Custom Multi-Die Cold Headed Parts


ITW Shakeproof group's multi-die, heading capability extends the traditional limits of cold heading, making possible the production of uniquely formed one-piece cold headed parts. Expensive screw machine parts and multi-piece assemblies can now be economically cold formed as a single piece. Cold forming of parts also improves overall strength and reliability. Among the many features that Shakeproof group can cold form in a heading operation are:

  • Oversize heads
  • Special head configurations — knurled, pancake, etc.
  • Washer heads with oversize washers for spanning and load bearing
  • Large diameter shoulders to replace separate sleeves and collars
  • Multiple diameter or "stepped" shoulders
  • Special pilot or lead points
  • Double-end collar studs
  • Gemini® studs

Design guidance is available to integrate multi-part fasteners into single, cost-effective, one-piece cold headed parts.
