3/8 inch Diameter by 4 1/2 inch Long Stainless Steel Bolt

Every chance I get to replace Galvanized bolts on my Trailer, I take it and replace them with Stainless parts. Sturdy built will most likely have them stocked

as always with Sturdy the order was here in a couple of days and everything fit well. I had bought the 17" fender supports for the tandem fenders and the seamed too big, They were nice enough to except a switch to 15 " but it turned out I could use all of them depending on which side of the trailer beam I mounted them too. Fenders will now support over a 200.lb man easily

Was just the part I needed and delivered promptly!
