• Precise dimensional fit with 0.406" ID specifically designed for 3/8" screws, ensuring secure fastening and load distribution
• Durable 65D Durometer hardness provides optimal balance between flexibility and crush resistance for long service life
• Comprehensive regulatory compliance with RoHS 3 and REACH standards for use in regulated industries and global markets
• Temperature stability maintaining performance up to 140°F (60°C) in various operating conditions
• Non-marring and non-conductive properties protect sensitive surfaces and prevent electrical shorts in assembly applications

Professional Applications & Engineering Value

These PVC plastic flat washers deliver critical engineering solutions where chemical resistance and electrical insulation are paramount. The gray PVC material withstands exposure to various chemicals, acids, and solvents that would corrode metal alternatives, making them ideal for chemical processing, water treatment, and marine applications. With their Durometer 65D hardness, these washers maintain structural integrity under compression while providing sufficient flexibility to accommodate minor surface irregularities. The precise 0.406" ID ensures proper fitment for 3/8" screw size applications, distributing load evenly and preventing fastener loosening in vibrating environments. These industrial washers are particularly valuable in electrical assemblies where their non-conductive properties prevent current leakage and protect against galvanic corrosion between dissimilar metals.

Specification Summary & Compliance
