REMFORM® II F™ screw
When to choose REMFORM® II F™ screw?
REMFORM® II F™ thread forming screw for plastics is the best solution for the assembly of very hard materials such as glass fiber-reinforced plastics, thermoset materials, phenolic resin,...
REMFORM® II F™ screw is also recommended for the assembly of thermoplastics where the length of engagement is lower than optimal.
How does it work?
- REMFORM® II F™ screws form their own threads into very hard materials.
- REMFORM® II F™ thread employs the Asymmetric thread design of REMFORM® II F™ but increased core diameter and smaller thread pitch, adapted to the assembly requirements of materials with low ductility.
- The smaller pitch of REMFORM® II F™ screws increases the number of threads along the shank of the screws, increasing pull-out and vibrational loosening resistance.
REMFORM® II F™ screw benefits
- The smaller pitch of REMFORM® II F™ thread increases the contact along the shank of the screw, improving pull-out resistance of assemblies on very hard plastics and thermoset materials.
- The low radial forces minimize the risk of overstressing and cracking of the plastic.
- It allows a shorter engagement depth, ensuring an improved clamping force of the assembly.
