Automotive frame assembly

A method for manufacturing an automotive frame assembly, comprising:

• providing an inner rail;
• providing an opposing inner rail;
• providing a cross member having a first end and a second end;
• simultaneously accessing an exterior side and an interior side of at least one of said inner rail and said opposing inner rail;
• fastening said first end of said cross member to said inner rail;
• fastening said second end of said cross member to said opposing inner rail;
• providing an outer rail;
• providing an opposing outer rail;
• fastening said outer rail to said inner rail;
• and
• fastening said opposing outer rail to said opposing inner rail.

An automotive frame assembly comprising:

• an inner rail having an interior side and an exterior side;
• a cross member having a first end and a second end, said first end being fixedly coupled to said exterior side of said inner rail;
• an opposing inner rail having an opposing exterior side and an opposing interior side, said opposing exterior side being fixedly coupled to said second end of said cross member;
• an outer rail being fixedly coupled to said interior side of said inner rail;
• and
• an opposing outer rail being fixedly coupled to said opposing interior side of said opposing inner rail;
• wherein said exterior side and said interior side of said inner rail are simultaneously accessible to a fastener applicator when said outer rail and said first end of said cross member are coupled to said inner rail;
• wherein said opposing exterior side and said opposing interior side of said opposing Inner rail are simultaneously accessible to a fastener applicator when said opposing outer rail and said second end of said cross member are coupled to said opposing inner rail;
• wherein at least one two-sided fastener is operatively applied to said exterior side and said interior side of said inner rail so as to fixedly couple thereto at least one of said first end of said cross member and said outer rail.
