Abstract
A system for indicating a depth of engagement of two threadably engaged surfaces of a support pedestal. The system includes at least a first thread protuberance disposed on a first threaded surface of the support pedestal and at least a second thread protuberance disposed on a second threaded surface of the support pedestal. The first thread protuberance impinges against the second thread protuberance when the first and second threaded surfaces are threadably engaged and rotated to provide sensory indication of a depth of engagement of the first and second threaded surfaces.
