Clean Threads: Cutting and Grinding Threaded Rods

Cutting threaded rods with a sharp hack saw is easy. The problem starts when you try to screw a nut on the cut end of the rod. The burr left by the hack saw makes it almost impossible to get the nut started. To avoid the problem, screw two nuts on the rod before you cut it. Then follow these steps:

After cutting the rod, grind or file the end of the rod flat (Step 1). The nuts on the threaded rod now will allow you to easily re-cut the threads. First, one nut is removed to draw the burr outward (Step 2). Then, a light rotation against the wheel will take most of this off (Step 3). Finally, the second nut will clean up any leftovers, as in Step 4.
