Overview
Designed for electronics engineers, PC builders, and hobbyists, this 250-piece M3 standoff kit provides a safe, lightweight solution for securing motherboards, circuit boards, and industrial equipment. Made from durable nylon and reinforced plastic, it eliminates electrical conductivity risks while offering versatile sizing and organized storage.

1. Material & Safety Features
Electrical Insulation: Nylon and plastic components prevent short circuits, ideal for sensitive devices like Raspberry Pi, Arduino, or custom PC builds.
Durability: Resists corrosion, UV exposure, and temperatures from -40°C to 120°C, suitable for indoor/outdoor use.
Lightweight Design: Reduces strain on thin PCBs or portable gadgets compared to metal hardware.

2. Kit Contents & Compatibility
Complete Assortment:
Standoffs/Spacers: Male-female threaded pillars (1~20mm).
Screws : M3 machine screws with flat heads.
Washers: Protect surfaces from abrasion.
Universal Fit: Compatible with #6-32 threads for U.S. electrical panels and standard M3 holes on PCBs/motherboards.

3. Key Applications
Computer Assembly: Secure motherboards, GPU brackets, or SSD trays without metal contact.
Industrial Equipment: Mount control panels, CNC machine components, or HVAC systems with vibration-resistant fasteners.
DIY Electronics: Perfect for drones, LED installations, or retro gaming console mods.

4. User-Friendly Design
Organized Storage: Durable compartment box with labeled sections for quick access.
Portability: Compact case (6.8” x 3.8” x 0.65”) fits in toolkits or workshop drawers.

5. Why Choose This Kit?
Cost-Effective: Avoid purchasing single-size packs – covers 90% of common mounting needs.
Time-Saving: Pre-sorted sizes eliminate mismatched hardware struggles.

6. Installation Tips
Align Components: Match standoff lengths to your PCB/motherboard mounting holes.
Secure with Screws: Hand-tighten to avoid stripping nylon threads.
Add Washers: For metal surfaces, use insulating washers to prevent contact.
