REMFORM® II HS™
Innovative fastening system for plastics
Plastic: a versatile material
In our increasingly complex world, we can hardly imagine what it would be like without plastics. Nowadays, we come across plastics in use where just a few years ago only metals were to be found. Moreover, the material properties of the latest plastics and state of the art production technologies allow us to implement designs that could not be achieved in metal. With plastics, we can integrate the widest variety of processes and functions into a single component, and manufacture that component in a single production step. However, at some point in the design process, we arrive at the point where the manufactured component needs to be connected to the greater whole. When you designed your component, if you answered "yes" to the questions about whether the fastening needs to be detachable, or whether a defined pre-load force was required, there's no getting round the need for a screw fastening.
Benefits of REMFORM® II HS™
First of all, as it is tapped, the thread in this screw acts as a forming tool, and secondly, it acts as a positive form-locking fastening that prevents the screw from autonomous loosening. The low pitch of the load flank (just 10°) reduces the radial component Frad and, together with the larger thread loading depth, ensures that the screw fastening possesses a high clamping force. With the lower radial strain, the danger of the plastic cracking is reduced to a minimum. Optimised load support in the thread prevents any stress relaxation and protects even further against autonomous loosening.
