REMFORM® II F™ screw for light alloys
When to choose REMFORM® II F™ screw?
REMFORM® II F™ thread forming screws are specially designed for the assembly of Magnesium, Aluminum light alloy and other non-ferrous materials including copper, brass, etc.
REMFORM® II F™ screws are recommended for:
- Magnesium elements with drilled, injected or punched holes.
- Aluminum profiles with open holes.
How does it work?
- REMFORM® II F™ screws form their own threads into untapped holes.
- The smaller pitch of REMFORM® II F™ screws increases pull-out and vibrational loosening resistance.
- The lead threads facilitate alignment into the hole, avoiding the possibility of blockage.
- In applications on Magnesium, the hole diameter may have a wide spread. The design of REMFORM® II F™ screws allows absorbing this variability in the diameter and ensures thread forming in pilot holes with wide tolerance.
Benefits
- Great cost saving opportunities by reducing the operations associated to metric screws.
- Thread design ensures thread forming in pilot holes with a wide tolerance, avoiding blockage and stripping problems.
- Less radial deformation of the housing during thread forming on low ductility materials.
- Low thread forming torque, which provides a more ergonomic assembly.
- High stripping resistance of the assemblies.
- Greater thread engagement, allowing for its use in shallow holes and ensuring greater clamping transmission and pull-out resistance.

Pilot hole diameter guidelines
In order to ensure a safe installation and stable clamping force, it's relevant to pay attention to the pilot hole configuration.
