• The Adapter fits 1 inch rear hub of SPOKE WHEEL BIKE with a diameter of 1"to 1.02" (FOR SPOKE WHEEL BIKE ONLY)
• 2pcs screw 12.9Grade/W3/8-16X1" 3pcs screw 10.9Grade/W5/16-18X1"

Don't know about your's, here's an example. If yours's is countersunk that will matter on the depth plus the head depth. Take it to Ace and try out different ones. They should have it, be careful bolt doesn't bottom out when tightened for measurement.
