Countersinking facilitates the installation of an inserts by providing a lead for the first thread. CoilThread Inserts do not have a Class of Fit associated with them. Tangless CoilThread Insert installation is now complete.
CoilThread Inserts are designed to be installed into thread profiles which conform to NASM Assembly and thread dimension specification. KATO recommends countersinking a hole where allowable. KATO recommends the following procedure to ensure the best installation and function of a CoilThread insert. If the finished tapped hole gages satisfactorily, the installed insert will be within the thread tolerance when the insert meets the drawing requirements.
Installation Procedure
Follow the instructions accompanying the installation tool for proper insert installation. NASM states "Accuracy of the finished thread, when the insert is installed, is dependent upon the accuracy of the tapped hole. KATO recommends the tang always be removed to ensure that the full threads of the bolt fully engage the locking coils when using locking inserts. After the insert is installed, the GO thread plug gage may not enter freely because the insert may not have been fully seated in the tapped hole; however, the insert should become seated after a bolt or screw is installed and tightened.

A proper STI thread is paramount to creating a precise finished thread profile. It is very important step to verify the dimensions of the STI threads before attempting insert installation Why Gaging Matters?
In blind holes it may be necessary to remove the broken tang from the bottom of the hole recommended. These should be noted as such when designing or reading a print. Tanged inserts require removal and retrieval of the tang, continue to step 6. The tapping depths given are the minimum full thread values. The suggested drill will depend on the size of the STI thread being created and the parent material.

To achieve maximum assembly strength the bolt must engage the entire insert length. KATO has found this eases installation, prolongs the life of the installation tool, and has a negligible effect on the strength of the fastener assembly. Gaging should be nasm35337 after any finish or plating is applied to the STI threads. It is, therefore, not necessary to gage the installed insert. If additional copies of the instructions are needed please visit KATOpedia instructions. The diameter of the countersink is dependent on the nominal size of the STI thread being created.
