The Monadlock panel fastener incorporates the beam lock design for superior vibration resistance. This feature also extends the locking capability up to 1,500 seated cycles. Multiple lead thread configurations are available to facilitate quick operation. thanks to its unique design, this fastener can accommodate a large variation in grip. Nut plates allow for radial float making it easier to assemble on curved panels, or panels with hole misalignments.

Stud bolt configurations are held in the panel by a retaining ring. With the hold-out type, the stud bolt, when disengaged from the nut plate, can be pulled out to hold-out position to facilitate easy removal of curved or hinged panels.
