ABSTRACT:
A device is disclosed for setting and securing a threaded member that is to be fixed with casting material in a recess or hole in laminar composite board-like members, such as those of honeycomb construction. The threaded member is of the type having a flange-like head to be located closely adjacent the plane of the outer skin of the composite material, and having a female threaded body extending into the recess with clearance, such that casting material injected into the clearance around the body will harden to secure the threaded member in the recess. The flange-like head has charging and venting openings for the injection. The setting device comprises a plate-like body formed with corresponding charging and venting openings, but of larger diameter than the recess opening, such that the device can be intimately applied with its underside against the flange-like head of the threaded member. A cylindrical projection from the center of the underside of the plate-like body extends into the threaded bore of the threaded member, where it is detachably held by friction. The plate-like body has an upstanding collar on its upper side that surrounds the charging and venting openings to catch any overflow of casting material, and the collar is formed with flattened portions for application of a wrench, such that after hardening of the casting material, the setting device is rotatable by a wrench to shear the casting material between the setting device and the threaded member, after which the setting device is removed.
