A flat head barrel nut is a type of fastener designed for specific applications where a low-profile, countersunk connection is needed. Here’s a detailed description:

Features:

1. Flat Head Design – The nut has a conical (tapered) underside that allows it to sit flush with the surface when installed in a countersunk hole.

2. Barrel Shape – The body of the nut is cylindrical (barrel-shaped), often with internal or external threading.

3. 線路類型 – Typically features internal threads (female threads) to accept a matching bolt or screw.

4. 材質 – Commonly made from steel (carbon or stainless), brass, or aluminum, depending on strength and corrosion resistance needs.

5. Drive Type – May include slots for a screwdriver, a hex socket, or another drive mechanism for installation.

6. Finish – Can be plain, zinc-plated, black oxide, or coated for corrosion resistance.

Common Uses:

• Countersunk Fastening – Used in applications where a smooth, flush surface is required (e.g., furniture, automotive panels, aerospace components).

• Barrel Nuts in Furniture – Often found in flat-pack furniture (like IKEA) for hidden, sturdy joints.

• Machinery & Automotive – Used in assemblies where space is limited and a low-profile fastener is necessary.

優勢：

• Provides a sleek, flush finish.

• Distributes load efficiently due to the tapered seat.

• Helps prevent snagging in moving parts.

• 平頭齒型桶狀螺帽

Disadvantages:

• Requires a countersunk hole, which may need precise machining.

• May have lower torque resistance compared to standard hex nuts.
