b&m-FORM LG® Vario
Universal direct screwing system for different materials
The b&m-FORM LG® Vario is ideal for direct screwing into light alloys such as aluminum, magnesium, and zinc, as well as thermoplastic and thermoset plastics. It combines the functions of multiple threaded fastening systems, making the b&m-FORM LG® Vario an intelligent solution for standardizing.
Functional principle
Compared to the 60° flank angle of a metric thread, the b&m-FORM LG® Vario features an asymmetrical thread. The 80° flank angle – with 30° on the load side and 50° on the opposite side – creates a high level of self-locking, preventing the screw from loosening due to possible relaxation of the clamped component. Additionally, the larger thread pitch results in shorter process times during screw-in process.
Threaded connections in light alloy castings and plastics are possible with high preload forces.
Benefits
- Combines the benefits of direct screwing in plastics and metals
- The integrated dog point geometry improves the assembly performance
- Faster screw-in process due to larger pitch compared to metric threads – for shorter process times
- Standardization of the parts variety possible
