Product Description
This package includes (4) Stainless Steel U-bolts and (8) Stainless Steel Flat Washers and (8) Stainless Steel Lock nuts. These U-Bolts are made in the USA out of high quality 304 Stainless Steel, and they along with the 304 stainless hardware included, hold up well in wet/salt water environments. The 3-1/16" width is the clear Inside measurement between the "Legs" of the U-Bolt. The 5- 5/16" Height is the inside dimension measurement from the top inside of the "U", to the bottom tip of the "Leg". ATTENTION: To determine the Height of the U-bolts You need, measure the total height of the metal and members to be "clamped" and add 1" for the nut and washers. To prevent "galling" (also known as "thread lock") use a hand ratchet or wrench to run up and tighten the nuts, do not use a an impact or powered socket driver. If a U-bolt is accidentally dropped in sand, thoroughly clean it and apply lithium grease to the threads to prevent galling. These U-Bolts will fit on 3" x 3" cross members, such as 3" x 3" box steel. Look at our other listings for multiple quantities in order to save on shipping. Magnetism: In its originally formed state 304 stainless steel is Austenitic and not attracted to a magnet but when threads are machined into the 304 U-bolt rod and the bends are formed, those areas become slightly magnetic, but they are still corrosion proof. When a 304 u-bolt is placed on a smooth surface, a strong Neodymium magnet placed at the bend of the u-bolt is able to slide or move the u-bolt, but it won't be able to lift it up off of the surface (Grade 201 Stainless Steel u-bolts can be lifted up off of the surface with the same Neodymium magnet). Grade 304 Stainless steel is also referred to as "18/8" because it contains 18% Chromium and 8% Nickel which is twice the amount that is in it's less expensive, and less corrosion resistant cousin Grade 201.
