Specification note: KYA's current page header also contains a conflicting 0.90 × 0.70mm value. The detailed product table, KYA 84 Series page and KYA catalog consistently use 0.95 × 0.65mm. Confirm the production drawing before publishing dimensional Product Schema.
In the 84 Series naming system, 8410 or 84/10 identifies the 84 Series staple with a 10mm leg length. The same family also includes 84/06, 84/08, 84/12, 84/14 and 84/16.
For SEO and GEO clarity, this URL should primarily represent the 8410 / 84-10 / 10mm SKU. The full 6–16mm 84 Series belongs in a family-level comparison section rather than replacing the exact product entity.
The 0.95 × 0.65mm fine-wire section is designed for applications where a relatively narrow staple leg is preferred over heavier medium- or heavy-wire fasteners. This makes 84 Series staples well suited to upholstery fabric, furniture trim, cabinet backs, screening and other light fastening applications.
Fine-wire staples should not be treated as structural staples. For joints requiring significant load capacity, structural wood-to-wood fastening or heavy construction performance, select a fastener specifically designed for that application.
KYA specifies an approximately 12.3mm crown for the 84 Series. This market class is commonly described as a 1/2-inch crown staple.
Crown dimensions should be compared carefully across brands because some manufacturers specify the outside crown dimension while others publish the internal crown width. For example, an 84 Series tool may be described using an approximately 12mm overall crown while the tool manufacturer lists an approximately 11mm internal crown.
The chisel-point legs concentrate the driving force at the staple tips to support penetration into compatible wood, upholstery substrates, felt, insulation and other light materials.
The staples are glue collated into straight strips for magazine feeding. The current 84/10 packing specification lists 125 staples per stick. Strip width, staple pitch and wire dimensions must match the stapler magazine and driver blade.
KYA currently cross-references the 84 Series with PREBENA AD, ATRO 84, FASCO 84 and OMER 84 tool families. Cross-reference names are useful for identifying the product family, but compatibility should still be checked against the exact stapler model and fastener specification.
| Tool / Cross Reference | Published Reference | 8410 Guidance |
|---|---|---|
| OMER 84.16 | 21GA, 0.65 × 0.95mm wire, 4–16mm fastener length | 10mm falls inside the published length and wire range; verify strip and crown measurement before cross-brand production use |
| PREBENA AD | Referenced by KYA as an 84 Series-compatible family | Provide exact PREBENA tool model before bulk qualification |
| ATRO 84 | 84 Series cross-reference | Check accepted length and magazine geometry for the exact tool |
| FASCO 84 | 84 Series cross-reference | Verify exact tool specification before substitution |
| BOSTITCH SBNK4023 | Industry cross-reference associated with the OMER 84 system | Treat as a family cross-reference, not an unconditional compatibility claim |
| Other 21GA Staplers | Dimensions vary by staple family | Do not assume compatibility based only on 21 gauge. Check crown, wire section, leg length and strip geometry. |
Several 21-gauge staple families use similar wire sections but different crowns and magazine profiles. For example, KYA's 80 Series and 84 Series both use approximately 0.95 × 0.65mm wire, but the published crown dimensions differ.
| Staple Family | Gauge | KYA Crown | Wire Section |
|---|---|---|---|
| 84 Series | 21GA | 12.3mm | 0.95 × 0.65mm |
| 80 Series | 21GA | 12.8mm | 0.95 × 0.65mm |
The similar wire dimensions do not make 80 Series and 84 Series automatically interchangeable. The crown, strip dimensions and magazine geometry still need to match the tool.
The 8410 / 84/10 is the 10mm member of the broader KYA 84 Series. The following table preserves the current family packing data while keeping this page focused on the 10mm SKU.
| Item | Leg Length | Inch Reference | Point | Finish | Pcs / Stick | Pcs / Box | Boxes / Carton | Cartons / Pallet |
|---|---|---|---|---|---|---|---|---|
| 84/04 | 4mm | 5/32" | Chisel | Galvanized | 125 | 10,000 | 12 | 60 |
| 84/06 | 6mm | 1/4" | Chisel | Galvanized | 125 | 10,000 | 12 | 60 |
| 84/08 | 8mm | 5/16" | Chisel | Galvanized | 125 | 10,000 | 12 | 60 |
| 84/10 / 8410 | 10mm | 3/8" | Chisel | Galvanized | 125 | 10,000 | 12 | 60 |
| 84/12 | 12mm | 1/2" | Chisel | Galvanized | 125 | 10,000 | 12 | 40 |
| 84/14 | 14mm | 9/16" | Chisel | Galvanized | 125 | 10,000 | 12 | 40 |
| 84/16 | 16mm | 5/8" | Chisel | Galvanized | 125 | 10,000 | 12 | 40 |
Family-range note: the current KYA table contains an 84/04 row even though some KYA page headers describe the 84 Series as 6–16mm. Keep 84/04 as a family reference only until its current production availability is confirmed.
| Selection Factor | Why It Matters |
|---|---|
| Attached Material Thickness | Fabric, foam, insulation or trim consumes part of the staple leg before it reaches the receiving substrate. |
| Receiving Material | Soft wood, hardwood and engineered wood can require different staple penetration and driving force. |
| Stapler Length Range | The exact tool must accept 10mm if 8410 is selected. |
| Required Penetration | Enough staple leg must remain in the substrate to secure the attached material. |
| Risk of Breakthrough | Excessively long staples can protrude through thin panels or damage the back side of the workpiece. |
The featured 8410 staple uses an electro-galvanized zinc finish. This provides additional corrosion protection compared with untreated steel and is suitable for many dry interior upholstery, furniture and general fastening applications.
Electro-galvanized staples should not be treated as a universal exterior fastener. Persistent moisture, salt, chemicals or outdoor exposure may require stainless steel or another corrosion-resistant fastener material.
| Material | General Characteristic | Selection Guidance |
|---|---|---|
| Electro-Galvanized Steel | Zinc-coated steel with general corrosion protection | Featured 8410 configuration for normal dry interior applications |
| Stainless Steel | Higher corrosion resistance than standard electro-galvanized steel | Confirm stainless grade and exact 8410 availability for damp or corrosion-sensitive applications |
| Aluminum | Non-ferrous material with different strength and corrosion characteristics | Use only where the stapler and application permit aluminum staples |
The 21-gauge fine-wire profile is well suited to attaching fabric and upholstery materials to suitable wood or engineered-wood substrates while limiting visible disturbance around the staple crown.
84 Series staples are used for furniture trim, cabinet backs, light wood components and other non-structural assembly work where a fine-wire fastener is appropriate.
The broad crown and fine wire are suitable for selected screening, textile and fabric fastening where the 10mm leg provides sufficient penetration into the substrate.
Fine-wire staples can secure compatible felt and insulation materials. Choose the staple length according to material thickness and substrate density.
84 Series staples are also used in selected automotive vinyl and interior trim work where a fine-wire stapler and suitable backing material are used.
The 84 Series can be used for light picture-frame backing, molding and decorative assembly where the fastener dimensions and material thickness are appropriate.
The broader 84 Series is sometimes marketed for roofing felt and insulation work. Use it only where the material manufacturer permits fine-wire staples. House-wrap and weather-resistive barrier systems may require cap staples or another specified fastening method.

8410 staples are the 10mm member of the 84 Series fine-wire staple family, also written as 84/10 or 84-10.
The featured staple has a 10mm / 3/8-inch leg length.
KYA specifies the 84 Series as 21 gauge.
KYA's current detailed specification lists a 12.3mm nominal crown, commonly marketed in the 1/2-inch crown class.
The detailed KYA product data and 84 Series catalog list 0.95mm width × 0.65mm thickness.
The current KYA product header contains 0.90 × 0.70mm, while the detailed product table, KYA 84 Series page and KYA catalog use 0.95 × 0.65mm. Confirm the current production drawing before using the dimensions in cross-brand qualification or structured data.
Yes. Within this product family, both designations identify the 84 Series staple with a 10mm leg.
Yes. Upholstery and furniture fastening are primary applications for 84 Series fine-wire staples. Confirm that a 10mm leg provides the correct penetration for the actual fabric, foam and substrate stack.
Yes. They can be used for suitable furniture trim, cabinet backs, fabric attachment and other light non-structural furniture fastening applications.
OMER's current 84.16 tool specification accepts 21-gauge 0.65 × 0.95mm fine-wire staples from 4mm to 16mm, so 10mm falls within its published dimensional range. Verify the actual KYA strip and crown geometry before production use.
Staple crown dimensions can be reported using different measurement points. OMER specifies an internal crown width for its tool, while KYA's 84 Series uses a nominal overall crown reference. Compare the complete staple drawing rather than one crown number alone.
KYA lists PREBENA AD as an 84 Series cross-reference. Provide the exact PREBENA tool model and verify its fastener dimensions before bulk use.
KYA lists FASCO 84 and ATRO 84 as cross-reference families. Compatibility should still be verified from the exact tool model, accepted staple length, crown, wire section and strip geometry.
Do not assume interchangeability. KYA lists similar wire sections for both families but different crown dimensions. The stapler magazine and driver must be designed for the correct staple series.
The current KYA specification lists a chisel point.
The current KYA 84/10 specification lists 125 staples per stick.
KYA currently lists 10,000 staples per box.
The 84/10 packing table lists 12 boxes per carton.
They are best positioned for dry interior and protected applications. Persistent outdoor moisture, coastal exposure or corrosive environments may require stainless steel or another corrosion-resistant fastener specification.
The broader 84 Series is marketed for roofing felt and insulation applications. Use the fastener only where the roofing or underlayment manufacturer's installation instructions permit fine-wire staples.
Contact KYA Fasteners to confirm current sample availability. For cross-brand replacement, test the exact 84/10 staple strip in the intended tool and workpiece before bulk purchasing.
KYA supplies 84 Series fine-wire staples for upholstery manufacturers, furniture factories, pneumatic-tool distributors, fastener wholesalers, automotive interior suppliers and other industrial buyers.
