Tie Down Engineering Square Marine U-Bolts, 1/2 in.-13 Thread, Pair - Available in 3-1/8" x 3" to 4-1/8" x 3"
Tie Down Engineering Square Marine U-Bolts, 1/2 in.-13 Thread, Pair - Available in 3-1/8" x 3" to 4-1/8" x 3"
Tie Down Engineering's square marine U-bolts are built for mounting roller brackets, bunk brackets, and other square stock hardware on boat trailers exposed to saltwater, freshwater, and road spray. Each U-bolt is formed from 1/2 in.-13 threaded rod bent into a true square profile so it seats flush against square bracket channel instead of rocking against round tubing. Corrosion-resistant plating stands up to marine environments, and every U-bolt ships with the mounting hardware needed to bolt it straight to your bracket. Sold in pairs, this line covers the common bracket widths and depths used on trailer roller and bunk assemblies, so you can match the U-bolt to your bracket's exact footprint instead of forcing an oversized or undersized fit.

Sizes & Options
All three U-bolts in this line share the same 1/2 in.-13 thread size and square profile, differing only in their length x width dimensions. Measure your bracket's opening (the inside span the U-bolt needs to clear) and its depth before ordering: the 86204 fits a 4 in. x 2 in. bracket, the 86205 fits a 3-1/8 in. x 3 in. bracket, and the 86207 fits a 4-1/8 in. x 3 in. bracket. Double-check against your existing hardware or bracket spec sheet, since a mismatch of even 1/8 in. can leave the U-bolt loose or unable to seat.
