Abstract: A hole punch assembly for punching holes in papers and such, usually having dual spring-loaded punch units attached to a base member. The punch assembly is constructed from formed sheet steel and includes a rectangular-shaped base member having two spaced-apart rectangular shaped depressions and openings therein, each for receiving a spring-loaded punch unit rigidly attached to the base. The punch unit includes a frame folded to provide a gap through which a punch rod is extended through a hole, the frame enclosing a compression spring located around the punch rod and a spring-retaining shoulder ring is provided in a groove located between the frame and the upper end of the compression spring. The punch unit is rigidly attached to the base member so that the gap has its lower surface flush with the upper surface of the base member, to allow paper stacks or paper sheets for punching to be guided into the gap without any obstructions or hang-up.
