Anti-cross threading device |
摘要 |
The present invention permits a screw or male member to align prior to entering a threaded section and being driven. This alignment can avoid cross threading of the screw and the internal threads as often happens with power driven screws. The present invention generally includes a device with an unthreaded section and a threaded section. A screw or male member passes through the unthreaded section prior to entering the threaded section and causes the screw or male member to be aligned before being driven.
