What are captive hand knobs?

Captive hand knobs, like the Matt 316 Stainless Steel Knurled Thumb 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 316 stainless steel, these knobs provide excellent strength, corrosion resistance, and durability.

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.
Durability: 316 stainless steel construction ensures superior corrosion resistance and longevity, even in demanding environments.
Efficiency: Saves time and costs by eliminating the need to replace lost or detached parts.

What industries and applications are captive products used in?

Captive knurled thumb knobs are widely used in various industries, including:

Manufacturing: Ideal for jigs, fixtures, and machine components requiring secure and adjustable fastening.
Marine and Offshore: Exceptional corrosion resistance makes them perfect for saltwater environments.
Food and Pharmaceutical: Suitable for hygienic environments due to the stainless steel material.
Electronics and Enclosures: Used to secure panels, covers, and access points in various assemblies.

Common applications include securing panels, adjusting fixtures, and clamping parts in adjustable assemblies.

Design Features

The Matt 316 Stainless Steel Knurled Thumb Knob is designed for both functionality and aesthetics:

316 Stainless Steel Body: Provides outstanding strength, corrosion resistance, and a long service life in harsh or hygienic environments.
Matt Finish: Offers a subtle, modern appearance with excellent wear resistance and reduced glare.
Knurled Grip Design: Features a textured surface for enhanced grip, allowing precise adjustments with ease.
Captive Shank Design: Ensures the knob remains attached to the assembly for reliable and hassle-free operation.
