Sturtevant Richmont FN series

Common Centre Line 36.5 mm

Interchangeable Flare Nut Head with 1 7/16" Center Line

Flare nut interchangeable head with Sturtevant Richmont dovetail connector. Cast as a single piece from alloy steel. The manufacturing method provides strength and durability rarely attained by the more common "cut and weld" method. SD square drive heads are ideal, when:

  • Working on pneumatic, hydraulic or other connections involving tubing,
  • There is not room to fit an OE or ROE head into the space at the connection.

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.

 

Features

  • 30 degrees opening offset
  • SR dovetail connector with outstanding rigidity and wear resistance
  • Centre line 36.5 mm
  • Cast Alloy Steel, black finished
