ABSTRACT:
In an apparatus in which workpieces are joined by self-piercing rivets, for example, a jig is used to determine whether axial alignment of a punch and a die is within an acceptable range. The jig substitutes for a die and has a shank and a head, the shank fitting within a die-receiving bore of the apparatus and the head having an axial opening receiving the punch when alignment is within the acceptable range. The head is constructed to permit viewing of the relationship of the punch and the opening.
