Bolt cross reference, part number to size?

Is there any way to cross reference a bolt part number to find the size/thread of the bolt?
I need to do some work on my 98 3rd gen 4runner and I'd rather not wait 2-3 weeks to get a handful of bolts from Toyota when I can get them in 2-3 days from my local Fastenal. I could take the bolts out to measure but then my truck will be down for days. Part number don't give any indication of size (91512-61030) so I was hoping someone had a way to decode or a way to find the size.

Thanks,

Matthew

No real way to tell other than measuring. Good luck.

Thanks, I have a pretty decent metric set but it always turns out that I need an odd ball length that I don't have.

Just which bolts do you need ??

M8x1.25 M10x1.25 m12x1.25

M6x1.00 then just guess at the lengths you need

I can get most all Toyota Hardware in 2 days unless it is really strange from my local dealer

Maybe your in the great White North ??

Unless things changed I never was able to get JIS bolts at Fastenal best of luck

The p/n usually, although not always, has the the thread size in the first few digits of the second half of the p/n. For example, the LBJ bolts p/n is 90105-10406. The size is M10. Works with nuts and washers, too. Then Toyota makes the pitch easy, as they only use one pitch for thread size, to wit:

6 mm diameter - 1 mm pitch (iso course) - requires 10 mm wrench to fit head / nut
8 mm diameter - 1.25 mm pitch (iso course) - requires 12 mm wrench to fit head / nut
10 mm diameter - 1.25 mm pitch (iso fine) - requires 14 mm wrench to fit head / nut
12 mm diameter - 1.25 mm pitch (iso other) - requires 17 mm wrench to fit head / nut
14 mm diameter - 1.5 mm pitch (iso fine) - requires 19 mm wrench to fit head / nut
16 mm diameter - 1.5 mm pitch (iso fine) - requires 22 mm wrench to fit head / nut
So the LBJ bolt is M10x1.25mm.

Length you are on your own.

The p/n you posted is also likely a M10x1.25, going by the second and third digits of the second half. I'm still playing with this revelation, but it works more often than it doesn't.

More detail and other excellent info in this post:
