Abstract:
A one piece, wrench head having an open end for a fastener having at least two substantially parallel outer engaging surfaces creating an across-width dimension; said wrench head having an orifice comprising six principle internal engaging surfaces each being substantially flat and positioned around an imaginary central axis with the first, second and third internal engaging surfaces being positioned on a first jaw, and the fourth, fifth and sixth internal engaging surfaces being positioned on a second opposing jaw, said first internal engaging surface being positioned closer to said open end than said second internal engaging surface and diverging outward from said imaginary central axis, said second internal engaging surface being positioned closer to said open end than said third internal engaging surface and being substantially parallel to said imaginary central axis, said third internal engaging surface diverging outward from said imaginary central axis, said fourth internal engaging surface being positioned crosswise opposing said first internal engaging surface and diverging outward from said imaginary central axis, said fifth internal engaging surface being positioned crosswise opposing said second internal engaging surface and being substantially parallel said imaginary central axis, said sixth internal engaging surface being positioned crosswise opposing said third internal engaging surface and diverging outward from said imaginary central axis, and, said second and fifth internal engaging surfaces being spaced apart by a dimension slightly greater than the across-width dimension of said fastener, said first and sixth internal engaging surfaces being spaced apart by a dimension slightly less than the across-width dimension of said fastener and said third and forth internal engaging surfaces being spaced apart by a dimension slightly less than the across-width dimension of said fastener.
