Self-Sealing Fastener Products

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.

Groove Radius

Seal screws are considered effortless, dependable & cost-effective because:

  1. Seal screws are capable of bi-directional sealing;

  2. Seal screws can compensate for tolerance run-out;

  3. Seal screws are re-useable (within limits);

  4. Seal screws are resilient, hence no re-tightening is required;

  5. Seal screws require no special installation tools or primers;

  6. Seal screws project a small sealing footprint which enhances sealing properties;

  7. Seal screw circular cross-section symmetry allows for sealing in all directions (radially, axially or angularly); and

  8. Seal screws are made of compounds that can resist virtually all aggressive chemical & environmental applications.
