Thread Rolling
The art and science of Thread Rolling and Knurling
Our sister company excels in the art and science of Thread Rolling and Knurling, two highly effective metal surface treatments offering distinct advantages for a wide range of components. As specialised manufacturing techniques, both processes leverage the principles of cold-forming to achieve superior results compared to traditional cutting methods.

What is Thread Rolling?
Thread Rolling: As previously discussed, thread rolling involves the cold-forming process where specially designed dies press and displace the material to create the thread profile. This process induces a beneficial cold-worked (strain-hardened) effect on the metal, significantly increasing strength and fatigue resistance, while producing no waste material and enabling faster production cycles. It’s the preferred choice for high-quality, durable threads.
What is Knurling?
Knurling: Complementing its thread rolling expertise, our sister company also provides Knurling services. Knurling is a precision surface texturing process that uses hardened steel wheels (or sometimes broaches) to create a specific, repeatable pattern (knurl) onto the surface of a workpiece. This pattern typically consists of fine, crossed ridges or diamonds arranged in a grid pattern.
Key Advantages of Knurling Provided by Our Sister Company:
Enhanced Surface Grip: The primary purpose of knurling is to create a non-slip surface. The textured pattern dramatically increases friction between the component’s surface and whatever is contacting it (e.g., a screwdriver tip, a finger, a tool). This is crucial for parts requiring manual handling, tool access, or user interaction.
• Improved Aesthetics & Identification: Knurling can add a decorative element or a specific pattern to a component’s surface, enhancing its visual appeal or providing a tactile identifier for assembly or quality control purposes.
• Surface Improvement: The knurling process can improve surface finish characteristics by creating a uniform micro-topography, which can be beneficial for subsequent operations like coating application or painting.
• Zero Material Waste: Like thread rolling, knurling is a near-net-shape process. It displaces the surface material rather than removing it, resulting in minimal waste.
• High Efficiency: Knurling is a relatively fast process for creating the desired surface texture, especially when performed on high-volume production lines.
• Precision & Consistency: Our sister company utilises advanced machinery and skilled operators to ensure precise pattern replication and consistent quality across all knurled components, meeting exact specifications.
• Wide Material Compatibility: Knurling can be performed on various metals including steel, aluminum, brass, copper, and titanium, provided the material is sufficiently hardenable or annealed appropriately beforehand.
Applications: Knurling is widely used on components such as handles, knobs, levers, buttons, adjustment rings, tool holders, and parts requiring enhanced tactile feedback or visual distinction.
By leveraging the expertise of our sister company in both Thread Rolling and Knurling, we can offer you fasteners and components featuring threads that are stronger, more durable, and surfaces that offer superior grip or enhanced aesthetics. This partnership allows us to provide comprehensive manufacturing solutions from raw material to finished product, incorporating the best finishing techniques available.
