It's an M8x1.25 30 mm long bolt. The 8.8 is the grade for metric bolts.
In the land of metric, we don't even bother to mention the pitch (1.25 in this case), only if we actually want a fine thread or something. So we would just call it M8x30 mm bolt.

Thanks for that post and picture. I had no idea on the tensile strength of the metric 8.8 being so much lower than a grade 8 SAE bolt. Seems the metric is about a grade 3 in SAE. Need a grade 10.9 metric to equal a SAE grade 8.
