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.
