A hexagon cap 螺帽 (也稱為 hex cap nut 或 acorn nut) is a type of fastener that combines the features of a standard hex nut with a domed, capped end. Here’s a detailed description:

Features:

1. Hexagonal Body – Like a standard hex nut, it has six flat sides for easy tightening or loosening with a wrench or socket.

2. Domed Cap – One end is closed with a smooth, rounded cap, giving it an “acorn-like” appearance. This cap covers the exposed end of a bolt or threaded rod for safety and aesthetics.

3. 材質 – Typically made from steel (plain, zinc-plated, or stainless), brass, or nylon.

4. Finish – Available in various finishes, including plain, zinc-plated, chrome, or black oxide.

優勢：

• Appearance – Provides a clean, finished look in visible applications.

• Protection – Helps shield threads from dirt, moisture, and damage.

• Hexagon Cap Nut

Common Uses:

• Furniture assembly – Where exposed bolts need a polished look.

• Automotive & machinery – Covers wheel studs or other threaded ends.

• Electrical & plumbing – Used in fixtures for a neat appearance.

• Decorative applications – In railings, signage, or architectural metalwork.

Variations:

• Low-profile cap nuts – Shorter dome height.

• Nylon-insert cap nuts – Include a locking feature to prevent loosening.

• Knurled cap nuts – Allow hand-tightening without tools.
