High Light Red Anodized Aluminum Thumb ScrewM3-M5 Aluminum Thumb ScrewHigh Collar Design Aluminum Thumb Screw
Red Anodized Aluminum Thumb Screw – High-Collar Design for PCB Heat Sink Mounting (M3-M5)

Product Overview

Our Red Anodized Aluminum High-Collar Thumb Screw is engineered for secure, tool-free mounting of heat sinks and thermal solutions on printed circuit boards (PCBs). Featuring a lightweight aluminum body, non-conductive anodized finish, and ergonomic high-collar design, this screw ensures reliable thermal management while preventing electrical shorts. Ideal for electronics, IoT devices, and industrial controls requiring efficient heat dissipation and easy maintenance.


Key Features

✅ Anodized Aluminum 6061-T6

  • Non-Conductive Finish: Prevents electrical shorts in high-voltage PCB environments.
  • Corrosion & Wear Resistance: Withstands oxidation and repeated adjustments.

✅ High-Collar Design

  • Spacer Function: Elevates the thumb head above the PCB surface, improving airflow and grip.
  • Ergonomic Grip: Knurled or fluted collar for slip-resistant manual tightening.

✅ Metric Threads (M3–M5)

  • Precision Threads: M3×0.5mm, M4×0.7mm, M5×0.8mm for compatibility with heat sink mounting holes.
  • Thermal Stability: Aluminum’s low thermal resistance minimizes heat transfer to the screw.

✅ Vibrant Red Anodized Finish

  • Aesthetic & Functional: Color-coding for easy identification; enhances corrosion protection.
  • RoHS & REACH Compliant: Safe for electronics and industrial applications.
