Hey Nicole! The Demco Trailer Coupler # DM69FR has 5/8" bolt holes so the Hardware Kit for Demco Adjustable Channel Mount Couplers # DM6166 will fit. Demco calls for grade 5 bolts in the manual, so as long as these are long enough for your application (1-3/4" long) they will work as mounting hardware.
What are you setting the coupler up on?
