What are captive hand knobs?

Captive hand knobs, like the Polished Aluminium Captive Star Knobs, 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 polished aluminium, these knobs are lightweight, corrosion-resistant, and offer a sleek, professional appearance.

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 aluminium construction provides excellent strength while being easy to handle.
• Professional Appearance: The polished finish adds a sleek, modern look to any assembly.
