Thread Forming Screws for Plastics - PT 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.

Main advantages of using Plasfit:
• Reduced installation torque
• High stripping torque
• Greater safety margin between installation torque and stripping torque
• High parent material shear strength
• Minimises material flow resistance
• Designed to reduce stress within the thermoplastic material
• High resistance to vibration and relaxation
• Allows for smaller bosses
