Just purchased a new led headlight for my bike. However, the kit did not include bolts. I contacted the seller and he said although pictured with bolts the kit does not include bolts. So I head in to Napa to pick up some bondo and took the light with me. These guys are stumped. He said the closest thing that fits is 8mm and it's snug. He says there's a bit of paint in the threads so that might be it. I take I home and it doesn't feel right. Measured the threads on the bolt he gave me and it's 20 count. Measured the holes threads and it looks like a match. So I figure maybe it's not metric so I do a little conversion and turns out 8mm is .06mm off from 5/16. So what do you think. Is it the bolt size or threads that are wrong. It threads just fine for a few turns then it gets snug. So snug I wasn't comfortable going any more for fear of stringing the aluminum body threads.
