Key Features & Benefits at a Glance
- Superior electrical insulation properties from nylon plastic material prevent current leakage in electrical assemblies
- Excellent vibration dampening characteristics reduce noise and prevent fastener loosening in high-vibration environments
- Wide temperature tolerance from -40°F to 180°F maintains performance across diverse industrial conditions
- Precise dimensional fit with 0.379" ID ensures secure mounting on 3/8" screws without slippage
- Enhanced durability with Rockwell R118 hardness resists deformation under load and repeated use
- Chemical resistance of nylon material protects against corrosion from oils, solvents, and mild chemicals
- Regulatory compliance with RoHS 3 and REACH standards ensures safe use in regulated industries
Professional Applications & Engineering Value
This nylon sleeve washer delivers critical engineering solutions where electrical insulation and vibration resistance are paramount. The off-white nylon plastic construction provides excellent dielectric properties while the extended 1.125" overall height with 1" sleeve height offers superior isolation between mating surfaces. Industrial engineers specify these 3/8 inch screw washers for electrical enclosures, machinery assemblies, and automotive applications where thermal stability (-40°F to 180°F) and chemical resistance are essential. The 0.535" OD provides ample bearing surface while the precise 0.379" ID ensures secure fitment, preventing movement that could compromise electrical safety or mechanical integrity in demanding environments.
Specification Summary & Compliance
This inch system sleeve washer features precise dimensions: 0.379" ID, 0.535" OD, and 1.125" overall height with 1" sleeve height.
