Self-Tapping Thread Inserts In Steel Stainless and Carbon steel

Self-tapping thread inserts in steel stainless and carbon steel are screwed into preformed or predrilled holes and cut their own threads into the wall for permanent installation. Eliminates the time and expense of tapping. Provides a strong wear and vibration resistant thread. The steel inserts are hardened with a zinc and clear chromate finish. Stainless are type 303. Can be installed with hand installation tools. Hole size listed is for reference only. Optimum hole size to be determined through experimentation. A 60 degrees countersink is required for flush mounting. For use in aluminum, aluminum alloy, magnesium and mild steel.

It is suitable for installation in the following materials:

- Light alloys

- Cast iron, brass, bronze NF metals

- Plastics, laminates

- Hardwoods

Manual installation:

Manual driving takes place using the driving tools 620, 621 or 610 and a tap wrench:

1. Drill the hole: see page 6 for the correct diameter, countersink if necessary.

2. Screw the Ensat onto the driving tool with the cutting slot or cutting bore pointing downwards.

3.Drive in the Ensat until appr. 0.1 -0.2 mm below the surface of the workpiece. When using tool 620 and 621,the rotatable shell must rest against the externally visible stop pins in such a way that it is driven round clock- wise by the pins.
