SPECIFICATIONS
A bugle head screw with a double-lead, consisting of a high and low thread with an extra sharp point and black phosphate finish. The lower thread varies in height from 1/3 to 1/2 that of the higher thread, which is sharper and flatter than a standard thread. Applications/Advantages - Requires less torque to drive than a standard twinfast drywall screw. The high-low thread is more resistant to vibration and reduces the chance of heads popping.
