摘要： A mechanically locking fastener has external threads for installation in the threaded bore of a workpiece. A lock ring has internal radial serrations locked in serrations of the fastener proper, and external radial teeth of a form for gripping the wall of the workpiece bore when turning moments tend to loosen the fastener and to pass over the bore wall upon rotation in the opposite direction. The lock ring has a slip plane to permit contraction of the ring to a diameter no greater than the major diameter of the fastener and expansion of the ring when the fastener undergoes moments tending to loosen it. The fastener proper may be a stud or an insert. An external chamfer of the ring bears against a cooperating internal surface of the workpiece to positively determine the axial location of the insert with respect to the workpiece.

摘要： A blind fastener system comprising a ductile sleeve having an expansion portion of small inner diameter in a thin workpiece and having a bulbing portion of larger inner diameter extending on the blind side of the workpiece, and a threaded expander member having an expander portion for expanding the sleeve expansion portion and a head portion for bulbously deforming the sleeve bulbing portion, both actions occurring on axially pulling the expander member. The expander portion has a tapered, radiused leading end followed by a configured (splined, knurled, etc.) portion for the remainder of the active length. The protrusions of the configured portion leave a void volume between them and between the minor and major diameters of the protrusions, and the volume of the sleeve expansion portion between the small inner diameter and the projection of the large inner diameter is approximately 0.5 to 0.8 of the void volume of the configured portion. The protrusions have blunt outer surfaces. The expander member may be a nut, in which case the minor diameter of the protrusion is at least 1.23 times the major diameter of the internal threads of the expander member, which threads are inwardly of at least a portion of said protrusions. The length of the bulbing portion is approximately one-half the outer diameter thereof, while the large inner diameter is approximately nine-tenths of the outer diameter of the sleeve bulbing portion. The axial length of the sleeve expansion portion is at least equal to the thickness of the workpiece, and the expansion section of the expander member is at least equal to the axial length of the expansion portion of the sleeve.The expander member may have internal threads, to serve as a nut, or may have a stem with external threads, to serve as a bolt or stud. The stud may receive an electrical connector, the fastener system being of suitable electrically conductive materials.
