In various examples, a set screw apparatus includes a set screw including a set screw body. An abutment extends radially outwardly from the set screw body and longitudinally separated from a threaded set screw area of a first length by an unthreaded set screw area of a second length of the set screw body. A block includes a bore. A threaded block area includes a third length, wherein the abutment inhibits movement of the set screw past the threaded block area and removal of the set screw from the bore. The third length is shorter than the second length so that an entirety of the threaded block area can be disposed within the unthreaded set screw area, such that the set screw is freely rotatable within the bore, but retained within the bore, if turned in a first direction with respect to the block. |

1. A set screw apparatus comprising:
a set screw including:
a set screw body including a first screw end and a second screw end;one or more set screw threads extending radially outwardly from the set screw body and disposed along a threaded set screw area of the set screw body, the threaded set screw area extending from the first screw end toward the second screw end and including a first length measured longitudinally along the set screw body; andan abutment extending radially outwardly from the set screw body proximate the second screw end and longitudinally separated from the threaded set screw area by an unthreaded set screw area of the set screw body, the unthreaded set screw area including a second length measured longitudinally along the set screw body; and a block including:
a bore sized and shaped to accept the set screw within the bore for threadably engaging the set screw within the bore, the first screw end being configured to fit within and pass through an opening of the bore in order to insert the set screw into the bore; andone or more block threads extending radially inwardly from the bore and disposed along a threaded block area of the bore, the one or more block threads being complementary with the one or more set screw threads so as to be threadably engageable with the one or more set screw threads, the threaded block area including a third length measured longitudinally along the bore, wherein the abutment of the set screw is sized and shaped to abut, but not threadably engage with, the one or more block threads to inhibit movement of the set screw and outwardly past the threaded block area away from the opening of the bore to thereby inhibit removal of the set screw from the bore, the third length being shorter than the second length so that an entirety of the threaded block area can be disposed within the unthreaded set screw area between the threaded set screw area and the abutment, such that, with the threaded block area disposed within the unthreaded set screw area:
if turned in a first direction with respect to the block, the set screw is freely rotatable within the bore, but retained within the bore as the abutment of the set screw abuts the one or more block threads; andif turned in a second direction, opposite the first direction, with respect to the block, the one or more set screw threads are threadably engageable with the one or more block threads to move the set screw in an inward direction toward the opening of the bore. |
