    Determine if lead nuts, screw collars, and other parts with internal Acme threads are within tolerance. These gauges are attached to a handle to help you quickly thread or unthread them. All are precisely manufactured to tight tolerances. Instead of replacing the whole tool when a gauge wears down, you can insert a new gauge (not included) into the handle.
    A part is within tolerance if it’s easy to thread the go gauge into the part but difficult to thread the no-go gauge more than two turns.
    Go Gauges—Go gauges check the minimum hole diameter.
    No-Go Gauges—No-go gauges check the maximum hole diameter.
    For Thread Fit—Thread fit designates the tightness or looseness of mating threads. Acme Class 2G is standard for Acme threads.
