measure the hole. About 1/4 inch is a 6mm bolt. About 5/16 inch is 8mm. About 3/8inch is 10mm. 10mm bolts have 2 common threads: 1.25 and 1.50 (mm per thread) (American is threads per inch). So buy 4 bolts at your hardware store and see what fits. Home Depot sells an American / metric steel 6" ruler for a couple dollars. A GOOD investment.
