PROTO Refrigeration Wrench 1/4" x 3/8" Square & 3/16" x 5/16" Square - J1112

These ratcheting box-end wrenches, also known as HVAC wrenches or refrigeration wrenches, have a 4-pt. box end design that allows more contact with the fastener's sides than a 6-pt. or 12-pt. style and prevents rounding the fastener's corners. They can be used on square fasteners and have a 4-in-1 style that allows the wrench to be flipped over to access a total of four different SAE (inch) size fasteners. The ratcheting box ends have a gear mechanism that allows the wrench to rotate freely in one direction without removing the wrench head from the fastener and repositioning the wrench. Box-end wrenches can access valves on residential and commercial refrigeration units.
