The FSUK-PU & PUH Special range of brass inserts are designed for cold and hot insertion in most Thermoplastics.

Their layered, barbed knurl form enables high pull-out performance in both drilled and moulded holes.


Headed versions offer substantial pull-through performance values.

Shorter versions are available as standard.

Please consult with us for the best type to suit your application.
