I just went outside and measured some 3.5 head bolts that i have lying around and they appear to be M10 x 1.25. Can anyone with 3.0 head bolts handy measure them for me? It would be most appreciated. TIA!

 

I'll measure when I get home late tonight

 

Thanks man...

 

Home yet?

 

still havent been home yet, definately will be home tonight. I'll measure and let you know.

how did you measure the 3.5 head bolts?

 

I measured the diameter of the threaded portion of the bolt then measured the distance from one thread to the next.

 

distance between threads: 1.25mm
re-measuring the diamter, dont think I measured it right.
Also going to pull out a headbolt fromt my spare 3.5 and see compare also.

 

Oooooo thanks alot. Excellent-ness!!!


I figure the diameter should be a 10mm on the 3.0 bolts as well since you need a 10mm hex socket to remove them. And if the thread pitches are identical it's safe to say i've found my answer. Thanks again.

 

no prob.
