To carry out thread repairs or create threads in non-tappable materials, threaded inserts are essential. The internal threads found in soft materials such as light alloys, plastics, and compressed wood are often vulnerable to repeated stress. In case of excessive or frequent tightening, the threads may tear, making the part unusable.
That's where self-tapping inserts come in. By creating their own thread once installed, our Intervis inserts become firmly anchored in the metal, thus avoiding any need for pre-tapping, unlike other threaded inserts. This method provides increased holding power when loosening.
Threaded inserts consist of a standard thread and a suitable external thread, including an external thread truncation and two slots with sharp edges.
All of this means that the insert can be screwed directly into a smooth, pre-drilled hole, like when using a tap.
Gardette Industries is proud to offer the Intervis®-brand threaded insert, an innovative (internally and externally) threaded insert developed by LGC Industries, a P3G group company. Intervis threaded inserts offer a practical solution for tapping and screwing since they can be inserted directly into a previously drilled hole. Thanks to their ability to make their own thread, these inserts ensure additional safety and strength.
We recommend that you use Intervis threaded inserts in aluminium assemblies, as their surface treatment eliminates the electrolytic couple between the two materials. The drilling groups serve as an average indicator only, and during installation, a drilling test 1/10th above or below the indicated diameter is recommended in order to take certain materials' specific features into account.
Intervis® threaded inserts offer several advantages, including installation without pre-tapping, eliminating the gap between the spacer and the component, excellent pull-out resistance, maximum holding power at 30% to 40% engagement, no more abrasion / wear from tapping, as well as absolute safety of use.
Here at Gardette Industries, we offer various ranges of Intervis® threaded inserts in various materials such as crude steel (SCTA), chromium (VI)-free case-hardened zinc-plated steel (SCT), brass and stainless steel.
Standard Intervis threaded insert
The standard Intervis® threaded insert fits directly into a pre-drilled hole. It acts as a tap by carving its own thread in the hole, making it an ideal fastener for medium-hard materials such as light alloys, compressed wood and plastics. It is easy and efficient to install.
Intervis 3-hole threaded insert
For low-height Intervis® STHC threaded inserts, three holes have been added to the self-tapping insert to allow chips to escape more easily when tapping the assembly material.
In short, the 3-hole Intervis® SCTH threaded insert is a practical alternative to standard 1-slot Intervis® inserts for smaller heights and thicknesses.
