Product Description

Leader-Fastener® Round Bend U Bolt have two threaded arms connected by a u-shape bend. Round bend U-Bolts have a broad range of industrial industrial applications. They are typically used for attaching pipe or steel round bar to a round wood or steel post, or to hang wrought iron pipe in mechanical installations. U-bolts can be embedded in concrete as anchor bolts. Round bend u-bolts can also be used for leaf spring truck and trailerapplications.

Round shape U-bolts can be bolted on to an existing bracket or combined with a mounting plate for a secure hold on the mounting surface. U-bolts are a sturdier fastening solution than routing clamps and hangers.

Whatever the application, the signature U-shaped bend in the bolt keeps it in place. The bend provides a sturdy joint for frame fastening, foundation or roof anchors, wire and cables, piping support, conduit support, and finally motor and engine components.
