b&m-PLAST R®
Optimized direct screwing system for high-performance plastics
Insufficient load capacity of the connection or fractured bosses: The principle of direct screwing is often difficult to apply in plastic materials. The b&m-PLAST R® is different. As a direct screwing system, it is especially suitable for brittle thermosets as well as for thermoplastics with low reinforcement or high reinforcement (with a glass fiber content of up to 50 %).
Functional principle
The reduced flank angle of 25° minimizes the radial forces acting on the boss. The rounded thread root of the b&m-PLAST R® promotes the homogenous material flow into it. Additionally its increased flank overlap and optimized thread pitch design enable higher tightening torques and preload forces, significantly enhancing process reliability.
Benefits
- Process reliability due to consistent screw-in performance
- No tolerances between screws and self-formed female threads
- High installation speed
- Savings from omitting threaded inserts
- Supports lightweight engineering objectives
