ZEMO Special Box Head (S-BH)

Common Centre Line: 3 7/8 inch (~98.4 mm)

for dovetail torque wrenches


Special manufactured interchangeable box head with Sturtevant Richmont dovetail connector. Suitable for Sturtevant Richmont clicker type torque wrenches CCM-400 and CCM-600 or series LTC. S-BH box heads are ideal, when:


  • A socket cannot be used,
  • The entire hex of the fastener or fitting can be engaged,
  • A high level of head strength (torque level) is needed.


The unique SR dovetail design used to join head and wrench provides an exceptionally strong connection and allows complete interchangeability. The SR system contributes to both operational flexibility and enhancing your return on investment!




  • Double hex point force transmission
  • SR dovetail connector with outstanding rigidity and wear resistance
  • Centre line 3 7/8 inch
  • Alloy Steel, black finished
