This achievement is the result of a carefully engineered wedge ramp at the root of the internal thread that only engages when the joint starts to build clamp load during tightening. At that point, the crest of the standard external threads draws tightly against the wedge ramp, eliminating all radial clearance and creating a continuous spiral  line  of contact between the internal and external threads. The outcome is a simple yet effective way to transform a traditional threaded joint into a safer and more reliable design element. Spiralock products solve  fastening issues  in  a variety of applications across  a wide range of industries, including aerospace/defence, electronics, medical, automotive, truck, farm and construction, oil and gas and others.

Using Spiralock self locking threads eliminates the need for spring washers, toothed washers, thread locking sealants, adhesive patches, disk locking washers (Nordlock type), nylon inserts, cotter pins and all other types of thread locking devices.

What is Spiralock?

A self-locking female thread form with a 30 degree wedge ramp at the root of the thread. The wedge ramp allows the bolt to spin freely until clamp load is applied. At that point, the crests of the standard male thread are drawn tightly against the wedge ramp, creating a continuous spiral line of contact along the entire length of the thread engagement.

Superior Fastening Systems with Spiralock

Spiralock creates technologically advanced fastening systems for threaded joint applications that are regularly subjected to heavy vibrations and challenging environments. 

At the forefront of self-locking threaded nut technology, Spiralock fasteners offer great compatibility and consistent reusability. With over 30 years of experience in the industry, Spiralock can be relied upon to prevent critical and demanding threaded joints from failing. 

As Spiralock distributors, Zygology offers a variety of Spiralock fasteners to suit numerous requirements. Whether you need a simple change of fastener or a custom-designed solution, our Spiralock fastening solutions deliver a reliable performance. 

How Do Spiralock Products Work?

Spiralock transformed the standard internal thread profile into a self-locking female thread form by adding a 30° wedge ramp at the root of the thread. This unique design prevents vibration loosening while still allowing external threaded parts to spin freely during assembly. 

The technology behind this unidirectional locking feature offers a simple and effective way to make threaded joints safer and more reliable. By using Spiralock fasteners, you can eliminate the need for toothed washers, spring washers, adhesive patches, and other types of thread-locking devices. 

We’re proud to be Spiralock distributors and offer products that solve fastening issues in applications across different industries. With Spiralock fasteners, you can improve joint integrity and form stable and long-lasting connections in your projects. 

The Main Features of Spiralock Products

At Zygology, our Spiralock products are equipped with various unique features that help you streamline operations. 

Let’s take a closer look at some of the main features of Spiralock fasteners:

Self-Locking Threads

One of the standout features of Spiralock products is the self-locking mechanism, which ensures all fasteners stay secure, even under intense pressure. When you’re working with high-vibration machinery or critical structures, this self-locking feature ensures secure fastening in the most challenging conditions. 

With Spiralock, you can trust that your fasteners won’t loosen, helping improve the safety and reliability of your equipment. 

Vibration Loosening Resistance

Vibration can easily cause traditional fasteners to lose grip, resulting in equipment failure or accidents. 

Spiralock ensures that your fasteners stay secure and helps maintain the integrity of your projects, without constant need for adjustments. 

Effective Load Distribution

Our products offer effective load distribution and allow for the load to be evenly spread across fastener threads. This reduces the stress on individual components and extends the life of your equipment. 

With Spiralock nuts, you can handle high-load applications and challenging jobs securely in the knowledge that they will not fail in critical applications. 

Benefits of Spiralock Products

Our Spiralock fastening solutions are widely recognised for their consistent reliability. Engineered to last, Spiralock fasteners help you achieve your project requirements effortlessly. 

Our Spiralock fasteners offer many benefits, including:

Consistent Fastening Reliability

With Spiralock products, we guarantee consistent fastening solutions that you can rely on. Whether you’re working with heavy loads or in high-vibration environments, when you choose us as your Spiralock distributors, you can be certain that your fasteners will stay secure. 

Our Spiralock products ensure a safe and long-lasting performance in every project. 

Free Spinning

With its free spinning capabilities, Spiralock fasteners make installation faster and easier. Fasteners can turn freely until they reach the locking zone, where it establishes a secure hold. 

Free spinning allows you to reduce friction during installation, prevent thread damage, and simplify the assembly process. 

Improves Joint Fatigue Life

As Spiralock distributors, we understand the importance of joint integrity. One of the biggest advantages of Spiralock fasteners is that they increase the lifespan of your joints and connections. 

With our fastening solutions, you can distribute loads evenly and reduce stress on joints, allowing your projects to run smoothly for a long time. 

Enhanced Operational Efficiency

Our Spiralock fasteners offer secure and reliable fastening with minimal need for maintenance. With their advanced design and self-locking mechanism, they reduce the risk of loosening or failure. 

Being quick to install and designed to last for years, our Spiralock fastening solutions help you complete projects more quickly and effectively.
