Hi TIm!

The Curt Lunette Ring - Adjustable Channel Mount - 3" Diameter - 12,000 lbs # C48600 uses two 5/8" Diameter x 5-1/2" long Grade 8 hex bolts, which can be found in the Curt Bolt Kit for Adjustable Channel Mounted Lunette Rings # C48620. The smaller 1/2" hardware is for mounting the channel bracket on your trailer in case you need them.

Do you already have the channel on your trailer? Figure you probably do, but also thought I should ask.
