High tensile left handed thread M8x1.0 bolts stateside?

My main crank bolt gave out on the ole yong heng. It is a 8.8 strength M8x1.0 bolt of about 20-25mm length. I cannot for the life of me find this thread pitch and higher strength in the states. I ordered some that are 12.9 strength off of amazon, but it turns out they used aliexpress to place the order!! So, it's coming on the sailboat from china, lol. Estimated to arrive in October sometime. Could be longer.



Everything I look at stateside is M8x1.25 😭
 
McMaster Carr has them. 12.9 is Allen and they have 10.9 hex head
