Kramer Marine Propellers supplies high-quality propellers in all sizes and materials. Based on the technical data, we can calculate for you which screw is most suitable. Here you can choose from our supply program of standard screws If necessary, a custom-made screw can also be supplied.

Commonly used materials are manganese bronze (MnBr) or nickel aluminum bronze (NiBrAl). NiBrAl screws are commonly used in higher motor power and/or corrosive conditions.

All our screws are checked by us before delivery, re-balanced and fitted with double anti-izing edges.
