Uxcell 400-Piece M5 Nylon Flat Washers - 10mm OD, 5mm ID, 1mm Thick Insulating Spacers For Electronics & Fasteners

Need small, non-conductive washers for electronics, DIY projects, or general fastening? This pack of 400 nylon flat washers is super handy. Each washer is M5 size: 10mm outer diameter, 5mm inner diameter, and 1mm thick—perfect for standard M5 bolts and screws.

Made from durable nylon, they’re great for insulating electrical connections (like between a motherboard and metal standoffs), distributing load under nuts/bolts, or acting as spacers or shims. The grey-white color is neutral and low-profile.

Lightweight, corrosion-proof, and affordable. Keep a stash in your toolbox, workshop, or repair kit. Whether you’re building a PC, fixing furniture, or tinkering with gadgets, these little washers prevent shorts, reduce vibration, and protect surfaces. A tiny part that makes a big difference!
