b&m-REPTO^® BM

Threaded bolt for overmolding in plastics

The b&m-REPTO^® BM is a threaded bolt for overmolding in thermoplastics and thermosetting plastics. The external thread of the bolt, which can be designed both as metric and as customer-specific, can be used for joining and assembling further components. This ensures a process-reliable and repeatable screw connection. The knurl geometry adapted to the overmolding is essential for the later load case.

Depending on the selection of geometry and material, the b&m-REPTO^® BM can be manufactured by machining or completely by cold forming. In the innovative production process using cold forming, the applied material can be used more efficiently and the thread strength can be further increased.

Product features

Diameter: 3mm – 12mm
Length: depending on diameter / thread length adaptable
Material: brass or steel (also available lead-free)
Thread: metric or customer-specific solutions can be produced
Torque absorption: takes place via the knurling designed for the assembly process
Axial force absorption: takes place via additionally applied circular grooves and knurls

Benefits

Customer and application-specific bolt geometries can be produced
Form-fitting connection, for the ideal absorption of torques and axial forces
Process-reliable and repeatable connection
Higher thread strength by cold forming
More efficient production in terms of material and cost, due to constant-volume production process with cold forming
Innovative manufacturing process enables short process times and high output quantities

Areas of use

Unreinforced thermoplastics and thermosets
Reinforced thermoplastics and thermosets with up to 50% glass fiber content

Project examples
