Mag-Form® thread-forming fasteners for magnesium die castings minimize debris generation in critical applications and solve problems often found in standard thread-forming screws.

Standard thread-forming screws with a 60° flank angle create excess debris when driven into low-ductile materials. These standard screws can also exceed material ductility limits, causing damage to the formed threads. Mag-Form® solves these problems.

Mag-Form® screws are specifically designed with a broader flank angle to eliminate tapping operations while forming strong threads in conventional magnesium die-castings and similar materials. The design also minimizes debris, making Mag-Form® fasteners the optimal solution for critical applications such as electronics and airbag modules.

Fast Facts:

  • Lobular configuration
  • Wide-spaced thread design
  • Broad flank angle compresses, rather than roll-forms, threads into the mating material
  • Minimizes debris generation
  • Forms strong threads in materials with low ductility
  • Easily removed and reinserted for field service


  • Sizes: MG1.0 to MG16
  • Thread Design: Wide-spaced thread with broad flank angle
  • Head Design: Can be used with any external or internal head designs
  • Drive System: Can be used with all systems, including the TORX PLUS® Drive System
  • Finish: Zinc and chromate to minimize galvanic corrosion
