Bi-Hexagonal Ring Spanner

Double Open End SpannerWrench slips easily and quickly onto fasteners, and that’s particularly important for nuts and bolts in awkward places. The angle on the head allows to be used in two different positions, while an open-end spanner often gives the best access to a fastener, if it’s extremely tight the open-end shouldn’t be used as this type of spannerwrench only grips across two flats.
