Heatsink Spring Screw Assembly,CPU Mounting Screw Kit,Cross‑Recess Spring Screw Combination

Product Overview

This CPU heatsink spring screw assembly is designed for reliable installation of desktop CPU coolers on Intel and AMD motherboards. 

The integrated cross‑recess screw and high‑tension stainless steel spring ensure uniform and consistent clamping force under vibration and

 thermal expansion, improving heat transfer efficiency and system stability.

Key Features

Multi‑platform compatible: Fits mainstream CPU sockets including LGA 115x, 1200, 1700, AM4, AM5, and TR4.

Customizable specifications: Thread size, length, spring tension, and dimensions can be tailored to your requirements.

Precision spring tension: Provides stable clamping force to prevent uneven thermal paste degradation.

Corrosion‑resistant: Stainless steel construction with passivated or nickel‑plated finish for oxidation and moisture resistance.

Easy installation: Standard cross‑recess head compatible with common Phillips screwdrivers; no special tools needed.

Why Choose This Assembly

The spring compensates for PCB warpage and heatsink misalignment, ensuring full contact between the CPU IHS and cooler base. 

This reduces thermal resistance and enhances cooling efficiency.
