Ensat® Self-Tapping Insert Guide

The Ensat® is a self-tapping metal insert, with internal and external thread and slots or holes providing a tapping effect.

The Ensat® bush is installed into materials with low resistance (such as alloys, plastics and castings) requiring threaded seats with high specifications of resistance and wear. They can also be used for re-tapping worn thread.

The Ensat 302 bush (with tapping grooves) is ideal for use with most applications.

The Ensat® bush may create a slight self-locking effect with some materials.

If this is not required, we recommend the Ensat 307-308 series (with tapping holes), whose shape is ideal for materials that are particularly resistant to cutting.

The Ensat 307 series is short and compact and is particularly suitable for low thicknesses.

The Ensat® bush can be used for all machining and processing of plastics.

The Ensat® bush has a large cutting surface and therefore offers greater resistance to traction. It can be inserted into the finished item, which means higher efficiency for machining centres and the elimination of positioning errors or material deposited in the thread.

A casting hole or tool with standard tolerances is all that is needed to fit Ensat® bushes. Its fast and easy fitting makes the system extremely cost effective.

Ferrous and non-ferrous metals, light alloys, cast iron, brass, plastics, resins, soft thermoplastics, wood and derivatives, materials designed for threaded housings.

Ensat bushes allow use of smaller sized screws or tension rods to achieve the same resistance to traction.
With light alloys, Ensat bushes provide maximum resistance to traction with just 30% of side coverage.
