  • Apparatus and methods for measuring thread depth on a threaded member
    Patent number: 11118888
    Abstract: A tool for evaluating a thread depth includes a frame having an elongate portion extending in a first direction; a first contact member coupled to the frame and reciprocable in a second direction between a baseline height and a retracted height, the baseline height being greater than the retracted height. An output device provides an output in response to the height of the first contact member. A reference member is coupled to the frame at a first distance D1 from the first contact member as measured in the first direction; and a second contact member coupled to the frame is disposed at a second distance D2 from the first contact member as measured in the first direction, such that D1 is greater than D2.
