Hanger bolt is a two-way threaded fastener mainly used for furniture assembly.
Made of Grade 4.8 carbon steel with blue white zinc coating, it avoids rust when used indoors. It carries two different threads on each end. The wood tapping thread with sharp tip can screw into solid wood without pre-drilling holes. The machine thread matches metal nuts and furniture legs to form steady joints.
A flat hex grip sits between the two threads. Workers can clamp this area with regular wrenches to spin the bolt smoothly and stop sliding during installation. Thick thread teeth lock into wood fiber to keep joints tight for long-time use.
It differs from full double wood thread studs as it connects wood and metal parts, hiding entirely inside workpieces without protruding heads to keep furniture surface neat. All goods pass torsion and pull tests before shipment, meeting standard furniture hardware requirements. Buyers can order custom lengths and surface finishes for bulk production.
