat belt bolts. If I remember right, the front bolts have a 12mm head, but don't quote me on that.

The front seats and seat belts are a 14mm bolt head on the 1st gens, same for the 2nd gens too. If the bolt head is a 14mm, then the thread diameter is -2mm from the bolt head size. The most common pitch for our runners are 1.25, there are few that are 1.0 and 1.5.

OP: If you go and get one 12mm and one 10mm diameter with a 1.25 pitch, one of them will fit
