S-95481A171 3.2 mm ID x 14 mm OD Finishing Washers

Key Features & Benefits at a Glance

• Exceptional corrosion resistance due to nylon plastic construction, ideal for harsh environments where metal washers would degrade
• Secure, flush fastening with a precise 90° countersink angle that seamlessly accommodates standard countersunk screw heads
• Superior surface protection from the rounded face design, which helps distribute load and prevent damage to sensitive materials
• Reliable performance across a wide temperature range, maintaining integrity from -40°F to 180°F for versatile application use
• Consistent dimensional stability with a Rockwell R120 hardness, ensuring the washer retains its shape and function under pressure
• Guaranteed material safety and compliance, meeting RoHS 3 and REACH standards for use in regulated industries
• Perfect fit for M3 screws with a 3.2mm ID and 14mm OD, providing precise alignment and secure fastening in metric assemblies

Professional Applications & Engineering Value

This M3 nylon countersunk washer is engineered to solve common industrial challenges, such as galvanic corrosion and component wear. The nylon plastic material provides excellent electrical insulation and resistance to chemicals, making it ideal for electrical enclosures, automotive assemblies, and consumer electronics. Its 90° countersink angle ensures a smooth, flush finish with countersunk screw heads, eliminating protrusions that could snag or cause injury. The rounded face minimizes stress concentration on surfaces, protecting delicate substrates from cracking or deformation. With a temperature resistance from -40°F to 180°F, it performs reliably in both freezing and moderately high-heat environments, offering a durable, lightweight alternative to metal washers that reduces overall assembly weight without sacrificing strength.

Specification Summary & Compliance

This metric washer features precise dimensions with an Inside Diameter (ID) of 3.2 mm and Outside Diameter (OD) of 14 mm, designed for M3 screw sizes to ensure accurate fit. It adheres to standard metric system specifications, with a countersink angle of 90° for compatibility with common fasteners. The washer is manufactured from nylon plastic with a Rockwell R120 hardness for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted substances and safe for industrial and consumer applications.
