What are captive hand knobs?

Captive hand knobs, like the Captive Star Knob with Matt Finish, are versatile components designed for quick and secure adjustments. Unlike standard threaded hand knobs, these feature a plain shank portion without threading, enabling a captive fit when used in conjunction with compatible washers or just a threaded hole in the front panel. The captive functionality ensures that the knob remains attached to the assembly, even when fully loosened, preventing loss or misplacement.

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 make adjustments without worrying about completely removing or losing the knob.
Safety Compliance: Ideal for industries requiring tamper-proof or secure fastening to meet health and safety regulations.
Efficiency: Streamlines operations by minimising the need to replace lost components, saving costs and time.

What industries and applications are captive products used in?

Captive hand knobs find extensive use across multiple industries, including:

Manufacturing: For jigs, fixtures, and machine setup where quick adjustments are necessary.
Aerospace and Automotive: Ensuring secure assembly components that comply with safety standards.
Electronics and Enclosures: Keeping panels or covers in place while allowing easy access for maintenance.
Furniture and Exhibits: For modular or adjustable components that require reliable retention.

Common applications include fastening panels, adjusting machine components, and securing removable parts.

Design Features

The Captive Star Knob with Matt Finish is carefully engineered for both functionality and aesthetics:

Metric Coarse Threads: Features coarse metric threads for compatibility with a wide range of applications, ensuring quick and secure fastening.
Compatibility with WDS 899 Threaded Washers: Designed to pair seamlessly with WDS 899 threaded washers, which enhance captive functionality and secure attachment.
Durable Matt Finish: The matt surface not only adds a professional appearance but also improves wear resistance and ease of cleaning.
Ergonomic 4-Lobe Design: The four-lobe shape provides a comfortable grip for precise adjustments and efficient operation.
