Bolt identification?

Bolt identification?

Bolt identification?

Looking to replace new bolts that were pulled out from my Toyota Hiace brake rotor that was screwed against the hub.

Having trouble identifying https://showbox.bio/ https://tutuapp.uno/ https://vidmate.cool/ grade of the bolts. Its got two radial lines on the head marking, but google research showed bolt marking of 3 radial lines only which is a Grade 5. Base on rule of thumb, grade is determine by number of lines plus two, so naturally my bolt is a Grade 4, but it doesnt exist!

RE: Bolt identification?

I think an SAE grade 5 bolt would work. (or the equivalent - after all, this isn't an American designed vehicle.)

Alternatively, go to a parts store and see if they have something for a different Toyota.

RE: Bolt identification?

Wheel and brake, try to buy the OE bolts.
I know that they will be expensive, but this is holding wheels on.
You might try searches for "JIS bolt identification"
