ND Patch U.S. Military Parachute Link Threads

ND Industries®, an internationally known developer and supplier of high quality fastener coating products and services, is pleased to announce a new contract to apply ND Patch to fastener threads on parachute links for the United States Military. ND’s Oakland, New Jersey Processing Center is using an application process it developed specifically for this project which provides rapid production, yet eliminates any overspray on this unique fastener.

“Randy (Pachella, ND Production Manager) did a great job designing and building the tooling. When the military engineer came in to review our process, she was very impressed,” said Bill Lang, General Manager of ND’s Oakland, New Jersey facility.

ND is pleased to play a role in making our paratroopers’ equipment as reliable as possible. Adding ND Patch to parachute links ensures that, once the link nut is tightened onto the threads, it will remain locked and secure.

ND Patch meets or exceeds the performance requirements of the following United States Military specifications: MIL-N-25027; MIL-F-18240E; MIL-DTL-18240F.

The ND Patch coating process produces a completely dry product that is fused to the fastener and is ready to use right out of the box. ND Patch performs immediately upon assembly with no curing time required.

The ND Patch material (typically Nylon) is compressed when assembled with a mating part. Its vibration-dampening characteristics create a locking action in the thread instead of at the bearing surface. The resilience of ND Patch holds the fastener in place without adhesives or thread distortion. ND Patch can be repeatedly adjusted and reused.

ND’s patch application process involves no drilling or milling, so there is no loss of the fastener’s strength or hardness and no problematic burrs or chips. Use of ND Patch eliminates the need for costly lock washers, cotter pins, or castellated nuts. It’s also less expensive than applying bottled thread locking compounds at the point of assembly.

ND Industries provides many top quality fastening and assembly related products and services, specializing in threadlockers, sealants, anaerobics, lubricants, adhesives and more, to a wide variety of industries, including military, automotive, electronics, aerospace, marine, construction, and appliance.

ND Patch – Self Locking & Sealing

ND Patch® found its original market in the automotive industry over 40 years ago. This new locking and sealing product quickly expanded into an indispensable service in automotive manufacturing. Currently, ND Patch is a leading fastening technology used, not only in automotive manufacturing, but by a variety of industries in global markets.

A few facts about Patch Technology:

  • Patch is one of the leading technologies used to make fasteners self-locking and self-sealing.
  • Patch coats an average of 90% of the screws in most PC laptops.
  • Patch is regularly utilized on the screws used in bike breaks and gear shifters.
  • 95% of the screws in a giant bicycle are coated with patch.
  • Most mobile phones use about 20 to 25 fasteners, all of which utilize self-locking coatings like patch.

What is Patch?

Patch is an inert fastener coating that makes threaded fasteners self-locking and self sealing. Patch is not a glue. Patch can be applied to almost any threaded fastener by ND Industries®. This pre-application process means that fasteners come to the assembly line ready to use, no adhesives or other locking devices need to be added. The ND Patch, offered by ND Industries, is an advanced nylon/polymer material dryfused to a fastener at the ND® Processing Plant. ND Patch creates a positive lock upon fastener assembly, preventing loosening and leakage at the fastening point. ND Patch applications replace the need for costly lock washers, cotter pins or castellated nuts. Patch technology has, in some cases, also replaced the use of bottled thread-locking compounds. Because ND Patch is pre-applied before assembly, the use of patch coated fasteners instead of bottled products, which are applied during assembly, improves cost efficiency on long runs.

During ND’s Patch coating process the fastener to which the Patch is being applied is heated to a precise temperature. This heating allows a powdered nylon/polymer material to flow into the shape of the fastener thread. Because the ND Patch coating process entails no drilling or milling, the fastener to which ND Patch is applied does not lose any structural strength. ND Patch is typically applied 2 to 3 threads back from the fastener end for easier starting of the nut/bolt assembly. The ND Patch material fuses to the heated fastener instantly upon application. Since ND Patch is not chemically reactive, no cure time is needed. Once the fastener is cooled, ND Patch coated fasteners are ready for use. This means that ND Patch coated fasteners can be immediately put into automatic assembly preparation equipment, saving precious time in the assembly process.

ND Patch can be applied to almost any internally or externally threaded metallic fastener, whether large construction bolts or tiny screws used in portable electronic devices. Moreover, the nylon-like material used in the ND Patch coating process is highly chemical resistant, and will not dry, shrink, or lose its integrity even when exposed to commercial solvents, alcohol, gasoline, motor oil, caustic soda, jet fuel, anti-freeze, brake fluid, and more.

ND Patch is available in standard coverage, 360° Ring Patch – for extra sealing – and Hi-Temp Patch for assemblies that must withstand temperatures up to 500°F (260°C). Developed by ND Industries for assemblies that operate in extreme heat conditions, such as those used in the aerospace, automotive, appliance industries, and others, ND Hi-Temp Patch performs in temperature extremes ranging from -70ºF to +500º F, exceeding the temperature performance of any other high temperature patch application offered by other companies.

How does ND Patch work?

The ND Patch coating works effectively like a spring and a dam. When a ND Patch coated fastener is threaded onto a mating part, the patch material is compressed. Once a patch coated fastener is engaged, the compression of the patch material that occurs during installation exerts a constant spring-like pressure between the fastener and its mate. This pressure, in turn, creates a strong metal-to-metal lock between the fastener and the mating part on the side of the fastener opposite of the patch. Even if the fastener is not fully seated, the pressure of the ND Patch material forms a positive lock, keeping the fastener in place. Once fully seated, ND Patch coated fasteners are resistant to loosening even when subjected to extreme shock impact and prolonged vibration. This resistance greatly reduces the need to retighten fasteners.

The ND Patch material also works as a dam, virtually eliminating the small spaces between the fastener and its mating part and blocking leak paths along the fastener threads. When the fastener is fully seated, the seal created by ND Patch effectively prevents all fluid leakage.

Even though a superior lock and seal are created by the ND Patch coating on a fastener, the presence of the ND Patch material does not affect fastener adjustability. Unlike many bottled thread locking and sealing adhesives, a fastener coated with ND Patch retains service removability. Furthermore, the ND Patch material does not lose its locking power if the fastener is removed. And, since ND Patch is highly resistant to deformation, patch coated fasteners may be repeatedly reused without compromising their locking ability or damaging their threads.

ND Patch is used in the automotive, construction, medical, electronics, and aerospace industries as well as in military applications and many others.

ND Hi-Temp Patch® – Raising the Bar for High Temp Applications

How well can your fastener assemblies take the heat? Do you worry about high temperatures that can cause failure? Do you wonder if there is a fastener application that works beyond 475°F?

The answer is YES – if you’re using ND Hi-Temp Patch®, the latest breakthrough in high temperature patch technology.

Developed by ND Industries® for assemblies that operate in extreme heat conditions, such as those used in the aerospace, automotive, appliance industries, and others, ND Hi-Temp Patch performs in temperature extremes ranging from -70°F to +500°F.

What is a patch?

A patch is a coating applied to a fastener that creates a positive lock, preventing loosening and leakage at the fastening point. One of the more practical benefits of a patch application is that it replaces the need for costly lock washers, cotter pins or castellated nuts. These types of hardware components were the most commonly used methods to prevent fastener slippage before patch technology was available. To improve the cost efficiency on large runs, patch technology has also supplanted the use of bottled thread-locking compounds that require application at the point of assembly.

How is ND Hi-Temp Patch different from traditional patch materials and what are its benefits?

A high temperature patch creates this same kind of lock, with the same resiliency and benefits of a standard nylon patch, but also with the capacity to retain locking reliability at high temperatures. Standard patch may fail to retain functional integrity when exposed to temperatures above 250°F. Most high temperature polyester based patch coatings’ will not endure in temperatures exceeding 400°F. However, as a result of innovative research, ND Industries now offers ND Hi-Temp Patch, a high temperature patch that can withstand temperatures as high as 500°F without compromise to its locking power.

During the patch coating process the fastener to which the patch is being applied is heated to a precise temperature. This heating allows a powdered polymer material to flow into the shape of the fastener thread. During the ND Hi-Temp Patch process the custom formulated polymer material is stabilized to work at extreme high temperatures. It is typically applied 2 to 3 threads back from the fastener end for easier starting of the nut/bolt assembly. ND Hi-Temp Patch is clearly distinguishable from ND Patch®, by virtue its color. ND Hi-Temp Patch is orange or gray, while ND Patch is normally yellow.

The applied coating material fuses to the heated fastener instantly; no curing time is required. Since ND Hi-Temp Patch is not chemically reactive, once the fastener is cooled, it’s ready to use right out of the box. This means that ND Hi-Temp Patch treated fasteners can be immediately fed through automatic feeding equipment, saving precious time in the assembly process. Because the ND Hi-Temp Patch coating process entails no drilling or milling, the fastener to which a patch is applied does not lose any structural strength. ND Hi-Temp Patch coating can be applied to almost any internally or externally threaded metallic fastener, whether large construction bolts or minuscule screws used in portable electronic devices. Moreover, the nylon-like material used in the ND Hi-Temp Patch coating process is highly chemical resistant, and will not dry, shrink, or lose its integrity even when exposed to commercial solvents, alcohol, gasoline, motor oil, caustic soda, jet fuel, anti-freeze, brake fluid, and more.

Overall, the ND Hi-Temp Patch concept is nothing short of genius in its simplicity. The ND Hi-Temp Patch coating, like typical patch, works effectively like a spring or a dam. When a ND Hi-Temp Patch coated fastener is threaded onto a mating part, the patch material is compressed. This is when the sealing action begins. The compression of the patch material exerts a constant spring-like locking pressure between the fastener and its mate, creating a strong metal-to-metal contact. Even if the fastener is not fully seated, the pressure of the patch material forms a positive lock. When the fastener is fully seated, the positive seal created prevents fluid leakage and is resistant to loosening, even when subjected to extreme shock impact and prolonged vibration. This resistance greatly reduces the need to re-tighten fasteners.

Amazingly, even though a superior seal is made by the ND Hi-Temp Patch coating on a fastener, the presence of the ND Hi-Temp Patch material does not affect its adjustability. A fastener treated with ND Hi-Temp Patch retains service removability. Furthermore, the patch material does not lose its locking power if the fastener is removed, and remains extremely impervious to deformation. This ensures that fasteners may be repeatedly reused without compromising their locking ability or damaging their threads.

Coating a fastener with ND Hi-Temp Patch is not only easier and more cost effective than outdated sealing methods, but also ensures fastener reusability and sealing reliability under the strains of extreme environments. So, it would seem the ND Hi-Temp Patch is the best solution for high temperature fastening needs.

ND Hi-Temp Patch is used in the automotive, construction, medical, electronics, and aerospace industries as well as in military applications.
