# Best Motor Screws for FPV Drones (2026) Source: https://dronefpvlab.com/best/motor-screws Updated: 2026-09-15 Publisher: Drone FPV Lab. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://dronefpvlab.com/how-we-research#our-score Motor screws are tiny but critical, holding your motors to the arms through every punch and hard landing. What matters is correct thread size and length, strong material, and a head type that resists stripping. A screw that is too long can bottom out into the windings and damage the motor, while one too short may not hold, so getting the length right for your motor and frame is essential. This guide suits builders mounting new motors and anyone who has stripped a head mid-repair. Keep a stock of the right sizes, since these small parts get lost and worn easily and you never want a build stalled for lack of one screw. Consider quality steel and a clean drive to avoid cam-out. Match thread and length to your motors and frame, choose durable screws with a solid head, and your motors stay firmly mounted through the roughest flying. ## Picks ### 1. iFlight 150pcs M2 Button Head Hex Socket Cap Screws 10.9 Alloy Steel for Brushless Motors FPV Our score: 8.6/10 (Fit for the job 9/10 · Features and specs 8/10 · Build and materials 9/10 · Value 8/10) iFlight 150pcs M2 button head hex socket cap screws in 10.9 alloy steel, sized for brushless motor mounting on FPV quads.
