WR^®-TriTite 300

A new developed WR^® screw solution for usage in metal material
A thread rolling trilobular configuration forms thread in drilled, punched or cored holes in metal material. Due to the self threaded shank the resistance to vibration loosening is improved. The application of our WR^®-TriTite^® reduces your assembling costs and expensive tapping operations are not longer necessary. The trilobular shape reduces friction and the driving torque.

Benefits:

• Trilobular configuration
• 60° thread angle
• Resist vibration loosening
• Removal of inefficient operations
• Chipless metal forming
• Consistent thread profile
• Generates strong mating thread
• Maintains joint integrity
• Lower driving torque
• Improves assembly operations
• Easy replacement with machine screws
• Removal and reinsertion of fasteners are possible
• Material:
  • Steel: grade 10.9 or acc. to DIN ISO 7500
