Overview

1. Optimizes performance in all types of thermoplastics
2. Provides maximum resistance to back-out and pull-out
3. Minimizes boss failure
4. Increases product reliability

Features

• Narrow 30° thread profile minimizes radial expansion and stress in boss
• Optimum thread pitch allows deeper thread engagement
• Recessed thread root allows optimal material flow
• Round body evenly distributes surface contact between application and screw

Benefits

• Increases load-carrying capability through increased thread engagement
• Can be used in repeat assembly operations
• Provides increased pull-out values
• Optimizes non-reversibility
• Balances load ratio between plastic and screw
• Minimizes installation torque
• Improves clamp load
• Minimizes potential of boss cracking
• Improves load ratio
• Reduces high points of stress on the boss
