Reference the 6mm bolt- as the fork in question uses 1/4 bolts i have checked with the S A E bolt charts and have found the following, 1/4 x28 tpi (unf) bolt will break at a minimum 4,368 lbs in tension, 5,024 lbs in shear. this works out to be-1.95imperial tons and 2.9125 tons respectively. so, according to "the book" my estimate of 1 ton is well within the safety limits of the accredited body. From experience, provided that the thead engaged is at minimum twice the diameter in depth when screwed into aluminium it will function without problems! As there are 2 bolts per side this is doubled, i doubt even a moto g p rider could generate such forces in this area!
