It has been announced that Challenge Europe now carry an ex-stock standard range of metric and imperial threaded inserts for use in the manufacturing and installation industries, in order to provide a robust thread in moulded/fabricated plastic components, where the softness of the substrate precludes a tapped thread.
Threaded inserts are a favourite for use throughout industry where they can provide a quick thread just by drilling or moulding a pilot hole and pressing the insert into place, in electronic/electrical application brass inserts offer good tensile properties, excellent corrosion-resistance and good electrical conductivity.
A well-known and much used solution to fixing onto non-metals, threaded inserts can often provide higher torque or pull out performance by the application of heat or ultrasonic energy to further embed the insert into its substrate.
Expansion and self-tapping inserts are available in brass for use in plastics or in the case of wood, some composite materials and light-weight castings in aluminium or other alloys where steel and stainless self-tapping inserts can be supplied.
Inserts in die cast zinc, steel, brass or stainless steel may be push-fit or inserted by self-tapping thread cutting, others may be moulded in place.
Externally threaded inserts from Challenge Europe also include helical inserts, often used for thread repair or to provide a higher performance thread form than might otherwise be possible.
