MINI DIRECT SCREW FIXING
The miniature TMP screw is designed for use in thermoplastics. The design features 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. For applications not requiring the high levels of thread re-use and high clamping torque, TMP screws offer an economical solution to plastics assembly and has distinct advantages over most direct screw fixings.
Advantages :
• Reduced installation torque
• High stripping torque
• Greater safety margin between installation torque and stripping torque
• High parent material shear strength
• Minimizes material flow resistance
• Designed to reduce stress within the thermoplastics to an absolute minimum
• High resistance to vibration and relaxation
• Allows for smaller bosses
