Direct screwing system with shortened forming zone suited for all ductile metal materials
The b&m-FORM S® is a conversion of b&m-FORM® with a shortened forming zone. It is particularly suited for screw connections in tight spaces and /or assemblies allowing only a limited protrusion of the screw tip. The fully-formed threads and tip geometry guarantee a reliable screw-in process, even under unfavorable conditions.

Benefits
Due to the short forming zone geometry on the screw thread, it is especially suitable for applications with limited installation space
Circular thread cross section and fully pronounced thread flanks offer maximum flank coverage and through this a high overtorque
Large process window between forming torque and overtorque
Easy assembly with little need for axial force during the screw-in process
A metric thread is generated, so that metric equivalents can be used for repairs
Easy hole locating due to the rounded screw tip
Areas of use
Especially suitable for applications with limited installation space as well as assemblies which allow only minimal protrusion of the screw tip
Suitable for aluminum direct screwing in die-cast or drilled core holes
