Hi Bart!
When you install the SwingKing Bolt-On Swing Tongue Kit - 3x5 - Galvanized # TD93FR, you want to use qty.4 grade 5 (minimum) 1/2-13 hex bolts. With your your trailer's frame being 5" tall, you will want 6" long bolts, but you will also need to grab eight 4" long hex bolts for the side bolts. And you will need nuts for the bolts, of course. I tend to use lock nuts for this kind of thing (specifically nyloc), but you could use standard nuts with lock washers as well.
Are you wanting to put this on a boat trailer? It tends to be what most people use this type of thing for, but you never know. : )
