Claim:
1. A machine for applying a coating product to screws, particularly the threaded shaft of a screw, with a coating product, comprising: a support frame that defines an operating space through which screws are advanced, said operating space having an inlet end and an outlet end that define a path of travel of said screws through said operating space; a feed ramp unit for feeding said screws into said operating space, said feed ramp unit being located at said one inlet end upstream from said operating space, as viewed in a forward direction of travel of said screws, along said preset path of travel, said feed ramp unit having support points defined therein for supporting said screws with the shaft extending in a first direction perpendicular to said path of travel and lying on a horizontal plane; dispensing/spreading means supported in said operating space and extending along said preset path of travel between said one inlet end and said one outlet end, for applying a coating product to the shafts of the screws traveling through said operating space; advancing means supported in said operating space and operating along said preset path of travel between said one inlet end and said one outlet end, for driving the screws in said operating space; abutment means supported in said operating space for defining an abutment and positioning plane for said screws along said path of travel as said screws are advanced from said one inlet end to said one outlet end, a head abutment unit comprising an abutment wall extending parallel to said bearing blade and said stationary portion of said feed ramp unit, substantially along their entire longitudinal dimension, to define an abutment and guide surface for the head surfaces of said screws,
