Abstract
A post construction comprises a post body having an externally threaded stud embedded therein and projecting axially from one end thereof for threaded engagement with the playfield board of a pinball game. A hex surface on the post body facilitates driving the stud into the playfield board. In one embodiment an annular guard flange protects the playfield board during the mounting operation and in another the hex surface is offset a slight distance from the post body end to prevent engagement with the playfield board. In one embodiment an annular recess is provided in the post body around the stud to accommodate whiskers of playfield board material ejected during the threaded mounting to accommodate flush seating on the playfield board. Two circumferential grooves in the outer surface of the post body respectively receive rubber bands for interconnecting a plurality of the post constructions, the grooves being so positioned that the two bands are spaced apart a distance less than the diameters thereof.
