## Long description

Grounding washer M5 by SCHROFF is supplied as a pack of 100 and is designed for M5 threaded connections to ensure reliable electrical grounding and secure mechanical mounting in electronic and industrial assemblies. The washer provides a consistent metal-to-metal contact surface for chassis, racks and equipment where effective earthing and vibration-resistant fastening are required. Its profile and material selection are optimized for repeatable performance in grounding paths and for use in environments where secure electrical continuity is essential.
Advantages
The grounding washer ensures consistent electrical contact and reduces contact resistance at M5 connections, supporting effective earthing of metal enclosures and equipment. Supplied in a pack of 100, it streamlines installation and spare-part management for series builds and maintenance. The washer’s design offers mechanical stability to threaded joints, helping to resist loosening under vibration and thermal cycling while maintaining conductive continuity.
Suitable for
 Chassis and cabinet earthing in electronic equipment
 Rack-mounted systems and server enclosures
 Industrial control panels and switchgear
 Grounding connections in power distribution assemblies
 Maintenance and spare-part kits for repeated installations
Key specifications
 Thread size: M5 compatible
 Pack quantity: 100 pieces
 Function: electrical grounding and mechanical locking for threaded connections
 Typical material: conductive metal suitable for earthing contact (metal finish dependent on variant)
 Application environment: electrical and electronic assemblies, industrial racks and enclosures
How to use
Place the grounding washer on the M5 screw or stud so that the washer sits flat against the mating surface before tightening the nut or screw. Tighten to the appropriate torque for the M5 fastener, ensuring firm metal-to-metal contact without over-torquing, which could deform the washer or mating threads. Verify electrical continuity with a multimeter after installation if required by the application’s earthing protocol. Replace washers during maintenance or when signs of corrosion or mechanical wear are present.
Usage recommendations
Store the pack in a dry environment to avoid corrosion. Use with clean, paint-free contact areas where possible to maximize conductivity. When used in high-vibration environments, combine with appropriate locking nuts or verify torque periodically to maintain secure grounding connections.
