Discover more about the Metric Slotted Knob Captive Panel Screws range.
Metric slotted knob captive panel screws are precision-engineered fasteners designed to secure removable panels without the risk of loss during maintenance or operation. These specialist captive screws combine a spring-loaded screw housed within a ferrule, topped with an easy-to-grip slotted knob or drive. Once installed, the fastener remains captive within the outer panel, ensuring efficiency, reliability and ease of access in demanding engineering environments.
Commonly used across sectors such as electronics, manufacturing and mechanical assembly, these components deliver repeatable performance where panels need to be removed and reinstalled frequently, making them indispensable for service panels, control units and instrument enclosures.
How Metric Slotted Knob Captive Panel Screws Work
Metric slotted knob captive panel screws work through three main components: a ferrule, spring-loaded screw and knob with integrated slotted drive.
The ferrule, available with different tips mentioned below, is installed by insertion into a pilot hole in a panel. This ferrule then houses a spring-loaded screw, which is captive within the ferrule. Finally, the knob and integrated drive allow the screw to be turned. As force and rotation are applied to the knob, it depresses the spring, exposing the threads of a screw, ready to interact with other threaded components.
For example, in an electronics enclosure, a metric slotted knob captive panel screw can be loosened by hand to remove a cover plate, then retightened without risk of misplacement. This maintains both accessibility and security. The integrated spring mechanism ensures smooth, consistent operation and prevents over-travel when fully engaged.
Materials Metric Slotted Knob Captive Panel Screws Are Made From
Due to their multi-component design, these fasteners are manufactured from a combination of high-quality metals. Each material contributes unique mechanical advantages to the complete assembly:
- Steel: Provides exceptional tensile strength and durability, making it ideal for load-bearing applications.
- Aluminium: Offers lightweight performance and natural corrosion resistance, ensuring smooth operation even in environments sensitive to weight or vibration.
- Stainless Steel: Delivers long-lasting protection against corrosion and wear.
Because each part of the assembly serves a different function, the material composition varies between components. As a result, your selection is typically based on installation type and functional requirements rather than material preference alone.
Sizes and Types of Metric Slotted Knob Captive Panel Screws Available
Accu’s metric slotted knob captive panel screws are available in thread sizes ranging from M3 (3mm) to M6 (6mm), offering versatility for a wide range of panel thicknesses and applications.
Installation types include:

- PC Board: Ideal for printed circuit boards and fibreglass composites.
- Press In: Offering a flush fit for sheet metal.
- Snap In: Allowing tool-free installation.
Each variant features a slotted drive for easy manual or tool-assisted tightening, with screw protrusion lengths ranging from 3.8mm to 12.6mm when fully depressed.
FAQs
Q: What is the advantage of a slotted drive on a captive panel screw?
A: The slotted drive offers versatility. It can be operated by hand using the knob or with a standard flat-blade screwdriver. This makes it particularly useful in maintenance applications where accessibility and speed are key.
Q: Are slotted knob captive panel screws suitable for use with power tools?
A: Although possible, it’s not recommended. The slotted drive is designed primarily for hand tool use. Over-torqueing with power tools may damage the slot or ferrule.
Q: Do slotted knob captive panel screws require special installation tools?
A: Depending on the installation type, most variants, such as Snap In or Press In, can be installed manually or with standard hand tools.
Q: Can these screws be used in PCBs and fibreglass panels?
A: Yes. PC board installation types are specifically designed for composites such as printed circuit boards and fibreglass, ensuring a secure fit without damaging delicate materials.
