Word: Allen Screw

Definition: An Allen screw is a type of screw that has a hexagonal hole in its head. This means that instead of a straight slot or a Phillips (cross) shape, the top of the screw is shaped like a six-sided figure (hexagon), which allows a special tool called an Allen wrench or hex key to be used to turn it.

Usage Instructions:

1. How to Use: To tighten or loosen an Allen screw, you need an Allen wrench, which fits into the hexagonal hole. Turn the wrench in the direction you want to go:

   • Clockwise to tighten (make it stronger or hold something in place).
   • Counterclockwise to loosen (remove or adjust something).

2. Where to Find Them: Allen screws are commonly used in furniture assembly, bicycles, and machinery because they provide a secure connection.

Example Sentence:

• "I needed an Allen wrench to fix the furniture because it had several Allen screws."

Advanced Usage:

• In engineering and design, Allen screws are appreciated for their ability to handle high torque without stripping, making them ideal for heavy-duty applications.

Word Variants:

• Allen Wrench: The tool used to turn Allen screws.
• Hex Key: Another name for the Allen wrench.

Different Meanings:

• While "Allen screw" specifically refers to the screw with a hexagonal hole, "Allen" can also refer to a person's name, but in the context of tools and hardware, it strictly pertains to the screw type mentioned.
