DIN 3570 U-bolts

Additional information

Grade	4/6/8/10/12
Finish	ZINC, Plain, Black
Material	Stainless steel, carbon steel and other metal materials

U-Bolts are typically used for attaching pipe or steel round bar to a round wood or steel post. May be used to hang wrought iron pipe in mechanical installations and also be embedded in concrete as anchor bolts.
U-bolts support heavy objects from ceilings, walls, and poles. They are stronger than routing clamps and hangers and are corrosion resistant if made of galvanized steel or coated with zinc. Other types of U-bolts are made of aluminum for light-duty lifting, while different grades of stainless-steel U-bolts are also resistant to chemicals. U-bolts are fastened with nuts for a tight connection.
