Flat head plum barrel nut

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It 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 flat head plum barrel nut (also known as a barrel nut or pear-shaped nut) is a specialized type of fastener designed for specific applications where a low-profile, secure, and often concealed connection is needed. Here’s a detailed description:

Features:

1. Shape & Design:

   • Flat Head: The top surface is flat or slightly countersunk, allowing it to sit flush with or below the material surface when installed.

   • Plum/Barrel Body: The nut has a rounded, barrel-like (or pear-shaped) body with internal threads.

   • Slotted or Hex Drive: Many flat head barrel nuts have a slotted drive (for screwdriver installation) or a hex socket (for Allen/hex key tightening).

2. Material:

   • Typically made from steel (often zinc-plated or stainless steel for corrosion resistance) or brass for decorative or non-magnetic applications.

3. Installation:

   • Designed to fit into a pre-drilled or recessed hole, providing a low-profile fastening solution.

   • Often used in furniture assembly, automotive panels, machinery, and electronics where a flush finish is desired.

Common Uses:

• Furniture & Cabinetry: Used in flat-pack furniture for hidden joints.

• Automotive & Aerospace: Securing panels or components with minimal protrusion.

• Electronics & Enclosures: Fastening internal components without exposed hardware.

• DIY & Metalworking: When a smooth surface is required after assembly.

Advantages:

• Low-profile finish (flush with the surface).

• Strong grip due to the barrel shape distributing load.

• Easy to conceal for aesthetic applications.

• Flat head plum barrel nut

Variations:

• Slotted Flat Head Barrel Nut: For screwdriver installation.

• Hex Socket Barrel Nut: For Allen/hex key tightening.

• Shoulder Barrel Nut: Includes a shoulder for added stability.
