ABSTRACT:
An improved, elongated threaded fastener is disclosed having a first portion with first threads and an adjacent second portion having second threads. The diameter of the second portion is greater than the diameter of the second portion, while the pitch of the threads on the second portion is less than the pitch of the threads on the first portion. The second portion is also formed with a driver engaging surface to engage a driving tool to apply a rotative force to the threaded fastener. A nut is threaded onto the second end portion to enable the threaded fastener to be utilized for nut packing or micro-adjustment.
