Why Choose These Fan Mount Screws?

Fan-Friendly Design: Engineered to install safely without scratching or stressing fan blades or frames — your hardware stays pristine.
Double-Locking Mechanism: The dual-lock nut screw system clamps the fan firmly in place, eliminating any play or looseness that causes vibration and noise.
Quieter Operation: By minimizing micro-vibrations between the fan and chassis, these screws actively reduce operational noise — ideal for home offices, gaming rigs, and media centers.
Enhanced Stability: Solid metal construction keeps your cooling fan running smoothly even under sustained load, preventing fan wobble that can degrade airflow performance.
Space-Saving & Compact: Slim-profile design fits snugly in tight chassis bays where standard screws struggle — perfect for mini-ITX and micro-ATX builds.
Complete Kit Included: Comes with 4 screws, 1 spacer, and 1 installation tool — no extra tools or trips to the hardware store needed.
