Barrel nut

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. lt is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

A barrel nut, also known as a cross dowel nut, is a specialized fastener used in furniture assembly, particularly in ready-to-assemble (RTA) furniture. It is designed to create strong, hidden joints between two pieces of material, typically wood or particleboard. Here’s a detailed description:

Key Features:

1. Cylindrical Shape: Barrel nuts are cylindrical, resembling a small barrel, with a threaded hole running perpendicular to their length.
2. Threaded Hole: The hole is internally threaded to accommodate a bolt or screw.
3. Grooves or Slots: Many barrel nuts have grooves or slots on the outside to help grip the material and prevent rotation during installation.
4. Material: Typically made from metal (such as steel or zinc-plated steel) for durability and strength.
5. Sizes: Available in various sizes to match different bolt diameters and material thicknesses.

How It Works:

1. The barrel nut is inserted into a pre-drilled hole in one piece of material.
2. A bolt or screw is inserted through a hole in the adjoining piece of material and threaded into the barrel nut.
3. As the bolt is tightened, it pulls the two pieces of material together, creating a strong, secure joint.

Common Applications:

• Furniture Assembly: Widely used in assembling beds, desks, shelves, and cabinets.
• Modular Furniture: Ideal for flat-pack or RTA furniture.
• DIY Projects: Useful for creating sturdy joints in woodworking projects.

Advantages:

• Hidden Fastening: Provides a clean, finished look as the nut is concealed within the material.
• Strong Joints: Creates durable and stable connections.
• Ease of Assembly: Simplifies the assembly process for furniture and other structures.

Installation Tips:

• Ensure the holes for the barrel nut and bolt are aligned correctly.
• Use tighten the bolt securely.a hex key or Allen wrench to

Barrel nuts are an essential component in modern furniture design, offering a balance of strength, convenience, and aesthetics.
