Installation Sequence
Step 1. The pin is inserted through a prepared hole and the collar is placed over the pintail.
Step 2. The nose assembly, attached to HUCK's installation tool, is placed over the pintail. The nose assembly pulls on the pintail, drawing the work pieces together.
Step 3. Continued pulling on the pintail moves the anvil forward swaging the collar into the locking grooves. The controlled swaging lengthens the collar to develop clamp.
Step 4. When the swaging is completed, the pintail separates from the pin, and the tool ejects the swaged collar out of the anvil, completing the installation.
