The antiluce drop lock pin is part of the family of anti loosening fasteners, but its locking mechanism is different from the others. It's been used to secure locks in place in systems like the Indian railway system or construction heavy equipment in Brazil. It drops into a pre bored hole which assists in locking (cam action locking). This ensures that the pin will not budge – will not loosen – even during harsh environments like continuous vibration or shock loading. The design allows the pin to be threaded off and on, which simplifies maintenance and servicing tasks. Its ease of teaching to workers of different cultures has enabled its use in many different industries.
