KYA KYA-C Nail Thread Rolling Machine is an automatic high-speed machine designed to roll screw shank, ring shank, anti-loose and other special profiles onto preformed steel nails. It is suitable for nail manufacturers producing threaded nails for construction, pallets, wooden packaging, furniture, framing and pneumatic collated fastener applications.
The KYA-C processes nails with diameters from 1.8mm to 4.5mm and lengths below 100mm. Its rated production speed is up to 1200 nails per minute, with actual output depending on nail diameter, nail length, thread profile, rolling die configuration, feeding condition and production setup.
The machine uses an electromagnetic vibration feeding system and a pair of rolling dies. The fixed die and reciprocating moving die plastically form the nail shank surface without machining away material. By changing the appropriate rolling dies, manufacturers can produce different screw, ring or specialty shank profiles.

A nail thread rolling machine does not manufacture the complete nail directly from steel wire. It processes preformed loose nails that have already been cut, headed and pointed by a nail making machine.
In the KYA-C, an electromagnetic vibration feeder automatically sorts and delivers the nails to the rolling area. The nail passes between two dies with the required thread profile. One die remains fixed while the other performs a reciprocating movement, pressing and rolling the nail shank so that the steel surface plastically deforms into the required ring or screw pattern.
| Process Step | Function |
|---|---|
| 1. Load Loose Nails | Preformed nails are supplied to the vibration feeding system. |
| 2. Automatic Orientation | The feeder sorts and aligns nails for continuous delivery into the rolling section. |
| 3. Nail Positioning | The nail enters the correct position between the fixed and moving rolling dies. |
| 4. Thread Rolling | Pressure and relative movement plastically form the required ring, screw or specialty profile onto the nail shank. |
| 5. Finished Nail Discharge | Threaded loose nails leave the machine and can proceed to inspection, surface treatment, collating or packing. |
Up to 1200 Nails Per Minute: Designed for high-volume nail shank rolling, with actual production output depending on nail size and rolling profile.
1.8-4.5mm Nail Diameter Range: Supports a broad range of construction, pallet and collated nail sizes.
Up to 100mm Nail Length: Suitable for many common pneumatic and industrial nail specifications.
Electromagnetic Vibration Feeder: Automatically sorts and feeds preformed nails into the rolling section.
Interchangeable Rolling Profiles: Different dies can be used to produce ring shank, screw shank, anti-loose or other specialty nail profiles.
Plastic-Deformation Forming: The shank profile is formed by rolling pressure rather than cutting material away from the nail.
Adjustable Production Speed: Production can be adjusted according to nail dimensions, thread type and line requirements.
Designed for Production-Line Integration: Can be installed between nail making equipment and downstream coil nail, paper tape nail or other collating systems.
| Nail Profile | How KYA-C Is Used |
|---|---|
| Screw Shank Nails | Suitable rolling dies form a spiral or screw-type profile around the preformed nail shank. |
| Ring Shank Nails | Ring-profile dies form annular grooves or rings around the nail shank. |
| Anti-Loose Nails | Special die profiles can be configured to produce specified anti-withdrawal or anti-loose shank patterns. |
| Special-Shaped Nail Shanks | Custom rolling profiles may be possible when suitable tooling is designed for the nail specification. |
| Coil Nail Blanks | KYA-C can roll the shank of loose nails that will later be welded and collated into coil nails. |
| Paper Strip Nail Blanks | Threaded loose nails can subsequently be arranged and bonded into paper strip nails using separate collating equipment. |
The KYA-C is normally a secondary nail-processing machine. It should be positioned after the basic nail forming process and before any required collating or final packaging process.
| Equipment | Function |
|---|---|
| Wire Drawing Machine | Prepares steel wire to the required diameter when raw wire rod must be reduced before nail making. |
| Wire Nail Making Machine | Forms the basic loose nail by straightening, feeding, heading, cutting and pointing the steel wire. |
| KYA-C Thread Rolling Machine | Rolls ring, screw or specialty patterns onto the shank of the preformed nail. |
| Surface Treatment / Polishing | Used where the finished nail specification requires cleaning, polishing or subsequent coating processes. |
| Coil Nail Welding Machine | Arranges and welds loose threaded nails onto wire to form finished coil nails. |
| Paper Tape Nail Collator | Arranges loose nails at the specified angle and bonds them into paper-collated strips. |
| Packing Equipment | Counts and packages finished loose or collated nails for distribution and export. |
Screw shank and ring shank nails require different rolling profiles. Manufacturers should specify the finished nail design when ordering the machine and dies because nail diameter alone is not enough to determine tooling.
| Feature | Screw Shank | Ring Shank |
|---|---|---|
| Profile | Helical / spiral rolling pattern | Annular ring pattern |
| Required Tooling | Screw-profile rolling dies | Ring-profile rolling dies |
| Typical Nail Markets | Pallets, timber packaging, construction and collated nails | Pallets, siding, framing, packaging and other applications requiring increased withdrawal resistance |
| Machine Selection | Confirm nail diameter, length, profile dimensions, rolling length and expected capacity before ordering dies and machine configuration. | |
The rolling dies determine the finished nail shank profile. When ordering a KYA-C machine, provide a finished nail drawing, sample or detailed shank dimensions so the required die profile can be confirmed.
| Information Required | Why It Matters |
|---|---|
| Nail Diameter | Determines whether the nail falls within the 1.8-4.5mm processing range and affects die geometry. |
| Nail Length | Must remain below the supported maximum and affects feeding and handling. |
| Shank Profile | Determines whether screw, ring or another die pattern is required. |
| Rolling Length | Defines how much of the nail shank requires profiling. |
| Pitch / Ring Spacing | Determines the geometry of the finished shank pattern. |
| Finished Nail Sample | Helps confirm tooling when replacing an existing production process. |

Stable thread rolling depends on consistent nail dimensions, correct die adjustment and reliable feeding. Before continuous production, operators should check the feeder track, rolling dies, die gap, nail orientation, lubrication points, drive components and machine fasteners.
Rolling dies are production tooling and should be selected for the target screw or ring profile. Factories producing several nail types should confirm the required spare die sets and changeover procedure when purchasing the machine.
Nail diameter, length, head size and straightness should remain consistent enough for reliable vibration feeding. Poorly formed or heavily deformed incoming nails may affect feeding stability and finished shank consistency.
For accurate machine selection and die configuration, provide the actual nail specification instead of requesting only a generic thread rolling machine price.
