b&m-FORM®

Universally usable direct screwing system in all ductile metal materials

In contrast to "trilobular" screws, the b&m-FORM® is designed with a circular cross-section affecting the entire threaded area. The forming zone is also provided with complete and sharply pronounced thread flanks. The geometry of the thread guarantees a secure screwing process even under unfavorable conditions.

  • Diameter: M3-M10
  • Length: depending on diameter / 6 mm - 70 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: 3 - 4 threads
  • Easy hole locating due to the rounded tip shape
  • Circular cross section and complete thread flanks offer maximum flank overlapping and through this a high overtorque
  • Large processing window between tapping and overtorque
  • Easy installation 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
  • Particularly suitable for aluminum direct screwing in cast core holes
  • Suitable for steel and sheet metal applications, zinc and zinc die casting
  • Cover screw connection WAPU / Alu - Die-casting
