Method, system, and apparatus for boney structure tap

A dense tissue tap apparatus for creating a threaded tap of a first diameter within a dense tissue to a known depth, comprising:

• an elongated shift including a proximal end, a distal end, and a longitudinal axis between the ends, the shaft including a non-tapping section at the proximal end and a tapping section at the distal end, the tapping section including:
• a continuous tapping section extending from a distal most end and having a first length and including a tapping thread having a first maximum outer diameter that may create a threaded tap of the first diameter in dense tissue;
• and
• a first reduced diameter section immediately and proximately adjacent the continuous tapping section, the first reduced diameter section having a second length and a second maximum outer diameter less than the first maximum outer diameter;
• a first marker section immediately and proximately adjacent the first reduced diameter section, the first marker section having a third length and a maximum outer diameter about equal to the first maximum outer diameter;
• a second reduced diameter section immediately and proximately adjacent the first marker section, the second reduced diameter section having the second length and the second maximum outer diameter;
• a second marker section immediately and proximately adjacent the second reduced diameter section, the second marker section having the third length and a maximum outer diameter about equal to the first maximum outer diameter;
• and
• a third reduced diameter section immediately and proximately adjacent the second marker section, the third reduced diameter section having a fourth length and the second maximum outer diameter, the fourth length less than or equal to the second length,
• wherein the third length is less than half the first length, and wherein the first marker section and the second marker section include a tapping thread similar to the continuous tapping section tapping thread.
