Reliable M12 Fastening Support for Electrical Distribution Assemblies
The ABB ZX281P10 provides a straightforward mechanical locking function in compatible M12 fastening assemblies. Its external-tooth profile is designed to grip the adjacent surfaces when compressed beneath a correctly tightened fastener, helping resist unwanted loosening during normal service.
Unlike a plain washer, which primarily distributes clamping force over a larger surface area, an external-tooth locking washer uses its formed teeth to create additional resistance to relative movement. This makes the ZX281P10 suitable for selected mechanical fastening arrangements in electrical distribution equipment where the manufacturer specifies this washer type.
The washer conforms to the DIN 6798 Form A configuration. This standardised geometry helps installers identify the appropriate external-tooth washer for M12 fastening applications and distinguish it from plain washers, split spring washers and internal-tooth locking washers.
ABB specifies an electrolytically galvanised surface finish for the ZX281P10. The zinc coating provides corrosion resistance appropriate to the intended application and installation environment. The finished washer has a nominal external width of 21.7 mm, an overall height of 2.7 mm and a material thickness of 1 mm.
Within electrical distribution panel construction, correct mechanical fastening is important for maintaining the intended positioning of mounting components, support brackets and associated equipment. The ZX281P10 can form part of these assemblies where an M12 external-tooth washer is specified by the applicable ABB installation instructions.
When installed, the washer should be positioned between the appropriate fastening surface and bolt head or nut. Fasteners must be tightened to the torque specified for the complete assembly. The washer itself does not determine the tightening torque, which depends on the fastener, joint materials and equipment manufacturer's requirements.
For applications involving electrical bonding or protective earth continuity, the use of a toothed washer alone must not be assumed to establish a compliant electrical connection. The complete bonding arrangement must be approved for that purpose, taking account of surface coatings, contact pressure and the applicable installation requirements.
The ZX281P10 is supplied in packs of 10, providing a convenient quantity for panel-building work, maintenance activities and installations requiring several matching M12 locking washers. The pack format helps installers maintain consistency across multiple approved fastening positions.
