S-95225A113 1.7 mm ID x 3.9 mm OD DIN 125 Plastic Washers

Key Features & Benefits at a Glance

• Exceptional electrical and thermal insulation due to hard fiber material, preventing current leakage and heat transfer in sensitive assemblies.
• Superior surface protection and vibration dampening with a Rockwell R70 hardness rating, reducing wear and noise in precision equipment.
• Reliable performance in high-temperature environments, withstanding up to 230°F (110°C) without degradation.
• Guaranteed dimensional accuracy and interchangeability through strict adherence to DIN 125 standards for consistent fit with M1.6 screws.
• Enhanced environmental and workplace safety with full compliance to RoHS 3 and REACH regulations, free from hazardous substances.
• Optimized for confined spaces with a compact 3.9mm OD and 0.2-0.3mm thickness, ideal for miniaturized electronic and mechanical designs.
• Corrosion-resistant and non-conductive properties of the black hard fiber ensure long-term durability in diverse industrial conditions.

Professional Applications & Engineering Value

These M1.6 metric flat washers are engineered to address critical challenges in precision assembly, where electrical isolation, thermal management, and space constraints are paramount. The hard fiber material provides excellent dielectric strength, making them ideal for electronic enclosures, circuit boards, and small instrumentation, preventing short circuits. Their low profile (0.2-0.3mm thickness) and compliance with DIN 125 ensure a perfect fit and uniform load distribution under M1.6 screws, reducing the risk of loosening due to vibration. The black surface finish offers consistent performance without marring sensitive components. By withstanding temperatures up to 230°F, these washers deliver reliable sealing and spacing in automotive sensors, telecommunications devices, and miniature actuators, extending service life and minimizing maintenance.
