Cup point set screws, also known simply as set screws, are threaded fasteners designed to secure an object within or against another object. They are commonly used to prevent relative motion between two components, such as shafts and gears, or to fix an object in a specific position.
The “cup point” in cup point set screws refers to the fact that the end of the screw has a concave, or cup-shaped, indentation. This indentation creates a point of contact with the surface it is pressing against, providing a secure grip and reducing the likelihood of slippage.
Key features of cup point set screws:
-
- Indented Tip: The cup-shaped point at the end of the screw is designed to embed into the material it is pressing against, enhancing grip and reducing the chance of loosening.
- Threaded Design: Set screws have threads along their entire length, allowing them to be tightened securely into a threaded hole.
- Hex Socket Head: Cup point set screws typically have a hexagonal socket head, which requires an Allen wrench or hex key for installation.
- Material: Set screws are commonly made from materials such as steel, stainless steel, or alloy steel, depending on the application requirements.
- Applications: These screws are widely used in various applications, including machinery, automotive, electronics, and construction, where a secure and stable connection is essential.
When using cup point set screws, it’s crucial to ensure that they are properly tightened to avoid issues such as unintentional loosening, which can lead to malfunction or damage of the assembled components. Additionally, selecting the appropriate size and material for the specific application is important to achieve optimal performance and reliability.
