FOCMKEAS 4 Sets 304 Stainless Steel Square U-Bolts 2"(50mm) Inner Width, 3.15"(80mm) Length Stainless M6 with Nuts, Frame Plate, Accessories for Automobiles Trailer, Boat Trailer Industrial Parts

The stainless steel U-shaped bolt is made of high-quality high-grade stainless steel. Even if there are serious scratches and bumps on the surface, it will not affect its corrosion resistance, because its surface is not coated at all. The quality determines that it is the same from the inside out. The 304 stainless steel U-shaped bolt with a higher rust-proof level has a longer service life under the conditions of sun exposure and high coastal salt. It is recommended to use lubricant during installation to prevent wear. Use a hand wrench or socket ratchet when installing the nut. Do not use a high-speed power tool or impact tool to tighten the nut. 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 nut.
