Planetary Thread Rolling Dies for Nails
Planetary thread rolling dies for ring-shank and screw-shank nails, made to your machine and thread specification.
Category: Nail Making Tooling
Planetary thread rolling dies put the ring or screw pattern on plain-shank nails after they leave the nail making machine. A set is one rotating rolling ring and the fixed segments mounted around it on the thread rolling machine. Each nail rolls once between the ring and the segments and comes out with its rings or thread formed.
Overview
Overview
We supply sets for ring-shank and screw-shank nails, made to your machine and your thread data, for nail wire from 1.2 to 5.0 mm and nail lengths from 30 to 100 mm.
Ring shank or screw shank: the market decides
Ring-shank nails hold best in softwood and plywood, which makes them the usual choice for pallets and construction. Screw-shank nails turn as they are driven and suit hardwood and other dense materials. The die pattern follows the nails you sell, so tell us which market the nails are for.
Makers use screw, spiral and threaded for different patterns. A drawing or a close-up photo of the nail is the safest way to fix the thread form before the dies are made.
Part of the same nail line
Thread rolling comes after the nail making machine, so a plant that rolls ring or screw nails already runs gripper dies, cutters and punches. Both can go in one enquiry. See Nail making tooling for the full set, and Nail making: tooling by stage for what each stage needs.

Order the segments with the ring
The ring and the segments are made to run against each other. Order them together as one set: segments made on their own may not match a ring that is already in use.

FAQ
FAQ
What is a planetary thread rolling die?
A rotating rolling ring with fixed segments around it. The nail rolls between them once and the ring or screw pattern is formed on the shank. It is the tooling of the nail thread rolling machine, not of the nail making machine.
Should I make ring-shank or screw-shank nails?
It depends on where the nails are used. Ring shank for softwood and plywood, such as pallets and construction; screw shank for hardwood and dense materials. If you are not sure, tell us the market and what the nails are driven into.
What do you need from me to quote planetary dies?
The machine make and model, ring or screw shank, the number of pieces in the set, the thread data, and the nail wire diameter and length. A drawing or a photo of the nail helps.
Which thread rolling machines do you supply dies for?
Prutton, Ingramatic, Omega, Enkotec, Zeus, Ruja, Wafios, Sakamura, Ticho, Salvi and Sima, and others to drawing or sample.
Can I order gripper dies and cutters in the same enquiry?
Yes. Add the nail making machine model and the nail size, and we quote the nail making tooling together with the thread rolling dies.
Can I order segments only?
We recommend ordering the ring and the segments together as one set. Segments made on their own may not match the ring you run.
Which steel should I choose?
Tool steel is the better value for most nail lines: Cr12MoV as standard, with D2 or DC53 on request at a higher price. Tungsten carbide sets can be supplied on request, at a higher price.
What is the lead time?
Usually about 15 days, confirmed by item and quantity when we quote.
