Standard thread-forming fasteners 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® fasteners 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.
MAG-FORM® Benefits
- Minimizing debris generation
- Forms strong threads in materials with low ductility
- Allows multiple removals and reinsertions, unlike standard fasteners
- Easily removed and reinserted for field service fasteners
- Broad flank angle that compresses, rather than roll-forms threads into the mating material
Standard Design Guidelines
- Available in sizes MG1.0 to MG16
- Wide-spaced thread with broad flank angle
- Can be used with any external or internal head designs
- Can be used with all systems, including TORX®, TORX PLUS®, and TORX PARALOBE™ Drive Systems
- Zinc and Tri-Chrome to minimize galvanic corrosion
Suggested Hole Sizes For Die-Cast Magnesium*
In order to utilize as much available screw strength as possible, the minimum length of thread engagement, excluding the two lead threads, should be equal to 2-1/2 times the basic screw size. Blind holes should be deep enough to allow a two-threaded lead with clearance, at the bottom of the hole. The included draft angle is 1.0°.
