M10 x 25 Thermoplastic star knobs captive thread

What are captive hand knobs?

Captive hand knobs, like the Thermoplastic Captive Star Knob, are versatile components designed for secure and adjustable fastening. Unlike standard threaded knobs, these feature a plain shank section without threading, allowing them to remain attached to the assembly even when fully loosened. This "captive" functionality ensures reliability and prevents loss during operation. Made from durable thermoplastic, these knobs are lightweight, resistant to wear, and suitable for various environments.

What advantages does captive functionality have?

The captive design offers several key benefits:

• Loss Prevention: The knob remains fixed to the assembly, reducing downtime caused by misplaced components.
• Ease of Use: Operators can adjust the knob without worrying about detachment or loss.
• Lightweight and Durable: The thermoplastic material provides excellent strength while reducing weight, making it ideal for frequent use.
• Cost-Effective: Thermoplastic knobs offer a more economical solution compared to metal alternatives without compromising on quality.

What industries and applications are captive products used in?

Captive star knobs are widely used in various industries, including:

• Manufacturing: Ideal for jigs, fixtures, and machine components requiring secure and adjustable fastening.
• Electronics and Enclosures: Used to secure panels, covers, and access points in various assemblies.
• Furniture and Modular Systems: Lightweight and easy to use, perfect for ergonomic and adjustable clamping applications.
• General Assembly: Suitable for a wide range of fastening and adjustment tasks.

Common applications include securing panels, adjusting fixtures, and clamping parts in adjustable assemblies.
