Abstract
A ratcheting fastener system such as for point of purchase displays. A bolt has a shank with a head end and a distal end, and a plurality of bolt threads on the shank, each thread having a thread start at the distal end. A nut has a bore with a plurality of thread segments in the bore adapted for engaging the bolt threads when axial force is applied to the bolt with the distal end inserted in the nut. Deflection of the nut thread segments occurs in controlled locations. The bolt and nut can be formed as a single unit connected by a frangible link.
