What are captive hand knobs?

Captive hand knobs, like the Bakelite Captive Thumb Screw, 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 Bakelite, these knobs provide excellent heat resistance, rigidity, and a classic aesthetic.

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.
Heat Resistance: Bakelite construction offers exceptional performance in high-temperature environments.
Durability: Resistant to wear and deformation, ensuring long-lasting use.

What industries and applications are captive products used in?

Captive thumb screws are widely used in various industries, including:

Manufacturing: Ideal for jigs, fixtures, and machine components requiring secure and adjustable fastening.
Electronics and Electrical: Excellent insulating properties make Bakelite suitable for electrical equipment and enclosures.
Automotive and Aerospace: Heat-resistant and lightweight, perfect for high-performance assemblies.
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 Bakelite Captive Thumb Screw is designed for both functionality and aesthetics:

Bakelite Construction: Combines high rigidity, heat resistance, and durability, making it ideal for demanding environments.
Thumb Screw Design: Offers a smooth, ergonomic grip for precise adjustments and ease of use.
Captive Shank Design: Ensures the screw remains attached to the assembly for reliable and hassle-free operation.
Classic Appearance: The Bakelite material provides a timeless look while being resistant to scratches and wear.
