A barrel nut is a type of fastener used to join two or more parts together, often providing a cleaner look or a stronger connection than traditional nuts. It is a cylindrical, internally threaded component that works with a male-threaded screw or bolt. Depending on the application, a barrel nut can be used for general assembly in furniture or signage, or in more specialized roles, such as a self-locking fastener in aircraft structures or securing a firearm's barrel to its receiver.
The Cross Dowel Centre Thread Furniture Barrel Nut is a versatile cylindrical fastener designed for secure, concealed joining of multiple components. Featuring internal threading and a compact design, this barrel nut works seamlessly with male-threaded screws or bolts to deliver stronger connections than traditional nuts—ideal for applications where aesthetics and durability are equally important. Available in materials like stainless steel, carbon steel, and brass, it complies with ISO, GB, DIN, and ANSI standards, making it suitable for furniture, aerospace, and construction projects. Whether assembling ready-to-assemble furniture or securing aerospace components, this fastener offers reliable performance and a clean finish.
Engineered for thick joints, the cross dowel barrel nut creates a self-wrenching, self-locking attachment point that excels in high-tensile applications—from aircraft wings to heavy furniture frames. Its design ensures resistance to loosening under load.
By eliminating the need for long, through-drilled bolts (no full penetration required), this fastener reduces material usage, weight, and overall project costs. It enables secure joining without compromising component integrity.
Compatible with high-strength bolts and a wide range of base materials (wood, metal, plastic), the furniture barrel nut adapts to diverse applications—from stainless steel aerospace components to wooden furniture panels.
Unlike exposed nuts, this barrel nut is installed within the component, providing a clean, professional finish. This makes it perfect for furniture, signage, and visible structures where unsightly fasteners are undesirable.

Used to join load-carrying components in aircraft, such as landing gear to fuselages, engine pods to wings, and control surfaces—relying on its high-strength self-locking properties.
Ideal for ready-to-assemble furniture (beds, cribs, chairs, cabinets), door hardware (hinges, push plates), and woodworking projects. It provides concealed, secure fastening that preserves the furniture’s aesthetic appeal.
Employed in construction projects for joining structural components, as well as in signage, display fixtures, and custom hardware installations where hidden, durable connections are needed.
Test Bolt-Nut Fit: Thread the bolt in and out of the barrel nut to ensure compatibility. Zinc plating may cause minor thread buildup—apply a small amount of oil if needed for smooth installation.
Gather Tools: Prepare a drill (matching bolt/nut size), appropriate screwdriver, and furniture connector bolt.
Drill Bolt Hole: Align the two components to be joined (e.g., wood panels) and drill a bolt hole through one component and partially into the other.
Drill Crosswise Dowel Hole: Drill a crosswise hole (perpendicular to the bolt hole) to fit the barrel nut’s diameter—ensure the hole depth matches the nut’s length.
Drive Barrel Nut into Place: Use a screwdriver to insert the cross dowel barrel nut into the crosswise hole until its internal threads align with the bolt hole.
Tighten Connector Bolt: Insert the furniture connector bolt through the bolt hole and into the barrel nut. Tighten firmly to secure the two components—ensure a snug fit without over-tightening.
