TAPTITE 2000®: History and development

The chipless thread forming process was introduced in 1961 with TAPTITE® fasteners as a worldwide standard. Later developments like the TAPTITE® II and the DUO-TAPTITE® fasteners addressed ever increasing technical requirements.

Now the new TAPTITE 2000® fastener combines the technologies of the TAPTITE® II and the DUO-TAPTITE® while further enhancing the thread profile.

It is no wonder TAPTITE® fasteners are the worldwide number one choice for thread forming applications.

TAPTITE ® II This widely marketed thread forming screw for metals has a chamfered edge over the first three and a pronounced Trilobular® form.

DUO-TAPTITE ® The special thread forming screw for applications over M5 has a less pronounced Trilobular® form in the load-bearing threaded area, and offers a much greater resistance to stripping out, and thus a much stronger joint. The tip profile with two stabilising thread helps to ensure perpendicular insertion.

TAPTITE 2000® The different properties of the TAPTITE® II and the DUO-TAPTITE® fasteners are combined in the TAPTITE 2000® and further enhanced with the special Radius ProfileTM thread . This means even lower insertion torques an higher pre-tensioning strength, while the conical tip over the first 2 to 2.5 thread turns (SPTM version) decisively improves insertion.
