Frequently asked questions about Tangless CoilThread Inserts

"Are Tangless inserts as good as traditional tanged inserts?

" A major European Aerospace company had problems with tanged inserts and changed to Tangless inserts He comments:

" In order to improve this situation, alternative thread insert systems were investigated, and a complete changeover to the KATO Tangless thread insert system was made. A commonly predicted problem publicised by tanged insert manufacturers, insert retention strengths, allegedly inherent in this system was investigated and subjected to trial. These predictions were proven to be unfounded ."

"Are Tangless Inserts more expensive?"

Tangless Inserts are comparatively priced against conventional tanged inserts but in relation to total installed cost, Tangless Inserts offer considerable savings. Speed of installation is dramatically increased with no time required to locate broken off tangs.

Here's what a leading Aerospace company says - "Use of the tangless inserts has addressed the problems we were encountering completely, as there is no tang to be removed, or cause contamination, and inserts can be screwed in, or out to set depth accurately.""The use of dyed inserts has also greatly simplified and eased visual inspection after completion, and reduced the occurrence of missed inserts to a negligible level."

Installation of Tangless Inserts:

"Is any special preparation necessary for Tanged Inserts"?

Providing you use the same good working practices for preparing the tapped hole recommended for Tanged inserts, Tangless inserts can be installed just as easily. - see section " " for hole preparation details and installation advise.

Tanged / Tangless Interchngeability:

"Are Tangless and Tanged Inserts interchangeable ? Can we convert easily"?

Tangless Inserts are covered by NAS 1130 and have the same procurement specification (MIL-1-846/BS3643) and assembly dimensions as conventional tanged inserts.

Safety:

"Are Tangless inserts as safe as tanged inserts"?

Tangless Inserts were specifically developed to address the safety issue and remove the need for additional operations. Use of the tangless inserts has addressed the problems we were encountering completely, as there is no tang to be removed, or cause contamination, and inserts can be screwed in, or out to set depth accurately.""The use of dyed inserts has also greatly simplified and eased visual inspection after completion, and reduced the occurrence of missed inserts to a negligible level.

"Are Tangless Inserts appropriate to any wire coil thread applications"?

The benefits of Tangless Inserts in reducing total installation times are universally applicable. Similarly, the fact that Tangless Inserts can be colour coded to order provides for enhanced quality assurance. The safety benefits resulting from the absence of any potential debris ??? have greater relevance in specific safety critical applications.

Tangless Inserts are already being used by leading companies in a wide range of diverse markets. From space agencies and leading aerospace companies to Formula 1 Racing and major automotive manufacturers and through to Electroni, Medical and general engineering companies worldwide. We would be happy to provide references specific to your own potential applications and sectors.
