The Durston/VIM Drain Plug Wrench, No. DPW1417, comes 16” long with offset heads for clearance. Made of a high alloy heat-treated steel with a polished chrome finish, this single wrench works with many vehicles with 14mm and 17mm drain plugs. This wrench has a 12-point box head to prevent stripping and get better grip, and makes oil changes quicker than ever, according to the company.
