Offered as commercial items as well as MS3212 and MS3213, that meets military requirements. ZAGO’s MS3212/MS3213 parts are time-tested and pressure tested. In fact, ZAGO is the only manufacturer of sealing screws capable of performing NASM pressure testing. We are proud of our ability to meet the exacting needs of our military which in turn enables our customers to support our military in its mission of securing our defense.

ZAGO socket cap seal screws are widely used for their larger head height, resulting in a stronger part, which permits use of a higher torque value. They are engineered with a rubber O-ring under the head of the screw, that once tightened, squeezes outwardly to form a 360° leak-proof seal. This impenetrable, unbreakable seal prevents contaminants, i.e. water, oil, gas, fluids, precipitation, saltwater, dust, moisture and more, from entering and damaging equipment or leaking out and potentially harming our environment.

ZAGO socket cap seal screws have unmatched gripping ability and reduced stripping. Equipment applications include: Air tooling, generators, pumps, compressors, machine parts, automotive components, and electronic devices. Available in corrosion-resistant metals and can withstand extreme pressure, vibration, temperatures (hot & cold) & weather. Made in the USA/Buy American Act compliant.

Socket Button head screws have a socket recess and rounded head. ZAGO’s line of self-sealing screws, bolts, and nuts 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.

An aesthetic fastener which requires less downwards pressure when it is being driven-in. 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.

If your equipment is exposed to high pressure, contamination, or vibration, then protect it with ZAGO’s hex flange sealing nuts. Our hex flange sealing nuts are unique because they are designed with an ingrained rubber element. The power of our sealing technology is unleashed when the nuts are torqued, causing the rubber element within them to form a vacuum-tight seal along the threading of the bolt.
