ABSTRACT:
A J-nut, which is a clip having a crown on one side, is inserted into a hole in a portion of an element in a single plane so that portions of the clip are on opposite sides of the portion having the hole with the J-nut having its crown, which may have a greater thickness than the remainder, either above or below the remainder of the J-nut. The J-nut is inserted by a tool having a locator disposed within the hole after the J-nut has been advanced to a position in the tool in which a portion of the J-nut is positioned within a passage within the locator. When the crown is on the bottom of the J-nut, the crown rests within this locator passage. The J-nut is oriented with the crown either up or down even though all the J-nuts are fed from a feeder in the same orientation. The locator is not positioned in the hole in the element until the J-nut is positioned with a portion within the locator passage. The tool also has a flat surface to rest on the portion of the element having the hole to further aid in orienting the tool. The J-nut is advanced into the hole by rotation of discs engaging a portion of the J-nut. The tool also may insert a J-nut over an edge of an element at a predetermined position.
