製品の説明
M3 Heatsink Spring Screws, 21mm Overall Length, 7mm Thread, Cross Recessed | Customizable
High-performance M3 heatsink spring screws, 21mm overall length & 7mm thread. Features phosphating surface treatment, ensures perfect mounting pressure & thermal conductivity. Custom specs available.
Our premium Heatsink Spring Screws are engineered to provide consistent and reliable clamping force for critical thermal management applications. The integrated spring mechanism compensates for material expansion/contraction and component height tolerances, ensuring optimal contact pressure between the heatsink and the component (e.g., CPU, GPU, power ICs) over a wide temperature range. This guarantees superior thermal conductivity, long-term stability, and prevents damage to sensitive electronics from over-torquing.

Primary Uses & Applications
These screws are specifically designed for the assembly of cooling solutions in electronic devices where precise and maintained pressure is paramount. Typical applications include:
- Computer Hardware: Securing CPU coolers, GPU coolers, VRM heatsinks, and chipset coolers to motherboards and PCBs.
- Power Electronics: Mounting heatsinks on power transistors, MOSFETs, IGBT modules, and voltage regulators in power supplies and inverters.
- LED Lighting: Assembling high-power LED arrays and modules where efficient heat dissipation is critical for longevity.
- Telecommunications & Server Equipment: Fastening heatsinks in routers, switches, and server blades.
- General Electronics: Any application requiring a sprung load to compensate for tolerance stacks and ensure even thermal interface material (TIM) spread.
How to Use
- Preparation: Ensure the motherboard or PCB has pre-installed brass standoffs (or threaded inserts) with M3 threading matching the screw's specification.
- Alignment: Place the heatsink onto the component, aligning the mounting holes of the heatsink with the threaded standoffs on the PCB.
- Screw Placement: Insert the spring screw through the washer (if applicable), then through the heatsink's mounting hole.
- Initial Threading: Manually start threading the screw into the standoff to avoid cross-threading.
- Tightening: Using a # Phillips screwdriver, tighten the screw until the spring is partially compressed. Crucially, do not overtighten. The goal is to compress the spring to apply the correct force, not to drive the screw until it stops.
- Pattern: Follow a cross or star pattern (e.g., tighten screws diagonally) when installing multiple screws to ensure even pressure distribution and avoid warping the heatsink or PCB.
- Final Check: Ensure all springs are evenly compressed and the heatsink is firmly seated without any wobble.
