Claim 0:
1. A fastener, comprising:
a bolt having a head at a proximal end and a cylindrical shaft extending from the head to a distal end along a central longitudinal axis; the head having a diameter larger than the shaft;
the bolt including toothed segments; each toothed segment having a tooth around the shaft and along the longitudinal axis; each toothed segment including individual teeth all having a load-bearing surface facing the proximal end;
the bolt including a plurality of blank segments without teeth interspersed between toothed segments around the shaft and along the longitudinal axis; and
a nut defining a cylindrical bore extending through the nut along the longitudinal axis from a proximal end to a distal end of the nut; the bore having a bore surface;
the bore being sized and configured to receive the shaft of the bolt inside the bore;
the nut including a plurality of teeth on the bore surface; each tooth on the nut having a load-bearing surface facing the distal end and sized and configured to abut against the load-bearing surfaces of the teeth on the shaft to prevent translation of the nut in the distal direction and allow translation of the nut in the proximal direction toward the head.
