Thread rolling for strong and precise fasteners
In many industrial applications, threads must not only fit precisely but also be able to withstand high loads. That is why Hetraco opts for thread rolling instead of thread cutting. With this technique, the thread is formed by deforming the material rather than removing it, resulting in a stronger thread structure and greater reliability of the fastener.
Hetraco applies this technique on a daily basis in the production of custom fasteners such as bolts, nuts, and studs, manufactured to customer drawings. These components are produced in the company’s own machine shop for customers in industries including equipment manufacturing, petrochemicals, offshore, and the maritime industry.
Specialist in wire rolling
Hetraco has more than twenty years of experience in thread rolling and maintains an extensive fleet of machinery, including several thread rolling machines from the German brand Profiroll. These machines can roll threads in various diameters and lengths. The capabilities range from small diameters to large industrial sizes, allowing for the production of both standard applications and heavy-duty structures. By performing this process in-house, Hetraco can respond quickly when a project requires it.
Why use thread rolling?
Thread rolling is widely used for parts that are subjected to high loads or where reliability is essential. This is because thread rolling involves plastic deformation of the material. The thread is therefore formed without any loss of material. This results in a strong thread structure suitable for heavy-duty industrial applications. Key characteristics of thread rolling include:
- Strong threaded structure resulting from deformation of the material
- Precise dimensions and consistent quality
- Suitable for large diameters and long products
- Applicable to special fasteners as shown in the drawing
Wire rolling for specialty fasteners
Hetraco manufactures specialty fasteners for industrial installations and machinery. These can be standard products compliant with DIN standards, as well as custom-made parts based on customer specifications.
The sizes of products with rolled threads range from approximately M5 to about M200 and are available in various lengths. Many of these components are used in applications where reliability and certification are critical, such as power plants, refineries, and heavy machinery manufacturing.
From Request to Delivery
At Hetraco, a practical approach is key. Each request undergoes a technical evaluation and is tailored to the material, dimensions, and intended use. Production is then scheduled using our in-house machinery, and delivery is arranged as agreed. This process provides customers with clarity regarding scheduling, quality, and delivery.
