A flat head plum barrel nut (也稱為 barrel nut 或 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:
功能:
-
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).
-
-
材質:
-
通常由 steel (often zinc-plated or stainless steel for corrosion resistance) or brass for decorative or non-magnetic applications.
-
-
安裝:
-
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.
-
常見用途:
-
Furniture & Cabinetry: Used in flat-pack furniture for hidden joints.
-
Automotive & Aerospace: Securing panels or components with minimal protrusion.
-
電子與機箱: Fastening internal components without exposed hardware.
-
DIY & Metalworking: When a smooth surface is required after assembly.
優勢:
-
Low-profile finish (flush with the surface).
-
Strong grip due to the barrel shape distributing load.
-
Easy to conceal for aesthetic applications.
