RZB MS
Knurled washers for pre-assembled screws RZB MS can provide an excellent screw clumping, thanks to their particular conical shape with milling on both bearing surfaces.
The washer must be inserted into the screw before the thread rolling process in order to avoid any possible loss of the washer itself and allow its rotation when screwing.
Knurled washers type RZB MS can be produced and supplied only upon customer's request.
