Overview

Standard thread-forming screws with a 60° flank angle create excess debris when driven into low-ductile materials. They can easily exceed the ductility limits of the material, causing damage to the formed threads.

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 air bag modules.

Features

  • Lobular Configuration
  • Wide-spaced thread design
  • Broad flank angle compresses, rather than roll-forms, threads into the mating material

Benefits

  • Minimizes debris generation
  • Forms strong threads in low-ductile materials
  • Easily removed and reinserted for service in the field
