Screw thread steel bar in small
diameters can be bent into U shape, L shape and other shapes through
manual force by most people of average strength, while screw thread steel bar
in large diameters should be bent by typical machines. Bending steel
can be accomplished either through using heat or through using manual
force.
Instructions
1. Determine the dimensions of your
bolt. A U-bolt will have two straight legs of equal length connected by a
bend. Determine the length of the straight leg of the bolt. Mark the
length on the screw thread steel bar and screw a nut on the rod until it
reaches the mark.
2. Secure the screw thread steel bar in
the vise. Use a vise that is securely mounted to a workbench. Clamp the
rod so that the jaws of the vice squeeze the nut, not the threads of
the rod.
3. Align the nut so that it is level
with the top of the vice. Tighten the vice so that the rod is firmly
secured in the jaws of the vice. Do not allow the jaws of the vice to
mar the threads of the rod.
4. Bend the rod using using a steel
pipe. Slide a steel pipe over the outside of the rod. The pipe should be
just slightly larger in diameter than the steel rod. Allow the pipe to
slide down until it hits the top of the vice and the nut. The pipe
should be one to two feet in length in order to provide sufficient
leverage.
5. Wear safety glasses. Grab the pipe
and push downward with steady pressure until the screw thread steel bar
begins to bend. Continue pushing until the rod is bent into a U-shape.
