摘要： An offset nose assembly (10) for installing fasteners is provided that generally includes a drawbar (16), a swage anvil (12) and a collet (14). The drawbar (16) has three portions with the third portion transitioning from the second portion by a chamfer (56), the chamfer (56) being of a preselected angle that is adapted to positively engage a chamfer (58) of a preselected angle of a piston (50) of a fastener installation tool (30). Additionally, a generally L-shaped guard assembly (70) is provided that is disposed on the collet (14) to cover a gap (66) defined between the collet (14) and the swage anvil (12). Also, a deflector (38) is provided that is attached to a nut (36) that is threadedly engaged with the rearward end of a bore in the collet (14), the deflector (38) having a section of a uniform constant outside diameter that integrally transitions to a section that has an outside diameter that gradually lessens along its length.
