The C-760A uses the established 16 gauge 1/2-inch inner-crown C-ring format. Compatible rings have an approximately 12.5mm inner crown, 16.9mm outer crown, 8.5–8.7mm height and 1.6mm wire diameter.
This fastener geometry is commonly sold under references including 516G100, SC660 and C17. Naming varies by supplier, so buyers should compare the physical dimensions rather than relying on the series name alone.
The same ring may be described as a 1/2-inch crown or a 16.9mm crown depending on whether the manufacturer quotes the inner or outer dimension.
Approximately 12.5mm / 1/2 inch is the inner open crown, while approximately 16.9mm / 5/8 inch is the outside crown. Checking both dimensions helps avoid confusion with larger 15 gauge C-ring systems.
Compatible C-rings use approximately 1.6mm wire. This is an important distinction from common 15 gauge upholstery C-rings, which typically use approximately 1.8mm wire and a larger crown.
An incorrect wire diameter can affect magazine feeding, jaw clearance and finished ring geometry even if the open crown looks similar.
KYA lists the C-760A with an approximately 3.0–4.8mm finished closure range. The required final diameter depends on the ring, jaw geometry and the wire, fabric or other components being fastened.
Different tools within the broader 516 Series can form different finished closures. For example, some tight-closure tools form approximately 1/8-inch rings, while other versions form approximately 3/16-inch closures.
For production use, test the selected C-ring with the actual material bundle and confirm that the finished ring provides adequate retention without excessive crushing or deformation.
The C-760A holds approximately 100 compatible collated C-rings. This supports repetitive upholstery, cage and mattress assembly while keeping the tool compact enough for manual positioning.
Use correctly collated rings and avoid loading distorted strips. Damaged collation or incorrect fastener dimensions can cause feeding problems.
At approximately 1.5kg, the C-760A is comparable in weight to other industrial 16 gauge pneumatic C-ring tools in the same size class.
The balanced body and rubber grip are intended to improve handling during repetitive fastening. Operator comfort still depends on work height, hose routing, production rate and shift duration.
KYA specifies a high-strength alloy steel muzzle for the C-760A. The muzzle and closing jaws guide the C-ring and determine its final form during each fastening cycle.
Jaw wear, contamination or misalignment can change the finished closure. Inspect these components regularly when the tool is used in high-volume production.
KYA lists an operating pressure of approximately 70–120 PSI / 5–8.3 bar for the C-760A and a 1/4-inch NPT air inlet.
Use clean, regulated compressed air and start with the lowest pressure that produces the required closure. Increasing pressure should not be used to compensate for incorrect rings, worn jaws or poor feed alignment.
Automotive seating is a common application for pneumatic C-ring tools. The C-760A can be used to fasten compatible listing wire, frame wire, upholstery components and other seat assemblies where the 16GA C-ring geometry is appropriate.
The required closure should be tested on the actual seat construction because component diameter and material thickness vary between seat designs.
The tool can be used in compatible spring mattress and bedding assemblies to connect wire, border components and related mattress hardware.
Do not assume that every mattress spring system uses the same C-ring. Confirm spring wire diameter, joint geometry and required closure before establishing production settings.
The 16GA 516 / C17 ring class is widely used for pet cages, animal enclosures, traps, wire mesh and related fabrication where the closed ring fits the joined wires.
For outdoor cages or mesh, select galvanized, Galfan, stainless steel or another specified ring material according to the corrosion environment.
C-rings can be used for compatible fencing, netting and mesh connections where the 16.9mm outer crown and finished closure provide the required fit.
For load-sensitive or specification-controlled fencing systems, confirm the fastener material, ring spacing and connection requirements before use.
The C-760A can also be used for selected bag closure, mesh bag and industrial binding applications where the material bundle fits inside the closed ring.
Sharp or blunt-point fasteners should be selected according to whether the ring needs to penetrate fabric or simply close around the components.
| Reference | Typical Specification | Guidance |
|---|---|---|
| 516G100 | 16GA, 1/2" inner crown, approx. 16.9mm outer crown | Established 516 Series fastener reference for this tool class. |
| SC660 | 16GA C-ring class | Legacy/common market reference associated with 516-format tools. |
