Abstract
A low profile and removable set screw for use in connecting one medical implant to another and for similar uses. The set screw has a base and a head that is breakable from the base in a breakaway region at a preselected torque, such that the head allows rotation of the screw and torquing of a tip of the base against one of the implants during installation. The screw includes a region of comparatively smaller cross-sectional area that defines and creates the breakaway region to trigger breaking. The screw also includes a pair of slots extending radially from an outer threaded surface of the base part way into the base. The slots intersect with the breakaway region, but not with each other leaving a center core in the base. A tool is provided for removing the base after the head is broken away. The tool includes a pair of spaced ears that are received in the slots and provide for rotation of the base by rotating the tool. A bore radially extends part way inward from the base so as to be centered on the breakaway region and partially overlapping a respective slot.
