Professional Applications & Engineering Value
These M3 clear polycarbonate flat washers deliver critical engineering advantages in demanding applications where metal components would fail. The polycarbonate plastic construction eliminates galvanic corrosion when used with dissimilar metals, while the transparent design allows for visual verification of proper seating and alignment. Engineered to DIN 433 standards, these washers provide consistent dimensional accuracy for M3 fasteners, ensuring reliable performance in electrical enclosures, medical devices, and food processing equipment where chemical resistance and temperature stability (-40°F to 220°F) are paramount. The Rockwell R120 hardness offers optimal load distribution without embrittlement, making them ideal for vibration-prone assemblies where repeated stress cycling occurs.
Specification Summary & Compliance
This metric flat washer features precise dimensions: 3.2mm ID, 6mm OD, and 0.5-0.6mm thickness, engineered to DIN 433 standards for dimensional consistency. Manufactured from polycarbonate plastic with Rockwell R120 hardness, the washers comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety requirements for industrial applications worldwide.
