b&m-FORM S®
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.
- Diameter: M3 – M6
- Length: depending on diameter / 6mm – 20 mm
- Property class: F10 according to b&m-factory standard WN04/14 or according to DIN/ISO specification
- Flank angle: 60°
- Thread pitch: metric according to DIN 13
- Head geometry: feasible solutions according to customer specification
- Coating: optional according to specification (integrated or additionally applied lubricant according to application)
- Thread forming zone: 1 – 2 threads
- 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
- 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
- Suitable for steel- and sheet metal applications
- Fastening of the sliding roof spring
- Screwing connection of a pump cover
