A releasable adaptor is carried on the end of the pick-and-place vacuum nozzle which diffuses and restricts the air flow access of the nozzle to the top surface of an apertured fastener such as a nut while covering the fastener hole. The adaptor allows a standard nozzle to develop sufficient suction to lift the nut/adaptor combination and transport it to its desired target location such as a circuit board. There, the nut is released from the adaptor, which is then lifted by the nozzle and transported back to the supply location. This functionality is achieved by a unique adaptor air valve which the PNP equipment operates both mechanically and through its controlled application of negative air pressure applied to the adaptor by the nozzle.
