S-91145A233 0.171" ID x 0.345" OD Insulating Washers

Key Features & Benefits at a Glance

• Superior electrical insulation and corrosion resistance from Nylon 6/6 material, ideal for preventing galvanic corrosion and electrical shorts in sensitive assemblies.
• Excellent vibration dampening and load distribution due to the plastic construction, protecting fastened components from wear and loosening.
• Reliable performance across extreme temperatures, maintaining integrity from -40°F to 180°F for use in harsh indoor and outdoor environments.
• Rockwell R108 hardness provides a durable, non-marring surface that resists deformation under pressure.
• Precision sleeve design with a 0.209" OD ensures a secure fit and consistent alignment for No. 8 screws.
• Compliance with RoHS 3 and REACH regulations guarantees safety and environmental responsibility for global supply chains.
• Off-white color offers a clean, professional appearance and easy identification in inventory.

Professional Applications & Engineering Value

This Nylon 6/6 plastic sleeve washer is engineered to solve common industrial challenges where metal fasteners fall short. Its inherent properties eliminate the risk of galvanic corrosion when used with dissimilar metals, a critical advantage in electrical enclosures, automotive assemblies, and marine equipment. The sleeve design provides superior alignment and prevents screw head pull-through in soft materials, enhancing joint integrity. With a temperature range of -40°F to 180°F, it performs reliably in applications from freezer units to engine compartments, offering a lightweight, non-conductive alternative that reduces overall assembly weight without sacrificing the durability demanded by B2B technical specifications.

Specification Summary & Compliance

This washer features an ID of 0.171", OD of 0.345", and thickness of 0.062" with an overall height of 0.109", designed for a No. 8 screw size in the inch system.
