Welcome to our website  

ZāGO Manufacturing Company specializes in producing self-sealing fasteners including seal screws, nuts and bolts for a wide range of industrial and military applications. ZāGO self-sealing fasteners are designed and manufactured with a groove under the head to accommodate a rubber “O” ring which, when compressed, forms a complete seal and permits full metal-to-metal contact.

Through hard work and meticulous attention to the needs of its customers, ZāGO has established itself as a leader in the self-sealing fastener industry. Our customers include major military contractors, aerospace industry suppliers, computer and electronic equipment makers, medical, marine products, and motor vehicle manufacturers. We supply our products to both distributors and Original Equipment Manufacturers (OEMs).

ZāGO prides itself on providing courteous, prompt and precise service to all of our customers. ZāGO is especially adept at providing technical advice to engineers and designers to resolve all types of sealing issues. ZāGO’s fasteners can be found in the most innovative products on the market today guaranteeing high performance in even the most challenging environments. Our products are both ROHS and DFAR compliant.


We invite you to enter our website and discover the wide range of fasteners we offer for all of your sealing needs.



Our philosophy here at ZāGO is that in today’s world the goal should not be to “arrive” but rather to constantly improve our manufacturing processes and products. We will continue to strive to find ways not just to meet our customers’ needs, but to always exceed their expectations.
