Offshore Wind

Malfunction is Not an Option.
Engineers & OEMs In Offshore Wind Choose ZAGO Sealing Fasteners Engineered with 360° O-Ring Technology.

As the world transitions from fossil fuels to renewable energy, offshore wind power is leading the charge as a viable alternative. Generating continuous offshore wind power means that offshore wind turbines, their electrical components, and sensors transmitting real-time sensitive data, must run seamlessly.

Failure Is Not an Option

Engineers designing and OEMs producing offshore wind turbines, blades, sensors, and inner components choose ZAGO corrosion-resistant sealing fasteners for their unique ability to seal equipment without breakage, rusting or leakage – in harsh weather, salty oceanwater and air, extreme temperatures (hot & cold), torrential rains, hurricanes, tropical storms, snow and high winds repeatedly and over long periods of time.

The ZAGO Difference – Screw and O-Ring Engineered as One

ZAGO sealing fasteners are engineered with a custom groove underneath the head of the screw. When combined with a rubber O-ring and tightened, the O-ring squeezes outwardly to form a 360° leak-proof seal. The seal will not break or crack once the screw is torqued preventing seepage or leakage of contaminants, i.e., sand, water, moisture/humidity, dirt, from entering sensitive equipment and damaging it or leaking out and potentially harming our environment.
