ZEMO Flare Nut Head with Shoulder

Common Centre Line 36.5 mm

for dovetail torque wrenches


Shoulder flare nut interchangeable head with Sturtevant Richmont dovetail connector. Especially applicable for tightening brake hoses, oil pressure lines or control lines. Suitable for Sturtevant Richmont torque wrench series CCM and series LTC.


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!


To achieve constant torque values when changing heads, exact lever length must be maintained. Virtually all SR heads share a precise distance form end of wrench to center of fastener. This is referred to as a "Common Center Line" and is very difficult to maintain using the cut and weld construction method.




  • Five point force transmission.
  • SR dovetail connector with outstanding rigidity and wear resistance.
  • Centre line 36.5 mm.
  • Body alloy steel, black finished, head partially chrome plated.
