Thin Wall Self-tapping Inserts Tappex

 
he use of self-tapping inserts has significant advantages over pre-tapped holes, moulded-in inserts and wire thread inserts. They eliminate close tolerance holes required for tapping directly into the base material, damaged tools and low productivity resulting from moulded-in inserts and the time consuming process of placing wire thread inserts into pre-tapped holes.
For a work-piece made of a light alloy, this diagram illustrates clearly that whilst correct hole sizes are important for product reliability, the Ensat 302 achieves almost maximum pull-out with only 30% external thread interference.

Pullout Resistance
In light alloy, the self-tapping steel insert resists a pullout force in excess of the yield point of an 8.8 grade bolt.
