PlasFit Screws

"PlasFit", more commonly known as PT Screws, are 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 torques with high stripping torques.
