FAQ
Mining rigs run 24/7 at maximum thermal capacity with extremely powerful, high-RPM fans. The resulting vibration will loosen standard screws, causing the heat sink to detach from the ASIC chip. Our spring screws absorb this vibration and maintain relentless clamping pressure.
Yes. We produce high-strength, precision fasteners designed to handle automotive road shocks, thermal expansion, and the strict anti-corrosion requirements of EV undercarriage environments.
Absolutely. We specialize in solving non-standard fastening challenges and proudly offer rapid 10-day prototyping to help you test clamping forces and thermal efficiency faster.
