Abstract
A fastening assembly includes: PA1 (a) an axially elongated fastener having axially spaced differentially threaded portions respectively adapted to threadably engage threaded extents on members to be interconnected, and PA1 (b) structure extending at the side of the fastener and having interconnection therewith characterized as facilitating transmission of torque to the fastener to rotate the fastener about the axis while allowing relative axial displacement between the fastener and the structure, whereby the threaded portions are then adapted to threadably interfit the threaded extents to make-up the assembly.
