Round Aluminum Standoff Spacer Aluminum Alloy Red Anodized Threaded Standoff Spacer

Description

What Are Aluminum Standoff Spacers?

Aluminum standoff spacers are cylindrical fasteners designed to maintain precise spacing and provide structural support between components in assemblies. They feature threaded or unthreaded configurations to secure PCBs, panels, or other parts while ensuring proper alignment, airflow, or insulation.

Aluminum Standoff Spacer: Specifications

1. Material

• 6061-T6 Aluminum: High strength-to-weight ratio, excellent machinability.

Excellent Case: High-Performance Gaming PC Cooling System

Challenge:
A gaming hardware company needed to reduce heat buildup in compact PC cases while ensuring secure GPU and motherboard mounting. Traditional plastic spacers deformed under high temperatures.

Solution:

• Installed hardcoat-anodized 6061-T6 standoffs (M5×10mm, male-female):

  • Thermal Management: Aluminum dissipated heat 5x better than plastic.

  • Stability: Withstood 90°C continuous operation without warping.

  • EMI Shielding: Anodizing reduced electrical interference.

Results:

• Lowered GPU temps by 12°C under load.

• Eliminated flex in heavy graphics card mounts.

• Achieved sleek black finish matching RGB aesthetics.

Key Advantages

✔ Lightweight & Durable – Stronger than plastic, lighter than steel.
✔ Thermal Conductive – Improves heat dissipation in electronics.
✔ Customizable – Threads, lengths, and colors tailored to your needs.
