(8) Stainless Steel Square U-Bolts Boat Trailer U bolt Ubolt 1/2" D x 3 1/16" W x 4 5/16" L

 PartNumber: TMW12.3.4   |   Asin: B06XBJRJR2

Qty (1) = Eight U-bolts and (2) Stainless Steel Flat Washers and (2) Stainless Steel Nyon Lock-Nuts per u-bolt. These u-bolts are perfect for 3" x 3" crossmembers and axles. Use these and you'll spend less time fixing and more time boating! These 304 stainless bolts prevent rust corrosion, have 3" inches of threading, and 13 threads per inch. Look for our other listings for multiple quantities in order to save on shipping. Use of a lithium or graphite based lubricant is recommended during installation to prevent galling. U-bolts must be tightened using hand tools ONLY and threaded on correctly. Improper threading, use of power tools, over-tightening or tightening too fast will result in galling or sticking of the U-bolt.

Features

  • DO NOT USE POWER TOOLS & YOU MUST USE AN ANTI-SEIZING LUBRICANT OR ALIKE ON THE FULL LENGTH OF THE THREADS
