Pre-wind Threaded Mandrel (Economy)
A threaded mandrel within a slim tool body that has a pre-wind nozzle.
The pre-wind nozzle is necessary for the installation of screw locking wire thread inserts where the insert must be compressed (pre-wound) prior to installation in the tapped hole.
Suitable for both free running and screw locking inserts
Method of use:
- Withdraw the threaded mandrel from the main tool body
- with a window style tool the mandrel will only need to be withdrawn to the top edge of the window
- with a full body tool the mandrel will be withdrawn completely
- Wind the insert onto the threaded portion of the mandrel ensuring that the driving tang is fully engaged with the abutment (raised edge) of the tool
- Move the threaded mandrel with the engaged insert towards the nozzle
- Wind the insert clockwise into the nozzle, until it meets the nozzle opening
- Place the tool squarely over the tapped hole
- Continue winding until the insert is positioned approximately 1/4-1/2 turn below the surface of the tapped hole
- Unwind the threaded mandrel.
