Bolt identification

[WillyTheMLGPro]

Need help identifying a particular bolt from an L67 Engine.

Bolt is 13mm and is the bottom right one used to secure the Supercharger tensioner to the engine

Take your sample to a bolt shop. They should hopefully have one the same length. The only thing will likely be is that the size spanner needed will be a 14mm.

Actually might a 9/16 head as it might be imperial size.

Nope, 8.8 rating on head shows it is a metric bolt (otherwise would have outward dashes around circumference).

Measure bolt under head length, diameter, shank area to start of thread, thread pitch (how many mm between each tooth, or between 10 teeth and divide by 10)

Wholll, you have good eyesight. I can't even read it, hahaha. That's a pretty strong bolt. Must be an SC thing?

Yeah, apologies for the confusion, I meant they must use 8.8 because it's a SC engine. I don't remember any external bolts that size being hi-tensile on my V6?

Just take it a place that sells bolts. They will sort you out.

If the bolt shop want to supply is to long, get its nut with it. Screw the nut on before cutting it. You only need to do this trick if no good cutting the bolt & then can't get the bolt started.

Already Emailed one shop near me, Will email a few more close to me to see if they also have something similar.

Ring them!
Waiting for people to return emails, the shop doesn't have time for that.
Just use the phone (for phone calls NOT emails ).
