Right- and left-hand helices
We manufacture dies and rollers for the right- or left-hand thread direction required on the workpiece.

Rollers and Spare Parts
Alongside the rollers that form the thread profile in rolling dies, we manufacture eccentrics, internal tube support mandrels and other die parts. We assess part enquiries using the existing die, a sample or a technical drawing.
PRODUCT AND APPLICATION
Let’s determine the right solution
for your application.
- Roller: the tool that forms the thread profile in the material
- Eccentric: a component used in a thread rolling die
- Internal tube support mandrel: internal support where appropriate
- Custom manufacturing of other die components
To identify the appropriate product, you can share the material type and dimensions, desired thread profile and equipment details. Manufacturing scope and technical suitability are clarified after reviewing your enquiry.

Thread standards
and custom profiles.
We manufacture thread rolling dies and rollers to international thread standards for tubes, screws, bolts and other round workpieces. Alongside common thread families, we also work with custom profiles defined by a technical drawing or sample.
| Thread family / designation | Profile to specify in a manufacturing enquiry |
|---|---|
| Metric M | Coarse- and fine-pitch metric threads. |
| Unified | UNC, UNF and UNEF inch thread series. |
| Whitworth | BSW and BSF thread series. |
| BSP pipe threads | BSPP (G) parallel and BSPT (R) tapered external threads. |
| NPT / NPTF | American tapered pipe thread families. |
| Tr metric trapezoidal | Metric trapezoidal thread profiles. |
| ACME / Stub ACME | Inch ACME and shallower-profile Stub ACME threads. |
| Buttress thread | Asymmetric thread profiles. |
| Round thread / Rd | Thread profiles with rounded crests and roots. |
Single- and multiple-start profiles
Alongside single-start threads, we manufacture to order for two-, three- or more-start thread profiles.
Custom profile from a drawing
We assess different dimensions and pitches of standard threads, or custom profiles, using a technical drawing.
Helix direction and number of starts are specified separately from the thread standard. In your enquiry, please state the thread standard, diameter, pitch, tolerance, right- or left-hand direction, number of starts and any taper. For multiple-start threads, you can also provide the lead.
