S-97725A263 0.174" ID x 0.312" OD Metal Sealing Washers

Key Features & Benefits at a Glance

• Lightweight and corrosion-resistant aluminum construction for extended service life in harsh or humid environments.
• Precise 0.174" ID and 0.312" OD dimensions ensure a perfect fit and reliable load distribution for No. 8 screws.
• Uniform 0.024-0.038" thickness provides consistent spacing and vibration dampening in assembled components.
• RoHS 3 and REACH compliant for safe use in global markets and environmentally sensitive applications.
• Ideal for electrical and lightweight assemblies where non-magnetic and non-sparking properties are critical.
• Flat washer design helps prevent surface damage and loosening under dynamic loads, enhancing joint integrity.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these aluminum flat washers offer exceptional corrosion resistance, making them ideal for outdoor, marine, and chemical-exposed applications. The 0.174" ID and 0.312" OD provide precise alignment with No. 8 screws, distributing clamp load effectively to prevent embedding and material fatigue. In electrical assemblies, the non-conductive and lightweight nature of aluminum reduces weight and minimizes galvanic corrosion risks. Their compliance with RoHS and REACH ensures they meet stringent environmental and safety standards, providing reliability in aerospace, electronics, and automotive sectors where material integrity is non-negotiable.
