A4-70 SS Pan Head Screws with Lock Washers 316 Stainless Spring + Flat Washer Salt Water Resistant Custom

High-quality Hex Standoffs for PCB mounting & electronic assembly. Multiple sizes (M2-M12), brass/stainless steel materials, nickel-plated. Custom lengths & threads. Secure component spacing solutions.  

Hex Standoffs are essential hardware for creating precise space between components in electronics, machinery, and industrial assemblies. Featuring a hexagonal body for easy wrench installation, these spacers provide sturdy support and reliable electrical isolation. Available in standard and **customizable sizes**, materials, and thread types to fit diverse project requirements. Ideal for PCB stacking, enclosure mounting, and vibration-resistant structures.  

Typical Applications: 

- PCB Stacking & Motherboard Mounting  
- Server Racks & Network Enclosures  
- Robotics & Drone Frames  
- Industrial Control Panels  
- Automotive Electronics  
- Heat Sink & Component Isolation  

Materials & Finish:
- **Brass:** Cost-effective, excellent conductivity, nickel-plated for oxidation resistance.  
- **Stainless Steel:** Superior strength, salt/fume resistance, passivated or black oxide finish.  
- **Optional Finishes:** Gold plating (high conductivity), Zinc plating (economical).  

How to Use:

1. Align standoff between mounting holes.  
2. Hand-tighten using hex wrench for initial grip.  
3. Secure with torque ≤ 5 Nm (brass) or 10 Nm (stainless steel) to prevent stripping.  
4. Stack components and fasten with screws.
