Thread forming in light alloys without tradeoffs

EJOT ALtracs^®Xt screws are thread forming fasteners developed for the use in light alloys as well as other nonferrous metals with a hardness up to 140 HB. When using thread forming screws for light alloys there used to be a tradeoff between clamp load and torque performance. There were either designs that achieved top results with regards to clamp load (circular screws) or designs that achieved top results with regards to torque performance (non-circular screws). With ALtracs^®Xt this compromise is no longer necessary, since it achieves top results in both categories.

Economic

Due to the omission of different process steps, the use of thread forming fasteners provides great potential for economic savings. With ALtracs^®Xt it is possible to assemble a screw joint directly into a cast geometry without further machining steps (e.g. drilling, thread cutting). With its intelligent thread design ALtracs^®Xt is able to cope with the tolerance of a casting process and provides a reliable process window even in harsh circumstances.

Smart

ALtracs^®Xt comes with the opportunity of pre-designing the thread forming screw joint via the corresponding calculation software Xt CALC^®. This software enables the calculation of all relevant process and joint parameters (e.g. torques, load levels, failure mechanisms). Thus, Xt CALC^®allows clamp load oriented design – based on the VDI 2230.

Furthermore, EJOT offers a wide range of customized engineering services. With the focus on the influence of the fastener(s) on the complete component, analyses of clamp load relaxation or leak-tightness, among others, are possible.

Compact

Due to the specific thread design for the use in light alloys ALtracs^®Xt achieves unique features. The circular cross-section of the thread creates maximum thread engagement in each thread pitch. Furthermore, the reduced flank angle of 33° (compared to a 60° flank of a standard fastener) enables ALtracs^®Xt to geometrically strengthen the light alloy part of the thread.

Those two features allow ALtracs^®Xt to generate high strength screw joints with minimum space requirement regarding boss diameter and length.
