The STEELMAN 77022 5/16-inch Side Terminal Battery Wrench is designed to help make removing and installing side terminal automotive batteries a little easier. Made of heavy-duty chrome plated steel, this wrench features a low profile ratcheting head that easily fits into tight spaces. The ratcheting mechanism is fully reversible, allowing the 5/16-inch hex head to both remove and install terminal bolts. The wrench's 6-Point head grips the sides of the terminal bolts and not the corners to prevent rounding and premature wear. The grip features a rubberized dip coating to increase user comfort and has easy to read, high-contrast white markings.
