A threaded insert for all materials

The Jacknut threaded insert from Torque Control is a blind fastener for use in thin, soft or brittle materials.

When tightened, the Jacknut body is designed to undergo controlled deformation, forming arms which grip the inside of the mounting surface yet retain thread alignment. This provides a permanent, deep re-usable thread

The Jacknut is produced in steel, and is offered with a 12mu m zinc chromate corrosion resistant finish which provides extended life in severe environmental conditions.
