S-97215A107 0.171" ID x 0.414" OD Insulating Washers

Key Features & Benefits at a Glance

• Superior electrical insulation provided by nylon construction prevents current leakage and short circuits in electrical assemblies
• Excellent chemical resistance against oils, solvents, and most chemicals ensures long-term performance in harsh industrial environments
• Wide temperature tolerance from -40°F to 180°F maintains structural integrity across extreme thermal cycling conditions
• Precision dimensional stability with 0.171" ID and 0.354" cup ID ensures perfect fitment for No. 8 screws without loosening or misalignment
• Reduced component wear through Rockwell R120 hardness provides durable bearing surface that resists deformation under load
• Lightweight corrosion-proof solution eliminates galvanic corrosion concerns when used with dissimilar metals
• Environmental compliance assurance with RoHS 3 (2015/863/EU) certification meets global regulatory requirements for hazardous substances

Professional Applications & Engineering Value

This nylon sleeve washer delivers critical engineering advantages where traditional metal washers fail. The off-white nylon plastic construction provides essential dielectric properties for electrical applications while resisting corrosion in chemical processing environments. With its 0.171" ID precision-machined to match No. 8 screw specifications, this industrial washer prevents fastener loosening from vibration and thermal expansion. The sleeve design with 0.354" cup ID creates superior load distribution, protecting sensitive surfaces from damage while the Rockwell R120 hardness ensures dimensional stability under compression. Engineered for temperature extremes from -40°F to 180°F, this component maintains performance in outdoor, automotive, and HVAC applications where thermal cycling would compromise lesser materials.

Specification Summary & Compliance

This inch-system sleeve washer features precise dimensions including 0.171" internal diameter, 0.414" outer diameter, and 0.206" overall height with 0.040" wall thickness. Manufactured to exacting standards for No. 8 screw applications, the component demonstrates consistent dimensional accuracy across production batches. The washer is fully RoHS 3 (2015/863/EU) compliant, containing no restricted hazardous substances, and meets industry standards for plastic washers in mechanical and electrical assemblies.
