John,The Radius Kid:
M8x1,25x30,if memory serves.
6mm allen key.
The bolts measure close to 5/16" with a scale.
Get grade 8's,NOT stainless.
Get high temp. antisieze for the threads.
The allen key should be 6mm.
He's probably talking about 314 grade.BigMike:
What's wrong with stainless?They come with stainless and I never had a problem.I always use high heat never seize!The guy at the bolt and nut supply said they were stronger than tha G8 and also there were two strenghths of stainless. rant nono
