    • A fastener (10) includes a sleeve (14), a core bolt (12), and an insert (16). The sleeve (14) includes a first portion (72) having a first inner diameter (78), a second portion (74) having a second inner diameter (80), and a step (82) intermediate the first (72) and second (74) portions. The core bolt (12) includes a cylindrical portion (30) having an outer diameter (48), a threaded portion (44) having a major diameter (52), and a thread run-out (46) intermediate the cylindrical (30) and threaded (44) portions. The insert (16) is disposed within the sleeve (14) and is sized and shaped to abut and be retained between the step (82) of the sleeve (14) and the thread run-out (46) of the core bolt (12) when the fastener (10) is in a pre-installation position. The fastener (10) compresses the insert (16) between the step (82) of the sleeve (14) and the thread runout (46) of the core bolt (12) by an installation motion of the core bolt (12). The insert (16) is adapted to deform away from the core bolt (12) to initiate formation of a bulb (102) in response to the compression.

    • A fastener installation tool (10) including a cylinder assembly (12) having a housing (18) and a handle/sleeve assembly attached to the housing (18). The handle/sleeve assembly includes a handle (14) having a bore (58) and an inner wall (60) defined by the bore (58). The handle/sleeve assembly further includes an outer sleeve (100) having an outer wall (102) and an inner wall, and an inner sleeve (102) having an outer wall and an inner wall. The outer sleeve (100) is positioned within the bore (58) of the handle (14), while the inner sleeve (102) is positioned concentrically within the outer sleeve (100) to form an annular space (104) between the outer wall of the inner sleeve (102) and the inner wall of the outer sleeve (100). The annular space (104) is utilized to conduct hydraulic fluid.
