Description

Ensat Inserts – Performance Details The 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. The use of a self-tapping insert can result in a reduction in thread size required because of the insert’s large effective shear surface saving material and reducing cost and weight. Tappex Products Ensat Screws External Thread Interference 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. Installation Procedure Drill hole to correct diameter, countersink if necessary. Screw the Ensat onto the driving tool with the cutting slot or cutting hole pointing downwards. Ensure that driving stud engagement into the Ensat does not exceed half the height of the cutting slot or hole Ensure that the insertion tool and Ensat are perpendicular to the hole. When using a production driver (029 series), the rotating shell must rest against the externally visible stop pins in such a way that it is driven round clockwise by the pins. Set depth control, where applicable, to 0.1/0.2mm below the surface of the receiving material.
