Professional Tool Reviews for Pros

Klein Tools D509-8 Extra-Wide Jaw 8″ Adjustable Wrench Preview

The Klein Tools D509-8 Extra-Wide Jaw 8″ Adjustable Wrench is designed with a minimally protruding jaw shank that uses a unique 4-threaded knurl worm. This gear helps balance the wrench for smoother operation and also lets you apply up to 30% more force. It includes both SAE and metric measurement scales laser etched into the jaw and the wide, plastic-dipped blue handle looks to be comfortable.


Klein Tools D509-8 Extra-Wide Jaw 8″ Adjustable Wrench Features

Even though this tool is just 8-1/2” long, it should have enough jaw capacity to handle a lot of different jobs for electricians, mechanical contractors, plumbers, and maintenance professionals. We’ve used other extra-capacity adjustable wrenches, like Chanellock’s Cap Wrench, and these really seem to a be a great option for making an already good tool a lot more useful and flexible.
