Overview
The Du-Bro #4 x 3/4" Button Head Sheet Metal Screws are by far the best way to mount servos, cowls, landing gear, and other components on RC airplanes and surface vehicles. The wide, low-profile button head acts like a built-in washer to spread clamping force, while the internal hex socket gives you positive, no-slip drive engagement.
Bright zinc plated with clear chromate finish for excellent corrosion resistance. Sold as an 8-pack and proudly made in the USA.
