Question:

I am working on a boat trailer: So galvanized stuff. I need: square U-Bolts that fit over the 2 inch wide trailer frame, 1/2 inch in diameter and 5 1/2 inches long with nuts. I need 4 of those. And I need 1 U-bolt to fit over the 3 inch part of the tongue 5 1/2 inches long with nuts. Can you fix me up? If it matters, I have a 4,000 lbs EZ Loader trailer. I am making an accessory, not replacing existing trailer parts.

Hey Dave, thanks for reaching out. We do have a few options that will be really close to what you need. We have a 1/2" diameter U-bolt with a 2" ID part # UBZC12X212X525, but this is only 5-1/4" long.

If you need something longer we do have a 5-3/4" long U-bolt with a 2" ID part # 175211 however this is a 9/16" diameter.

Looking thru the other U-bolts we offer, I am not seeing we have a square one that would fit a 3" tongue.
