Pivot, type P11

The  P11 pivot is a bi-metal construction. The body is constructed from Brass, whilst the tip is made of highly polished Iridium or Tungsten Carbide. The pivot is manufactured to close tolerance to enable it to give good service in  its working environment. An 8BA Brass nut is supplied with this pivot.

A typical application for this pivot would be for use in instruments or navigational compasses (i.e. Mk 3 Liquid Prismatic Compass).
