Sealing Fasteners Optimize & Protect Wind Turbines in Any Weather
by Kim Keating
To ensure that water would not enter through the external face cover of the wind turbine and potentially damage the screws or its inner components, Primus Wind Power tapped engineering expert, John R. Marshall Jr., P.E., Owner, Ransford Engineering, to perform a series of water ingress tests. When compared to other fastening options such as washer gaskets, ZAGO sealing screws engineered with a 360° O-ring under the head of the screw successfully prevented water seepage.
