DU-BRO #4 x 1/2" button head sheet metal screws (item 527) are general-purpose fasteners for R/C aircraft builders and hobbyists who need a clean, secure hold when mounting servos, cowls, landing gear, and similar hardware.
Why Modelers Use These Screws
The wide, low-profile head acts as its own washer and spreads clamping force over a larger area. A socket head gives you no-slip driver engagement during installation and removal.
