Is the steering column shear bolt high tensile?

Does anyone know? How can I tell?

 

I would of thought so ....bolts have the grade in raised didgets on the end ie 12.9

 

Normal bolt, when they shear they are very easy to break

 

^this. Nothing special about it - replace it with an equivalent hex-head job.

 

Cheers guys!

 

Allen key headed bolts what ya need, m8, 6'mm Allen key

 

I ground the head flat, then cut a slot in it so I can use a big screwdriver

 

Waste not, want not...

 

I am of opinion the engine being in the boot, hence a flat front no crumple zone to speak off is a coolio safe driving aid, thou I put spare on outer front panel ,that may save me?
