U-Bolts
Available21 products
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.

Standard U-Bolts
Standard U-bolts (or round U-bolts) attach pipes or round steel bars to wood or steel posts. They may also hang pipe from walls or ceilings or may be embedded in concrete as anchor bolts. They are stronger than routing clamps and hangers. U-bolts are fastened with nuts for a tight connection. Black oxide-coated U-bolts are corrosion resistant in dry environments. Zinc-plated U-bolts are corrosion resistant in wet environments. Hot dipped galvanized steel U-bolts are corrosion resistant, stringer than regular steel and are resistant to abrasion. These U-bolts are also available in lightweight aluminum or naturally corrosion-resistant 304 or 316 stainless steel.

Standard U-Bolts with Mounting Plates
Steel U-bolt mounting plates attach to U-bolts to fasten objects to ceilings or walls. The mounting plates allow the U-bolts to hold heavier objects than just a nut provides. Mounting plates come in a black oxide finish, which is corrosion resistant in dry environments, a zinc-plated finish, which is corrosion resistant in wet environments, or can be hot dipped galvanized for extra protection in wet environments. The U-bolts are also available in 304 stainless steel.

Square U-Bolts
Square U-bolts suspend flat-bottomed objects from ceilings and walls. U-bolts are fastened with nuts for a tight connection. They are stronger than routing clamps and hangers and are corrosion resistant if made of galvanized steel or coated with zinc. Zinc-plated U-bolts are corrosion-resistant in wet environments. These U-bolts may also be hot dipped galvanized for extra corrosion resistance. Other types of U-bolts are made of aluminum for light-duty lifting, while 304 stainless steel U-bolts are also resistant to chemicals.
