Self sealing fasteners are the screws with nyseal finished. The screws are commonly used in machine parts, die fixturing, and clamping. They are used to fasten machine components, appliances, and more. Under the head sealant (resistant to automotive fluids). Nyseal is a great gasket alternative, creating a gasket-type seal, preventing leakage of fluids and gasses under pressure. The coating is permanently fused on the bearing surface of the fastener. As the screw is seated to its final position against the mating part, the Nyseal element compresses slightly and fills the void between the bearing surface of the head and the countersink/counterbore. Ever Hardware provides custom-made fasteners and customizable packaging.
