About Kramer Screws

Kramer Screws repairs and supplies propellers from 20 cm to 2 meters for pleasure and commercial vessels.

An incorrect or damaged propeller leads to increased fuel consumption, reduced performance, vibration, noise and/or consequential damage. So it is very important that your screw is the right one.

Because we are the only screw repair company in the Netherlands to use the MRI, an advanced 3D measurement method, your screw is not only demonstrably customized, but also finished faster.
