New Profil fastener offers major cost and productivity benefits.
A new multi-purpose clinch fastener – the EMF nut – is the latest addition to the range of rivet nuts available from pierce assembly specialist, Profil UK.
The new fasteners offer a fast and extremely cost-effective method of mounting high strength M6 or M8 steel threads in pressed parts or sheet metal panels up to 2.00 mm thick (Figure 2(a) and (b)).

Through their oversize head and extended shank configuration, EMF nuts provide both high pull-out resistance and a self-centring location point for the mounting of further assembly components. In addition, they can be used to create a vital stand-off for spacer applications, such as the securing of aluminium panels to steel sub-frames.
EMF nuts are particularly suitable for automotive, domestic appliance or other sheet metalworking industries. They can be installed either through stand-alone riveting operations or – by using custom-developed, Profil automatic feeding and setting equipment – in-press as part of the component manufacturing process.
The new fasteners feature a shouldered body that is swaged and riveted into the pre-pierced base material to produce a water-proof fixing with exceptional shear and axial load performance. The fasteners' mechanical properties conform to class 8 EN20898 standards and six radial ribs are incorporated under each nut's head to ensure high torque resistance.
Standard M6 and M8 EMF nuts can also be installed within 2mm of component shoulders and at minimum centre distances of 17 and 22 mm, respectively, making them particularly suitable for restricted access applications.
