Circuit interupter with screw retainment

A circuit interrupter comprising:

• separable main contacts;
• an operating mechanism interconnected with said separable main contacts;
• a housing in which said separable main contacts and said operating mechanism are disposed, said housing including a first housing member having a channel with an opening, said opening formed within a first recessed region of said first housing member, said first recessed region formed within a second recessed region of said first housing member, said housing further including a second housing member having a first opening;
• a retaining device having a second opening;
• a screw having a head portion and an end portion opposite said head portion, said end portion inserted into said first opening and into said second opening whereby said retaining device is positioned between said end portion and said second housing member, and said second housing member is positioned between said retaining device and said head portion, said end portion insertable into said channel such that said retaining device is positioned within said second recessed region and adjacent said second housing member;
• wherein said first and second recessed regions are sized to prevent threading action between said first housing member and said screw within said first and second recessed regions, and said first opening is sized to prevent threading action between said second housing member and said screw;
• and
• wherein said second opening is sized to provide threading action between said retaining device and said screw, and said channel is sized to provide threading action between said first housing member and said screw within said channel.
