Extreme offset nose assembly

An apparatus for installing fasteners comprising:

• a drawbar having a first diameter portion, a second diameter portion, a third diameter portion, and threads disposed at a rearward end of the drawbar,
• the first diameter portion having an enlarged bearing head and a diameter greater than the second diameter portion,
• the second diameter portion having a diameter at least equal to the third diameter portion and transitioning from the first diameter portion by a shoulder,
• the third diameter portion transitioning from the second diameter portion by a shoulder,
• the shoulder having no contact with an end of a piston of a fastener installation tool;
• an anvil having a cavity, a first aperture, and a second aperture,
• the first aperture being adapted to receive a portion of the first diameter portion of the drawbar;
• a collet having a first bore and a second bore,
• the first bore being adapted to receive a chuck jaw assembly for grippingly engaging fasteners,
• the second bore being adapted to receive the second diameter portion of the drawbar,
• the collet being slidably disposed within the anvil;
• and
• the drawbar having a section of the first diameter portion disposed within the first aperture,
• a front section of the second diameter portion threadedly engaged within the second bore of the collet,
• a rearward section of the second diameter portion passing through the second aperture of the anvil thereby providing a bearing surface between the rearward section of the second diameter portion and the second aperture of the anvil, and
• the third diameter portion passing through the second aperture of the anvil.
