Description: HeadStyle-Recess-Thread-Length-Plating  e.g PD1411-KA22-5-Z

The PD Screw is a direct screw fastener for use in thermoplastics. The key design aspects include a profiled thread root to assist plastic flow, a 30° flank angle to reduce boss bursting forces, and an 8° pitch angle - which combine to give low installation torque - with high stripping torques.
