Loose or Non-Interference Fit
The holes are prepared slightly larger than the shank of the pins.The pins are loose in the holes and need something to hold them from rotating while the fasteners are installed.
The pins have a female hex on the threaded end. We have a hex key system that places a hex key (like a allen wrench) through the socket and into the hex of the pin. This hex key is attached to the tool with a spring and is used to keep the pin from rotating while the collar or nut is installed.
ORDER TOOL WITH A HEX KEY SET-UP
The holes are prepared slightly smaller than the shank of the pins. The pins are forced into the holes and are held in place by this tight fit. The pins will not rotate when nuts are tightened on them.
TO ORDER A TOOL WITHOUT HEX KEY SET-UP ADD "U" AFTER TOOL ORDER NUMBER
"U" after the tool order number removes the threaded shaft that holds the hex key spring.
