Abstract
Abstract A multitude of elongated fasteners are removably held in a uniform array in an assembly comprising a holding panel and at least one air-impermeable compartment associated with each fastener and disposed below the holding panel. The compartment contains a liquid bonding agent which is in contact with the shaft of the fastener. When the fastener is removed from the holding panel and utilized, the holding agent functions as a lubricant which subsequently hardens to lock the fastener in place. The bonding agent may be a two-component composition. The uniformity of the array facilitates robotics handling.

Claim 1
Independent Claim
139 words
An assembly of self-locking fasteners comprising: (a) a semi-rigid holding panel having upper and lower flat surfaces, (b) a multitude of elongated fasteners, each having a shaft portion terminating in head and bottom extremities, said fasteners being removably held by said panel in a manner such that the long axis of each fastener is perpendicular to the panel and the head extremity is above said upper flat surface, said fasteners being uniformly spaced apart in an array having straight lines, and (c) at least one air-impermeable compartment associated with each fastener below said lower flat surface and containing a liquid bonding agent having a viscosity within the range of about 4 poises and 80 poises, measured at 25 degrees C., and capable of curing to solid form, the shaft portion of said fastener being immersed in said bonding agent.
