M3 Cone Washer for FPV Drone Frames
 
The M3 cone washer is a precision-machined, lightweight hardware upgrade designed specifically for FPV drone builds. Engineered to fit standard M3 mounting screws, this cone-style washer enhances both the functionality and aesthetics of 5″ and similar quad frames.
✔ Optimized Fit for Popular FPV Frames — Works seamlessly with high-end frames such as the ImpulseRC Apex and Apex EVO, your own Ruin frame, the Fox-on Blade5, and many others that use M3 fasteners in their assembly.
✔ Improved Load Distribution — The tapered cone shape spreads the clamping force of the screw over a larger surface area, reducing the risk of cracking carbon fiber around screw holes and improving overall structural integrity at critical mounting points. hongniufasteners.en.made-in-china.com
✔ Protection for Carbon Fiber — By acting as a buffer between the screw head and the frame, it helps prevent damage to delicate carbon fiber plates—especially important on top plates, arm clamps, and stack mounts. hongniufasteners.en.made-in-china.com
✔ Stylish Anodized Finish — Typically made from anodized aluminum alloy, cone washers are available in multiple colors. They not only boost durability and corrosion resistance but also add a premium, custom look to your build. Five33
✔ Lightweight & Durable — Constructed from high-grade aluminum, these washers add minimal weight while increasing fastening reliability and longevity in high-vibration FPV environments. hongniufasteners.en.made-in-china.com
