Sealing Screws

Delivering You Cutting Edge “O” RIng Technology

ZaGO’s line of self-sealing screws, bolts, and rivets offers you unsurpassable fastening and sealing power. Each of our fasteners is equipped with a unique, malleable and strong captive “O” ring. This device delivers extraordinary results. The “O” ring, which fits tightly and precisely in the groove under the screw/bolt/rivet head, acts as a total deterrent against external/internal contamination from air, water, gas and other materials. As a result, your screws and bolts will perform like never before, granting your most sensitive equipment unbeatable protection with 360 degrees of sealant while achieving metal-to-metal contact.

Our screws and bolts 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 and in any environment which exposes them to a variety of conditions when you use a compatible “O” ring material. Moreover, in the case of high-level vibration, we can fasten self-locking strips, pellets and patches on to your screws or bolts for full shock-absorbency. ZaGO offers clients complete customization–from thread styles to headpiece options to driver types. Your needs are completely met, and your expectations fully exceeded.
