Stainless Steel U-Bolt 1/2 inch x 3 inch x 4 5/16 inch Trailer U-Bolt
Price: $8.15
In Stock

Stainless Steel U-bolt measuring 1/2 inch x 3 1/16 inch x 4 5/16 inch, Used to hold on various brackets on boat and utility trailers.  Includes Stainless Steel nuts, Locking washers, and flat washers. 

Specs:

Finish: Stainless Steel

Thread Size:  1/2-13

Inside Width: 3 1/16 inch

Inside Length: 4 5/16 inch

This U-Bolt size is the most commonly used boat trailer U-Bolt. The most common tubing that this U-Bolt would mount around would be 3" x 3" tubing. For example, using this U-Bolt with the Galvanized Vertical Bunk Brackets L Type or Swivel Top Boat Trailer Bunk Brackets would allow you to mount your bunk brackets to your trailers cross-member. In addition, this size U-Bolt would mount your Boat Trailer front V-Guide or Galvanized Boat Trailer Roller Brackets to your trailers cross-members. 

Using this Stainless Steel U-bolt is ideal for aluminum trailer parts like cross members and Aluminum Vertical Bunk Brackets L Type

Mr
Though I have not yet installed my rebuilt trailer bunks using these U-Bolts, they appear fine. In addition, these were the best price I could find I could find for the SS U-Bolts (plus connection HW) on the internet. BoatTrailerParts also was very prompt in their shipping. I will be checking with this vendor for all future parts I may need.

I got these to mount a winch seat to a winch post, ultimately to be used for a winch setup on a raft trailer. These were fine, fit perfect, got here fast.

I have used BTP four times to purchase replacement parts for my boat trailer that needed replacement or upgrades after 15 years of use. Trailer now looks brand new and I have the confidence to go anywhere. Each time I have used BTP, the sale reps have been knowledgeable of products and very professional to deal with. Products were delivered as promised and were always of the highest quality. I would strongly recommend using BTP if you have trailer maintenance needs.

Stainless steel square u-bolts
These square stainless steel u-bolt and nuts are perfect for my application. You get the best of both world's, no rust and strength. U-bolts by their very nature tend to rust at contact points but not these babies. Stainless steel u-bolts may cost a little more but in the long run your better off. Good valve for the money!

Parts arrived pretty quickly, were the correct quantities and were good quality. They fit great and as most know, removing the old parts was the worst part of my trailer rebuild.
