摘要： Disclosed is a blind fastener (10, 110, 210, 310, 410) including a core bolt (50, 150, 250, 350, 450), a body (20, 120, 220, 320, 420) and a blind side clamp (40, 140, 240, 340, 440) on the core bolt insertable through an aperture, where moving the core bolt relative to the body forms an enlarged bearing surface against a back surface. The fastener includes an extension (28, 128, 228, 328, 428) from the body with a wrenching surface (31, 131, 231, 331, 431) and an undercut (32, 132, 232, 332, 432) between the body and the wrenching surface that is optionally configured to break when torque equal to the sum of an application specified minimum installed seated torque and a manufacturing failure torque tolerance for the undercut is applied. Also disclosed is a method of dressing the installed fastener including machining through the top surface of the fastener along a longitudinal axis (A) of the core bolt of the fastener and the extension that extends from a body of the fastener until intersecting the undercut between the extension to remove the extension.

摘要： A fastener for clamping work pieces together through aligned apertures comprises a core bolt (50; 150; 350) comprising a bolt head (55; 155; 355), a first externally threaded portion (51; 151; 351) and an unthreaded shank portion (52; 152; 352); a body (20; 120; 220; 320) positioned on the core bolt and a deformable sleeve (40) positioned on the core bolt between the bolt head and the body. The body comprises an enlarged head (21; 121; 221; 321), a first internally threaded portion (25; 125; 225; 325) and a smooth wall through bore portion (24; 124; 224; 324) positioned proximate to the enlarged head. An outer diameter of the unthreaded shank portion (52; 152; 352) of the core bolt is approximately equal to an inner diameter of the smooth wall through bore portion (24; 124; 224; 324) permitting a close fit of the unthreaded shank portion in the smooth wall through bore portion.

摘要： Disclosed is a blind fastener that includes a body, a bolt and a sleeve that has an internal recess that contains an insert. The body includes a tapered ramp that the sleeve is enlarged over. Compression of the sleeve against the work piece causes the sleeve to fold at the internal recess to form an enlarged blind side head that bears against the work piece.

摘要： A lockbolt (100, 200) which includes a head portion (102) and a shaft (104) which extends from the head portion (102). The shaft (104) includes at least a portion which is threaded and has a multi-lobular profile. A collar (120) is swageable onto the multi-lobular threaded portion (104), and thereafter the lobes (114) provide that the collar (120) does not tend to vibrate loose from the threading. The fact that the section which has a multi-lobular profile is also threaded provides that the collar (120) (or a conventional threaded nut) can be selectively rotatably removed and re-installed on the lockbolt (100, 200). Before swaging, the collar (120) may initially include a cylindrical bore (130), or a bore (130) which is multi-faceted, preferably generally corresponding to the profile of the multi-lobular portion of the lockbolt (100, 200). The lockbolt (100, 200) may also include a frangible pintail (106, 202), wherein the multi-lobular threaded portion is disposed between the head portion of the bolt and the frangible pintail.

摘要： A blind fastener with an improved drive nut and assembly process. The blind fastener includes a screw (20), a sleeve (30), a nut (40), and a drive nut (50). The drive nut (50) has a smooth bore and protruding nibs (56) that mate precisely with a driving recess located in the nut head (44). A retaining device is used to retain the drive nut (50) on the screw (20) against the nut (40). Once the new assembly process for the blind fastener has been completed, the drive nut (50) will have been mated with the nut head (44) to prevent any rotation of the nut (40) during installation of the blind fastener. The assembly process will now include placing the sleeve (30) over the threads (22) of the screw (20) to a position adjacent the screw head. The nut (40) is then threaded onto the screw (20) adjacent the sleeve (30). The drive nut's protruding nibs (56) are next aligned and physically engaged into the driving recess (46) of the nut head (44) by sliding the smooth bore over the screw (20). A retaining device is placed over the screw adjacent the drive nut to retain the drive nut (50) to the screw (20). The retaining device can be an adhesive.

摘要： This invention relates to an improved blind fastener assembly (18) and an improved joint assembly using the blind fastener assembly. The blind fastener assembly (18) is adapted to be installed in a workpiece (10) having a first and a second surface (11,12) with an opening (13) therebetween. The blind fastener (18) is of the type having a core pin (19), expander means (20), expandable sleeve means (21), and resilient washer means (22), each having an initial diameter which permits it to pass through the opening (13) in the workpiece (10). The improvement in the blind fastener assembly (18) in accordance with this invention comprises the washer means (22) having two portions including an inner portion (38) and an integrally formed outer flange portion (39). The inner portion (38) has a tapered nose section (40) tapering outwardly away from the core pin shank portion to facilitate expansion of the sleeve means (21) over the inner portion. The integrally formed outer flange portion (39) is adapted to be unfolded by the sleeve means (21) to form a bearing surface against the second surface (12), of the workpiece (10). Advantageously, the washer means inner portion (38) is thick-walled and the outer flange portion (39) is thin-walled. Furthermore, the washer means (22) outer flange portion (39) has a wall thickness of generally from about 0.2 to about 0.5 times the combined wall thicknesses of the washer means (22) inner portion (38) and outer flange portion (39). The washer means (22) can also have a leading internal surface inclined outwardly to facilitate the expansion of the washer means (22) over the expander means (20) tapered nose portion (30).

摘要： This invention relates to a fastener (10) of a type having a core pin (11) including a threaded shank portion (15), an enlarged head (16) at one end thereof, and a torque tool engaging means (17) on the opposite side of the core pin from the head. The fastener (10) further has an expander means (12) including the head (19) with at least one recess (20) in the outer surface at one end thereof and a tapered nose portion (22) at the other end thereof. The expander means (12) has a bore (24) therethrough to receive the threaded shank portion (15) of the core pin (11). Also, the fastener (10) has sleeve means (13) on the core pin (11) between the nose portion (22) of the expander means (12) and the enlarged head (16) of the core pin (11). An internally threaded drive nut (14) is threadedly mounted on the core pin (11). The drive nut (14) has a bearing surface (27) facing towards the outer surface (21) of the head (19) of the expander means (12). The improvement in the fastener (10) in accordance with this invention comprises the drive nut's bearing surface (27) having at least one projecting portion (28) adapted to engage in the recess (20) in the outer surface (21) of the head (19) of the expander means (12) without deformation of the projecting portion (28). The number of projecting portions (28) can be equal to or less than the number of recesses (20).
