The new ALtracs Plus also offers additional safety in the assembly process because of multiple repeat assemblies. This produces an improved ‘start’ to thread forming and a centred alignment, even in cast holes with handheld assembly tools.

The metric pitch and the specific 33° thread flank of the ALtracs® Plus leaves a larger thread root in the ‘weaker’ female thread of the light alloy.

The objective of this improvement was to obtain a self-tapping fastener, with assembly parameters similar to a conventional metric 10. In case of repair, a metric screw is completely interchangeable and can be fastened into the tapped hole. The use of other, for example torque/rotation angle controlled fastening methods, is also unproblematic.

For that reason thread forming in light metal will become more and more important for the market, especially with challenging designs..New generation of thread forming screws for light alloy 03 February 2015 In modern assembly lines cost saving and component optimisation are decisive competitive factors.9 machine screw.

The DIN7504K cross section, in combination with various installation depths (1mm to 2.5mm x d), enables a high amount of flexibility in the choice of the appropriate fastening system. The thread flanks in the screw point are smaller in diameter just like the previous ALtracs geometry, but the ‘Plus’ is also tapered to the front
