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.

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

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.
Automotive and Aerospace: Lightweight yet strong, perfect for assemblies requiring frequent adjustments.
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.

Design Features

The Polished Aluminium Captive Star Knob is designed for both functionality and aesthetics:

Polished Aluminium Construction: Combines strength, lightweight properties, and corrosion resistance for long-lasting performance.
Star Knob Design: Features an ergonomic shape for a secure grip, making adjustments simple and efficient.
Captive Shank Design: Ensures the knob remains attached to the assembly for reliable and hassle-free operation.
Polished Finish: Offers a sleek, professional appearance while being resistant to wear and corrosion.
