Qty (1) = Four U-bolts and (2) Stainless Steel Flat Washers and (2) Stainless Steel Nylon Lock-Nuts per u-bolt. These u-bolts are perfect for 3" x 3" cross-members and axles. Use these and you'll spend less time fixing and more time boating! These 304 stainless bolts prevent rust corrosion, have 2-1/2" inches of threading (2.5"), 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 SS Locknut.

Use a hand wrench or socket ratchet when installing nuts. DO NOT USE an impact or a high speed socket driver.
