Material and function Material: Nylon — lightweight, corrosion-resistant, non-conductive, and low-friction. Function: Flat nylon washer designed to distribute load, protect mating surfaces, provide electrical insulation, and reduce abrasion between fasteners and parts. Sizes and compatibility Compatible with metric fasteners: M3, M4, M5, M6, M8, M10, M12, M14, M16, M18, M20, M22, M24. Available outer/inner dimensions correspond to the model designation (example: M3x6x1.2 = inner diameter 3 mm × outer diameter 6 mm × thickness 1.2 mm). Thickness options (mm): 1.2, 1.5, 2, 3 — choose the thickness that matches required spacing, compression, or insulation needs. Key benefits — why you need these washers Protects surfaces: Prevents scratching or deformation of plastics, painted finishes, and soft materials under fastener heads. Distributes load: Spreads clamping force to reduce localized stress and improve joint reliability. Electrical insulation: Non-conductive nylon isolates fasteners from conductive surfaces in electronics and appliances. Vibration damping and noise reduction: Nylon’s flex properties help absorb vibration and reduce rattle in assemblies. Corrosion resistance: Won’t rust or corrode, suitable for indoor and many non-immersion applications. Lightweight and low-profile: Useful where metal washers would add unwanted weight or interfere with clearances. Typical applications Electronics and appliances: Insulate screws from PCBs or metal chassis, preventing shorts and protecting components. Furniture and consumer products: Protect finishes and distribute load when fastening into soft materials or delicate surfaces. Light machinery and assemblies: Provide spacing, reduce wear at bearing points, and dampen vibration in small mechanical systems. How to choose the right washer Match the inner diameter to the fastener size (M3 uses ID 3 mm, M4 uses ID 4 mm, etc.). Select outer diameter and thickness based on the contact area needed and available clearance. Use 1.2–1.5 mm thickness for thin panels and light spacing; use 2–3 mm where extra insulation, spacing, or compression resistance is required.
