Brass countersunk bolts are fasteners with flat heads that sit flush with the surface of the material when fully installed. They are commonly used in woodworking, metalworking, and marine applications due to brass’s corrosion resistance and conductivity .To use Brass Countersunk Bolts, you should first drill a hole in the material to be fastened that fits the screw. This prevents the screw from bending or getting damaged, and it saves time and effort when tightening. Then, use screwdriver to turn the screw in, making sure to keep the turning and pressure steady. Be careful not to let the screwdriver angle shift while driving the screw in, as this can easily damage the screw, cause it to spin endlessly, or even break.
