Self-Sealing Nuts

Self Sealing Nuts

Sealing and Fastening Power

When you’re up against harsh environments, ZaGO’s line of self-sealing nuts guarantees you unsurpassable fastening and sealing power. Each of our sealing nuts has been engineered to feature a full 360 degrees of sealed rubber element which grants our hardware unsurpassable deterrence against external pressure, vibration and contaminants. Our Seal Nuts, much like our line of self sealing screws, feature our “O” ring technology. Witness it for yourself: your fasteners will perform like never before, granting your most sensitive equipment unbeatable protection with 360 degrees of sealing power and metal-to-metal contact.

Our self-sealing nuts and plugs are ready-to-use and can be installed the same way as their conventional counterparts. They are also reusable, and can be used with all surface types. Each one provides sealing power in every direction with metal-to-metal contact.

ZaGO sealing products are available in a wide range of screw materials as well as “o” ring material options.
