A flat head plum barrel nut (として知られている。 barrel nut または 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:

   • 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. 素材：

   • 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.

• 自動車と航空宇宙 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.

利点がある：

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

• Strong grip due to the barrel shape distributing load.

• Easy to conceal for aesthetic applications.
