S-96100A157 0.93" ID x 1.25" OD Plastic Washers

Key Features & Benefits at a Glance

• Exceptional Durability: Rockwell R70 hardness provides superior resistance to deformation under load, ensuring long-term performance in demanding applications.
• Reliable Electrical Insulation: Made from hard fiber, this washer offers excellent non-conductive properties, making it ideal for electrical assemblies.
• High-Temperature Resistance: Withstands temperatures up to 230°F, maintaining structural integrity in environments with thermal fluctuations.
• Precise Fit for 7/8" Screws: 0.93" ID ensures a secure and accurate fit, reducing installation time and preventing loosening.
• Optimal Load Distribution: 1.25" OD and 0.120-0.130" thickness help distribute pressure evenly, protecting surfaces and extending component life.
• Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring safety and environmental responsibility for global supply chains.
• Corrosion-Resistant & Non-Marring: Black hard fiber material resists corrosion and will not damage sensitive surfaces during tightening.

Professional Applications & Engineering Value

This hard fiber flat washer is engineered to address common industrial challenges such as electrical short-circuit risks, surface damage from metal fasteners, and component failure under thermal stress. The Rockwell R70 hardness ensures it maintains its shape under high clamp loads, while the fiber material provides inherent electrical insulation—critical in panel building, switchgear, and motor applications. Its 0.93" ID is precision-sized for 7/8" screws, offering a snug fit that minimizes vibration-induced loosening. The ability to perform in temperatures up to 230°F makes it suitable for automotive, machinery, and HVAC systems where thermal cycling is a concern. The black finish and fiber composition also prevent galvanic corrosion when used with dissimilar metals.
