Usage Scenario

Mark was assembling a metal shelving unit for his garage. The exposed screw threads on the bolts were sharp and could easily scratch his arms or snag on boxes. He slipped a black rubber cap onto each bolt end. The soft PVC material gripped the threads firmly, covering the sharp points. Now the shelves are safe to use, and the caps also keep dust and moisture away from the metal.
