Unfortunately toolboxes are equipped to remove Penta-Bolt™ fasteners with common items such as locking pliers. Most notably, copper thieves are easily removing these fasteners. Penta-Bolt™ fasteners protecting copper should be replaced with something more secure. The savings in loss prevention can be significant.
