(100pcs) M3 x 8 mm Nylon Washer, (ID:3.4mm OD:8mm T:1mm), White

Overview

The M3 x 8 mm Nylon Washer (ID:3.4mm OD:8mm T:1mm) is an essential non-conductive hardware component engineered for electrical isolation, vibration damping, and surface protection. Unlike traditional metal washers that conduct electricity and can scratch sensitive finishes, these durable engineering-grade nylon washers provide a protective barrier between metal fasteners and delicate substrates.

Electrical Insulation & Short-Circuit Prevention

When mounting printed circuit boards (PCBs), electronic modules, Raspberry Pi/Arduino boards, or power supplies, metal-to-metal contact can cause accidental short circuits and electrical failures. Nylon is a natural dielectric material that completely isolates fasteners from conductive traces, protecting sensitive electronics and preventing ground loops.

Vibration Damping & Non-Marring Clamping

Directly clamping steel screws against acrylic, glass, carbon fiber, or 3D-printed plastics often leads to stress concentration, cracking, or surface marring. The semi-flexible resilience of nylon allows the washer to absorb clamping torque, cushioning the fastener head and evenly distributing load pressure without damaging the host material. Furthermore, its inherent dampening properties help resist fastener loosening caused by operational vibrations.

Common Applications

• Electronics & PCB Mounting: Isolating circuit boards from metal chassis, standoffs, and enclosure floors.

• 3D Printers & CNC Machines: Protecting printed plastic parts, acrylic windows, and sensor mounts from screw head damage.

• Drones & RC Models: Acting as lightweight vibration dampening spacers for flight controllers, camera gimbals, and carbon fiber frames.

• General Workshop & Appliance Repair: Serving as non-corrosive shims, gap spacers, or insulating washers where moisture and rust are a concern.
