Clinch bolt has dual functions
A versatile clinch bolt the shank of which has a trilobular (triangular) shape provides a releasable connection, a permanent connection or a combination of both.
'Time is Money', this old saying has prompted the Arnold Umformtechnik engineers to Develop a fastening element which has never been seen before Connections which can be released, are normally made by means of threaded parts, like screws, bolts, and nuts, permanent connections are made by welding, gluing, joining, or riveting

Fastener gives anti-cross threading geometry
A spherical point at the end of a rotating fastener's shank locates the tapped hole and provides proper alignment to ensure a positive thread engagement.
Thread forming screws make assembly easier
Thread forming screw geometry allows the mating material to flow much easier and closer to the core of the screw, at a much reduced installation torque and giving an improved clamping force.
A fastening element which can provide a releasable connection, a permanent connection or a combination of both has been developed at Arnold Umformtechnik.
The ATP Arnold TriPress is a very versatile clinch bolt the shank of which has a trilobular (triangular) shape.
Depending on the load to which the connection is subjected, the shank can either be given a longitudinal knurl, or have lateral grooves, or a combination of both.
After clinching the shank the torque and clinch strength is considerable, in most cases exceeding the break moments of a conventional fastening element.
For turning a permanent connection into a releasable connection there are two variants, the version with centre collar or the version shank with thread connection.
Both versions allow the user after clinching the stud in a normal way to attach further component parts by means of a nut.
There are many applications in which this fastener can be used.
These include applications in generator or electric motor casings, and for connecting plastic parts and aluminium sections together.
The cost-effectiveness of such fasteners results from minimum clinching times (10% compared with screwed connections) and simple and reliable handling.
