About Us

ZāGO Manufacturing Company has been producing self-sealing fasteners for nearly twenty years and had its origins in the Business Incubator of the New Jersey Institute of Technology, Newark, New Jersey. Five years after its founding ZāGO graduated from the Incubator with a special achievement award and moved to the Ironbound district of Newark where its business flourished. In 2005, ZāGO moved its operations to a state-of-the-art facility in south Newark in close proximity to Newark Airport, the Port of Newark and all of  New Jersey’s major transportation routes.

ZāGO maintains its administration systems in accordance with the standards and guidelines of ISO 9001:2008. Accordingly, ZāGO has been accessed and approved by QAS-International and is the holder of certificate No. A2704US.

ZāGO is proud to manufacture its products in the U.S.A. using the best materials available.

Seal screws are unique in their head configuration.  As you can see from the illustration, a recess groove is machined or cold-headed to form a cavity shape into which the "O"-ring is fitted.  The groove volume is calculated based on the "O"-ring cross section, the "O"-ring inside diameter and the compression of the cavity walls, i.e., the groove into which the "O"-ring is fitted.  The combination of the cavity (groove) and the "O"-ring provides a tight seal by squeezing the "O"-ring.  In the illustration you can clearly see that with the "O"-ring compressed, a zero clearance is created within the cavity itself, blocking the internal/external flow of liquids or gases.

At Zago, each feature of each screw is tested to eliminate any and all sources of seal screw failure.
