Heat Sink Screw

A Heat Sink Screw is a functional fastener that combines a screw with a spring structure. It is primarily used for securing CPU heat sinks, thermal modules, and motherboards. The spring provides continuous and appropriate pressure to maintain stable contact between the heat sink and CPU while compensating for assembly tolerances and vibration, helping improve the overall stability of the thermal module.

Maintains Stable Contact Between the CPU and Heat Sink

The spring continuously provides axial pressure to help maintain proper contact between the heat sink and CPU surface, supporting stable operation of the thermal module.

Balances Fastening Pressure

The spring can compensate for variations in height and assembly tolerances, reducing excessive concentration of fastening force at a single mounting point and helping distribute pressure more evenly across the heat sink.

Helps Reduce the Risk of Component Damage

The elastic spring structure helps cushion fastening force and reduces the possibility of deformation caused by over-tightening around the motherboard, CPU area, or heat sink module.

Suitable for High-Volume Heat Sink Module Assembly

By integrating the screw and spring into a single fastening component, the Heat Sink Screw can simplify material preparation and installation procedures, making it suitable for thermal modules used in computers, servers, and other electronic equipment.
