Still available from Tradition

It's M18x1.5, 65mm long but unless it's damaged it can be re-used

Hi Mike,

Is this a stretch bolt?

Regards

George

If it can be re-used it won't be a stretch bolt.

**Tractor Dave** · 20 July 2021, 15:29

It's a tough one. 12.9 grade. Avoid the febi copy as it has a much thinner collar.

Should the bolt be used with a washer / diamond washer ?

Yes. Still available from ebay.de if your old one is damaged.

As John has hinted at, it's not a stretch bolt. Tightened to 450 Nm

Could be worth getting some custom ones made to the correct dimensions. Any interest?

**gvr** · 26 July 2021, 10:28

I agree, I will be interested should their be other members who agree.

The same for the SWAG one? I was checking for 3b s2, Febi and Swag both popped up in the webshops.
