Paragraph Number

158

In one embodiment, the shaft 1002 engages the bone fastener by way of threads 1014 that engage internal threads 1022 of a socket 1030 of the inserter 1008 which is secured to the bone fastener. In the illustrated embodiment, rotation of the shaft 1002 in a first direction may cause the threads 1014 to advance within the internal threads 1022 of the socket 1030 and thereby draw the protrusion 1006 closer to the collar 1004. As the threads 1014 advance, the protrusion 1006 presses against at least a portion of the collar 1004 (e.g., the inferior surface 1024 may press against the superior surface 1026). In certain embodiments, this pressure (or bias) is sufficient to retain the collar 1004 and a coupled guide in a first orientation about an engagement axis.
