• Consistent 1.5-1.7mm thickness provides uniform load distribution and reliable sealing performance

Professional Applications & Engineering Value

These UHMW plastic flat washers deliver critical engineering solutions where metal components would compromise performance. The off-white UHMW material offers superior chemical resistance against oils, solvents, and corrosive substances, making them ideal for chemical processing equipment, food machinery, and marine applications. Their non-conductive properties provide essential electrical insulation in control panels, electronic enclosures, and power distribution systems. The metric M6 specification with precise 6.4mm inner diameter ensures secure fastening without galvanic corrosion concerns in mixed-material assemblies. The low moisture absorption characteristic maintains dimensional stability in humid environments, while the smooth surface prevents damage to sensitive materials during tightening operations.

Specification Summary & Compliance

This metric flat washer features precise dimensional specifications: 6.4mm inner diameter, 12mm outer diameter, and 1.5-1.7mm thickness range, engineered for M6 screw applications.
