Thread Pitch Measurement Needed for bolt

SixBanger · 01-10-2018, 07:19 PM

I stripped the bolt that holds down the LPFP sensor tube.

I need the thread pitch for bolt M. 13537582770 ASA-Bolt M8X17.5-AL

M8 bolts usually have 1.25mm pitch. Sometimes 1.0mm.

It's probably 1.25 pitch. Only real way is to use a thread pitch guide(or another M8 x 1.25 bolt) and match up the threads.

Hopefully you can use a tap and chase the threads clean.
