[Conclusion process]
1. Insert a bolt into the hole and screw the collar to the pin.
* The screws are not for tightening. For temporary fixing.
2. Start by putting the tool on the parallel threaded pin tail. As the puller pulls the bolt into the tool, it simultaneously pushes the collar and eliminates the part gap.
3. The anvil starts swaging by starting to pull at the specified strength. While the collar bites into the thread, it extends the collar forward to obtain the required axial force.
4. When the swage is complete, release the switch and the anvil will return to the rear, releasing the pintail from the puller.

* Stainless steel and aluminum C50L bolts are made to order.
[C50L color dimension] unit = mm
Note 1: When selecting a flanged collar, specify the grip number by adding the J dimension to the material thickness dimension of the material to be fastened.
Note 2: Half color is made to order. The tensile and axial force values will be lower than specified. Please contact us for details.
When selecting a half collar, subtract the J dimension in the material thickness dimension of the material to be fastened and specify the grip number.
Note 3: The 5/8 "(20) diameter H dimension is 19.55-20.45 mm when the collar material is aluminum or SUS.
