Machine Seal Screws

ZaGO’s machine screws are ready-to-use, as they do not require any preparation or clean-up. Our machine screws will continue to exceed your expectations for years on end, as they are reusable and vibration-resistant. Each screw is equipped with a captive “O” ring which is designed to fit various head styles. The “O” ring sealing element acting as a total barrier against external or internal forces such as water, dirt, or air contaminants. In the case of extreme vibration, ZaGO offers self-locking strips, and patches which absorb vibration and protect the integrity of the screw. Build your equipment with our screws, and enjoy superb machine performance for decades.

We offer the following self-sealing Machine Driver Types:

Phillips Seal Screw: Designed by Henry F. Phillips, the Phillips screw is very popular and found in a variety of sizes. In fact, we recommend using this driver type, since it offers excellent control.

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 gives our hardware unsurpassable deterrence against external pressure, vibration and contaminants. Our self-sealing nuts and plugs are ready-to-use and can be installed the same way as their conventional counterparts. They are also and can be used with all surface types. Each one provides sealing power in every direction with metal-to-metal contact. Our collection of Self-sealing nuts includes:

Heavy Hex Sealing Nuts: Only ZaGO delivers you the most heavy duty, and yet easy-to-use heavy hex sealing nut available on the market. Featuring exclusive ZaGO silicon-sealing technology, the heavy hex sealing nut withstands even the most extreme conditions, never caving under the likes of pressure or contamination. Ensure yourself the highest level of security by building your equipment with ZaGO’s heavy hex sealing nuts.

High Crown Acorn Nuts: ZaGO’s high crown acorn sealing nuts serve as a total barrier against damaging forces and substances, thus fortifying your equipment where it is most vulnerable. Build your devices with our high crown acorn sealing nuts—which feature a rubber sealing element—and enjoy high-performance equipment.

Low Crown Acorn Nuts: Military and industry leaders use ZaGO’s low crown acorn sealing nuts to guarantee themselves maximum security. ZaGO’s low crown acorn sealing nuts, which are engineered to feature a rubber inner layer, and safe-keep all your equipment under every circumstance.

Hex Flange Nuts: ZaGO’s hex flange sealing nuts grant you both superb sealing and extra fastening power by extending a built-in washer under the nut where water pressure, gas pressure, dirt, oil and more pose a risk. The rubber element that we have fixed on the inside of our hex flange nut performs the vital task of sealing your off from any harm.

Seal Plugs: Built to resist virtually all aggressive chemical compounds and to withstand extreme pressure and temperature, our seal plugs take fastener security to the next level. We designed them to feature the ZaGO “O” ring which, when compressed, forms an airtight seal about the fastener.

Titanium Screws

Titanium (Ti) is a silver-colored high strength metal. With the highest strength-to-density ratio of any metallic element, titanium is an ideal metal for use in aerospace and military applications. In addition, its high resistance to corrosion also makes Titanium an excellent choice for subsea exploration and other situations where exposure to salt water is a hazard. ZaGO is an acknowledged expert in the fabrication of seal screws from exotic metals and titanium is one of our favorites because of its wide range of utility. Titanium screws are fully resistant to solutions of chlorides, hypochlorites, chlorates, perchlorates and chlorine dioxide. It is an excellent material to prevent seawater corrosion. Because titanium screws can corrosion by seawater up to temperatures as high as 500°F (260°C) as well as survive at ocean depths over a mile below the surface, titanium screws are used throughout the oil & gas, and marine industries. Our collection of titanium screws include:

Socket Cap screws: The 6 flat surfaces within the recess for high torquing without damaging the head and there are no side clearance restrictions making them the ideal choice for assemblies with close tolerances. Socket cap screws are popular due to their space saving design and superior strength.

Slotted Pan Screws: The original screw with a single, elongated slot, was developed centuries ago, and can be found nearly everywhere. It can be used with a  and requires less downward pressure than recessed screws.

Hex Bolts: Titanium bolts are best known for being strong, lightweight and corrosion resistant. Titanium bolts are ideal for applications that require both lightness of weight and excellent strength. Hex bolts have hexagonal heads and machine threads for use with a nut or in a tapped hole.

Hex Nuts: Titanium hex nuts are available in metric or standard sizes and can be manufactured with or without a groove for sealing or non-sealing applications. They are strength but very lightweight.

Custom Machine Parts: ZaGO can provide custom machine parts made-to-print in titanium material. We offer prototypes for testing and also provide secondary and modification processes.

WHOI scientists partner with Rhode Island fishermen to understand rapid changes in Gulf Stream-dominated east coast shelf waters

In 2011, oceanographer Glen Gawarkiewicz sat in the back row at a National Science Foundation (NSF) public hearing about the upcoming installation of a vast and long-term ocean monitoring system, called the Ocean Observatories Initiative Pioneer Array (Pioneer Array). The chosen location, right off the coastal waters of New England, meant the array could interfere with fishing and shipping, and there was concern that the science generated by the array could be used to force fisheries closures. The people whose livelihoods depend on this ocean region were at the hearing and they meant to be heard. “There was a very crowded room in the public library in New Bedford,” recalls Gawarkiewicz, “and there were some contentious moments.” He was sitting next to a woman he hadn’t yet met, and Gawarkiewicz remembers one of them said to the other, “There’s got to be a better way than this.”
