Abstract: A fastening apparatus includes a reducer bolt and a complimentary female threaded element. The reducer bolt has an elongate threaded shank for inserting into the complementary female threaded element. The reducer bolt has a collar defining a threaded female opening. The collar is carried concentrically on the shank and has a diameter greater than the shank so that the collar contacts the complementary female threaded element to prevent further insertion of the shank into the female threaded element. A head is carried concentrically on the collar, and has an aperture communicating with the collar opening to receive a complementary male threaded member which mates with the threaded female opening of the collar. The head includes an engagement mechanism for receiving a complementary tool, such as a wrench, so that engagement between the shank and the complementary female threaded element is adjustable by turning the head with the tool.

Abstract: A knockdown furniture assembly includes a frame releasably connected to two arm pieces. Each arm piece has a bottom rail having two carriage bolts extending outward therefrom for positioning in the frame. The bolts are held in place on the arm pieces and the frame by washer and nut assemblies. The washer and nut assemblies are countersunk in the rails to allow for a flush connection between the rails and the frame. The arm pieces can be easily disassembled from the frame by disengaging the washer and nut assemblies and removing the frame from off of the bolts.
