Double threaded hanger bolts are versatile fasteners with two distinct threaded ends, typically a lag screw thread at one end and a machine screw thread at the other. This design allows them to be securely installed into wood or other soft materials while providing a machine screw thread for attaching nuts, washers, or other components.

Definition

Double threaded hanger bolts are specialized fasteners featuring a lag screw thread on one end, designed for insertion into wood or similar substrates, and a machine screw thread on the opposing end, compatible with standard nuts and machine-threaded components. This unique construction enables a secure, concealed connection in one material with a protruding threaded stud for external attachments.

Advantages

• Versatile Fastening: The dual-thread design allows for secure embedding into wood or soft materials and provides a standard machine thread for various attachments.
• Concealed Connection: The lag screw end can be fully embedded, creating a strong, hidden connection within the substrate.
• Strong Hold: The coarse lag threads provide excellent grip and pull-out resistance in wood and other appropriate materials.
• Wide Range of Applications: Suitable for a variety of uses, from furniture assembly to hanging fixtures and connecting components.
• Easy to Use: Installation into a pre-drilled pilot hole is straightforward using a hex drive (if present), nut, or double-nutting method on the machine screw end.

Applications

• Furniture Assembly: Commonly used to assemble furniture components, such as attaching legs to tables or securing shelves.
• Mounting Fixtures: Ideal for mounting items like mirrors, picture frames, and wall art to wooden studs, providing a strong anchor point.
• Cabinetry and Joinery: Used in cabinet construction and other woodworking projects where a strong, concealed connection is required for external components.
• Suspension Systems: Can be used to hang items from wooden beams or ceilings, providing a threaded stud for hooks or eye nuts.
• Connecting Materials: Facilitates the connection of various materials by creating a secure threaded interface between wood and metal or other machine-threaded components.
