3/4" Tohnichi SH Open End Spanner Head - 12DX3/4

The SH Open Spanner Head - SH12DX3/4

The SH type spanner heads are suitable for applications where sockets can not be used, for flare nuts in piping and for work in narrow places. Tohnichi's interchangeable head wrenches have specific diameter round ends that fit into corresponding head base openings. Head and wrench model names include the diameter sizes so heads can be matched to wrenches that will accept those heads.
