About Insert Nuts

For Wood An insert nut, or knock in nut, provides a strong, permanent threaded socket for a wooden work piece, similar to a wall anchor. The Insert Nuts ensures strong resistance against pull-out due to torsion or vibration, providing a concealed internal fixing where there is no access to the nut after the bolt is inserted. Insert nuts are inserted into a pre-drilled hole by one of two means: screw in Insert Nuts and hammer in Insert Nuts. Screw-in insert nuts have an external thread and hex head and are screwed in with an Allen wrench. Hammer-in insert nuts are lined with barbes and are hammered in. In both cases, the external protrusions bite into the wood, preventing the nut from either turning or pulling out. Insert nuts should not be confused with barrel nuts or T-nuts, which require that the working piece be drilled through and are fastened behind the work piece. Insert Nuts can be used in conjunction with 'Joint Connector Bolts' to create a firm & secure furniture assembly fixing.
