Fitting Instructions for wire inserts

1. Drill hole to the diameter and depth as specified.
2. Tap the thread to the correct depth & fit classification as specified, using the correct STI taps.
3. Gauge the tapped hole using a Go / No-Go wire insert thread plug gauge.
4. Install the insert to the desired depth using the correct inserting tools.
5. After installation remove the driving tang from the insert using the correct size tang break punch. A sharp hammer blow will shear the tang at the break off notch with out moving the insert.

Drilling
Clear the damaged thread with a Standard Drill.
Up to M 12 (1/2") the KITS include the correct drill.
To repair a spark plug thread no pre-drilling is necessary if using the special Spark Plug Tap. Please pay attention that for Fluteless Taps bigger holes are required.

Check
Check that thread and pitch of the tap and the bolt match.

Tapping
Use the special V-COlL-Taps for cutting the
holding thread into the cleared hole.
It is recommended to use a suitable cutting oil.

Install the Insert
Place insert on Installation Tool and position the adjustable ring so that the insert tang is centred in the tang slot.
Wind the Insert in with a light downward pressure until a half turn below the surface. Don't work against thread direction as the tang could break.

Tang Removal
After finishing lift the Installation Tool and use the Tang Break Tool to remove the tang. For bigger sizes and Spark Plug Taps use Long Nose Pliers to remove the tang.
Due to the narrow and exact tolerances the new thread normally is stronger than the original one.

Application:

Thread Armour Plating. For material with low shear strenght eg. aluminum-alloys and magnesium alloys. Used in machine-building, electrical, automotive, medical and aerospace industries.
Thread Repair of damaged or worn-out threads.
