KYA 21 Gauge Galvanized Stitching Wire is identified on the current product page as model 21 Gauge 0.80mm. It is a galvanized steel stitching wire intended for cardboard carton stitching, packaging, bookbinding, booklet making and related print-finishing applications.
For this URL, the key product identity is 21 Gauge + 0.80mm + Galvanized Stitching Wire. The current KYA gauge table identifies 21 Gauge as 0.80mm under German Wire Gauge, while the same nominal 21 Gauge is 0.81mm under ASWG and 0.81mm under BWG. These gauge systems should not be treated as dimensionally identical.
The broader KYA stitching-wire information also lists other diameters, coatings, tensile-strength ranges and spool sizes. Those family-level options are separated below so they are not incorrectly presented as fixed specifications of this 0.80mm SKU.

Wire gauge numbers are not a universal millimeter measurement. The same nominal gauge can correspond to slightly different diameters under German Wire Gauge, ASWG and BWG systems.
For the current KYA 21 Gauge row, German Wire Gauge is 0.80mm, while both ASWG and BWG are 0.81mm. Buyers should therefore specify the required millimeter diameter together with the gauge system when dimensional accuracy is important.
This is particularly important when replacing wire used in an existing stitching head, because machine setup should be matched to actual wire dimensions rather than a gauge number alone.
The featured product on this URL is 21 Gauge 0.80mm round galvanized stitching wire. It should not be confused with the separate 21 × 25 flat stitching wire specification shown elsewhere in the current KYA table.
| Parameter | 21 Gauge 0.80mm | 21 × 25 Flat Wire |
|---|---|---|
| Wire Profile | Round | Flat / rectangular |
| Metric Size | 0.80mm diameter under the KYA German Wire Gauge table | 0.80 × 0.55mm |
| Inch Reference | Use the applicable gauge-system / diameter specification | 0.031 × 0.021" |
| Feet per Pound | 368 ft/lb under the ASWG/BWG 21 Gauge reference | 559 ft/lb |
| Same Product? | No. Round 21 Gauge wire and 21 × 25 flat wire are different wire profiles and dimensions. | |
The following flat-wire table is retained from the original KYA page as a family reference. These dimensions are not specifications of the featured 21 Gauge 0.80mm round-wire SKU.
| Flat Wire Gauge | Size (Inches) | Size (mm) | Feet per Pound | Recommended Thickness |
|---|---|---|---|---|
| 18 × 20 | 0.047 × 0.035 | 1.20 × 0.90 | 221 | 5/8"–2" |
| 19 × 21.5 | 0.041 × 0.030 | 1.05 × 0.75 | 283 | 1/2"–1" |
| 19.5 × 21 | 0.037 × 0.031 | 0.95 × 0.80 | 283 | 1/2"–1" |

| 20 × 25 | 0.035 × 0.021 | 0.90 × 0.55 | 455 | 1/8"–5/8" |
| 21 × 25 | 0.031 × 0.021 | 0.80 × 0.55 | 559 | 1/16"–1/2" |
The current product title and model identify this URL as 21 Gauge Galvanized Stitching Wire. Galvanized is therefore the verified finish for the featured SKU.
The broader KYA stitching-wire description also mentions tin coating. Tin-coated wire should be treated as a separate family option rather than an additional finish automatically included with this galvanized SKU.
The current page does not publish zinc-coating thickness, coating weight, salt-spray duration or another quantified corrosion test for this 21 Gauge 0.80mm product. Those values should therefore be confirmed separately if required by a purchasing specification.
The current KYA product description emphasizes a clean and smooth wire surface, consistent color, absence of visible coating flaking, and wire supplied without kinks or bends. These characteristics are relevant to wire feeding through carton stitchers and print-finishing equipment.
Actual stitching performance also depends on the stitching head, cutter, former, clincher, wire guides, spool setup and machine adjustment. No universal machine-performance or downtime guarantee is stated here.
The current KYA page lists cardboard packaging boxes and cartons as primary applications for stitching wire. The required wire diameter should be matched to the stitching head, carton construction and machine setup.
Bookbinding and booklet making are listed applications for the KYA stitching-wire family. Confirm that the stitching equipment is set for the required 0.80mm round wire before production use.
Side stitching is included in the current KYA application list. Actual material-thickness capacity depends on the stitcher and stitching head rather than the wire gauge alone.
The current product page also lists saddle stitching. Wire diameter and spool configuration should be selected according to the print-finishing machine specification.
Corner stitching and inline stitching are included in the current application references for packaging and printing operations.
The current KYA page publishes a 135,000–165,000 PSI tensile-strength range in its general stitching-wire information. The page does not provide a separate tensile test result or specification specifically identified as the 21 Gauge 0.80mm SKU.
| Data | Scope on Current Page |
|---|---|
| 21 Gauge 0.80mm | Exact model for this URL |
| 135,000–165,000 PSI | Published as general stitching-wire tensile information; not separately identified as a lot-specific or 0.80mm-only tensile specification |
If a purchaser requires a defined tensile range for a particular stitching head or production line, the required tensile specification should be confirmed when requesting a quotation rather than inferred solely from the general family description.
| Parameter | Current Page Information | How It Should Be Used |
|---|---|---|
| Featured Diameter | 0.80mm | Exact model data for this URL |
| 0.40–1.00mm | Broader diameter range described on the current product page | Treat as stitching-wire family range, not as the diameter of this SKU |
| Galvanized | Specified in this product's title | Exact featured finish |
| Tin Coating | Mentioned in the broader product description | Family option; confirm separately if required |
| Round and Flat Formats | Both are described within KYA's stitching-wire range | This URL's 21 Gauge 0.80mm model should remain separate from flat-wire sizes such as 21 × 25 |
The current KYA page describes stitching-wire spool sizes from 2kg to 100kg and specifically lists 2kg, 3.5kg, 10kg, 15kg and 100kg sizes in its FAQ. It also refers to customizable packing.
These spool and packing values are presented on the page at the stitching-wire family level. The page does not confirm that every listed spool size is a standard configuration for the exact 21 Gauge 0.80mm galvanized SKU.
When spool fit is important, confirm the required spool weight, outside diameter, hub dimensions and machine setup during the quotation process.

For purchasing and technical matching, keep the exact 21 Gauge 0.80mm SKU separate from the broader KYA stitching-wire family. The primary product identity for this page is 21 Gauge 0.80mm round galvanized stitching wire.
When replacing an existing stitching wire, provide the actual wire diameter or gauge standard, wire profile, finish, spool specification, stitching-machine or stitching-head model and application. This avoids dimensional errors caused by treating German Wire Gauge, ASWG and BWG as the same standard.
