Adjustable Wrench Takes Quick Measurements

Have you ever had trouble identifying the correct drill bit size for boring holes for dowels, bolts or pipe? If you don’t own a caliper, all you really need is an adjustable wrench. Close the jaws of the wrench around a dowel or bolt, then match the bit to the jaw opening. While it’s no vernier caliper, the wrench still works quite well.
