Wright Tool 747 5-Piece 12-Point Box Wrench Set

This is a 5-piece set of 12-point box end wrenches from Wright Tool, in SAE sizes from 5/16 x 3/8 up to 13/16 x 7/8 inch. They're double offset with a satin finish and come in a denim tool roll. Wright's patented Wright Drive opening spreads the grip over more of the fastener, which helps keep bolts from rounding. The wrenches are forged, machined and heat-treated, and they meet ASME B107 standards. Wright says they're "Made in the USA" and made in Barberton, Ohio.
