Aluminium tapping is an operation that is conducted in addition to aluminium drilling in order to create a thread in a hole for assembly purposes. Depending on its direction it may be possible to incorporate the screw port into the aluminium extrusion design.
The ease with which aluminium alloys can be drilled or punched and the incorporation of screw ports in the extrusion has encouraged the use of stainless steel self-tapping screws as the standard method of joining, particularly in the window and door industries.
Screw ports are rarely fully enclosed as the use of a 60 degree opening gives a large improvement in extrudability with only a small reduction in pull-out strength.
It is important to establish at the design stage the correct port diameter for the screw size you are planning to use. Our sales team are on hand to offer advice on this or any other aluminium fabrication requirements you may have.
