Mounting kit EFB Elektronik 691099HQ — steel cage nut set, black and silver, 20× M6

The EFB Elektronik 691099HQ mounting kit is a set of steel fastening components in black and silver finishes designed for panel and chassis assembly. It includes captive (cage) nuts, plastic washers and pan-head screws sized for M6 threaded connections, providing the basic parts needed to secure equipment in racks, enclosures and electronic housings where M6 fastenings are required.

Advantages

The kit groups compatible M6 cage nuts, plastic washers and pan head screws in one package for straightforward installation. Steel cage nuts offer reliable thread engagement while the plastic washers help protect mating surfaces and reduce friction. Pan head screws with a Phillips drive provide a commonly used fastening method that is easy to install with standard tools.

Suitable for

• Mounting equipment in server racks and 19" enclosures
• Securing panels, chassis or electronic housings with M6 threads
• Field or workshop assembly where a matching set of fasteners is needed

When it may not be suitable

This kit is intended for applications that require M6 threaded fastenings; it is not suitable if different thread sizes (for example M4 or M8) are required. The included components are basic fastening parts and may not replace specialized or corrosion-resistant fasteners needed for harsh environments or specific mechanical load requirements.

Key specifications

• Contents: captive (cage) nuts, plastic washers, pan head screws
• Thread size: M6
• Screw thread length: 16 mm (thread portion); total screw length: 20 mm
• Screw head type: pan head with Phillips drive (PH3)
• Finish: mixed black and silver steel components; plastic washers
• Quantity: 20 sets

How to use

Place cage nuts into the appropriate square openings in the rack or chassis and ensure they are seated correctly. Fit a plastic washer onto each screw if surface protection or spacing is required, then insert and tighten the pan head screws into the M6 cage nuts using a PH3 Phillips screwdriver or compatible bit. Tighten to an appropriate torque for the equipment and application to avoid over‑stress of threads or components.

What to consider before purchase

• Verify that M6 thread size and screw length are compatible with your mounting depth and panel thickness
• Consider whether standard steel components and plastic washers meet environmental and corrosion resistance requirements
• Confirm quantity (20 sets) is sufficient for your project

Usage recommendations

For routine rack and chassis assembly, use a calibrated PH3 screwdriver or torque-controlled driver and check that cage nuts are fully seated before applying load. If the application is exposed to moisture or corrosive conditions, select corrosion-resistant fasteners appropriate for the environment.
