Finishing article having an integral mounting hub and improved base

A finishing article having a disposable drive member non-removably affixed thereto for mounting on a threaded rotatable spindle for use with a power tool comprising:

• a finishing article having a face and a back and having a first centrally disposed aperture therethrough;
• a backing member having an inner and outer surface and a diameter smaller than the diameter of said finishing article and defining a second centrally disposed aperture therethrough, said backing member inner surface seated on said back of said finishing article with said first and second apertures aligned;
• a retaining nut having a hollow internally threaded body having first and second ends and a first radially outwardly extending flange extending from said first end of said body, said body extending through said first and second apertures of said finishing article with said radial flange seated against said face;
• means protruding outwardly from said second end of said body to non-removably secure said retaining nut and said backing member together on said finishing article without the use of adhesives and allowing relative axial movement between said retaining nub and said backing member;
• and
• adapter means for applying force to said finishing article when said finishing article is threadably affixed to and seated on said spindle, whereby relative axial movement between said retaining nut and adapter means toward each other is permitted to thereby increasingly compress said finishing article as operative loads are applied to said finishing article during use on said power tool, said adapter means including an inverted generally cup shaped metallic member and a molded plastic bearing member, said bearing member being sandwiched between said metal cup and said backing member.
