Mag-Form® fasteners are specifically designed to eliminate tapping operations while forming strong threads in conventional magnesium die castings and similar materials, with minimal debris generation and good serviceability.

Minimizes debris generation in critical applications when driven into low-ductile materials; standard thread-forming fasteners with a 60° flank angle create excess debris. They can easily exceed the ductility limits of the material, causing damage to the formed threads.

Mag-Form® thread-forming fasteners feature a broader flank angle. When driven into low-ductile materials, such as magnesium die-castings, a compressive action forms strong threads in the material with minimal debris generation.

Mag-Form® fasteners also allow multiple removals and reinsertions, unlike standard thread-forming fasteners.

  • Minimum engagement length of full threads is generally 2 to 2 1/2 times the basic screw diameter.
  • Recommended engagement length does not include lead threads (2 pitch ref.).
  • Typical hole engagement: 55%-75% based on application specifics.
