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.
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.
These screws also work well outside the hobby bench, including household repairs, crafts, garage and vehicle work, farm and agricultural equipment, and woodworking projects.
