Thread forming slashes costs by 88%

Taptite 2000^® generation of thread forming screws combines efficiency advantages with process reliability. A total cost saving of up to 88% can be achieved in threaded fastener assembly.

The Taptite 2000^® generation of thread forming screws from Arnold Umformtechnik GmbH & Co. KB makes a fundamental contribution to cost reduction in threaded fastener systems (Figure 1). Based on experience, costs savings of up to 88% can be achieved in threaded fastener assembly.

According to the results of various studies, 85% of the total cost of a conventional threaded fastener joint arises from secondary costs such as drilling, thread cutting, inspection, tools and workstation cleaning. The actual fastening components account for only 15% of the total cost.

Here the thread forming screws of the Taptite 2000^® generation offer decisive efficiency advantages, since costly assembly processes can be eliminated when these fastening components are used. In particular, non-cutting formation of the nut thread with Taptite^® products makes them true ‘cost killers’. Furthermore, downstream operations such as cleaning and inspection are no longer necessary. Drilling operations can also be eliminated with pre-cast core holes, thus allowing total cost savings of up to 88% to be achieved in threaded fastener assembly.

Taptite 2000^® users also benefit of the improved mechanical properties of the assembled joint. The trilobular shank form and radius-profile thread flanks result in around 50% lower thread forming torque than with conventional thread forming screws, which translates into higher clamping force together with a smaller statistical spread of clamping forces.
