The KYA 8016LN Long Nose Upholstery Stapler is a pneumatic fine wire staple gun designed for professional furniture upholstery, automotive interiors, fabric-to-wood fastening, decorative trim and other production applications requiring accurate fastening in narrow or recessed areas.
The tool drives 21 gauge 80 Series fine wire staples with a 1/2 inch / 12.8mm crown in lengths from 1/4 inch to 5/8 inch / 6mm to 16mm. Its extended slim nose improves access around furniture frames, corners, channels and other locations where a standard short-nose upholstery stapler can be difficult to position.

21 gauge fine wire staples create a relatively small penetration mark compared with heavier staple gauges, making the 8016LN suitable for fabric, vinyl, trim and other finished materials where appearance is important.
The approximately 12.8mm / 1/2 inch crown distributes holding force across a relatively wide area, helping secure fabric, vinyl and other flexible materials without concentrating the load at a very narrow point.
The 8016LN uses a durable metal striker designed for repeated professional stapling cycles in furniture and upholstery production environments.
At approximately 1.11kg / 2.45lb, the tool remains relatively light for repetitive upholstery work. The rubber grip also helps improve handling during extended production use.
A relatively straightforward pneumatic construction supports routine inspection and maintenance of seals, driver components and the trigger system.
The 8016LN is designed around the widely used 21 gauge 80 Series fine wire staple format. This staple family is also commonly referenced in the market alongside specifications such as SENCO AT, BeA 80, FASCO 80 and OMER 80. Cross-reference names are useful for sourcing, but actual compatibility should always be confirmed by crown, wire dimensions and staple length.

| Industry Family References | 80 Series / SENCO AT / BeA 80 / FASCO 80 / OMER 80 and equivalent staples with matching dimensions |
KYA's wider 80 Series staple range also includes a 4mm fastener, but the current 8016LN product specification lists 6–16mm as its applicable staple length range. Confirm with KYA before using any size outside the stated tool range.
The 8016LN is designed for attaching fabric, upholstery cloth and related materials to wooden furniture frames used in sofas, chairs, stools, headboards and other upholstered furniture.
The long nose is useful for automotive upholstery and vinyl work where the fastening point may sit inside channels, corners or recessed trim areas.
Fine wire staples are suitable for fastening fabric, cloth and other flexible coverings to suitable wood substrates while helping minimize the visible fastener mark.
The tool can be used for decorative textile installations, trim work and light furniture finishing where precise staple placement is required.
Selected picture-frame backing, furniture trim and light assembly tasks can also use 80 Series fine wire staples where the material thickness and required holding strength are appropriate.
Standard upholstery staplers work efficiently on open, flat workpieces, but furniture construction often includes recessed corners, narrow channels, frame joints and confined areas where the stapler body prevents the nose from reaching the desired fastening point.
A long nose stapler moves the contact and driving point farther away from the main tool body. This provides additional access while allowing the operator to position a staple closer to the required location.
| Application Condition | Long Nose Advantage |
|---|---|
| Deep Furniture Frame | Improved reach into recessed fastening points |
| Narrow Corner | Smaller nose area can improve staple placement access |
| Automotive Trim | Useful around confined vinyl and interior trim locations |
| General Flat Upholstery | Can still perform conventional fine-wire stapling |
A 21 gauge fine wire staple is relatively thin and is commonly used where fabric appearance and reduced material marking are important. Heavier wire staples provide greater cross-sectional strength but create a larger penetration mark and may be unnecessary for light upholstery materials.
| Selection Factor | 21GA Fine Wire Staple | Heavier Staple |
|---|---|---|
| Visible Mark | Smaller | Larger |
| Typical Materials | Fabric, vinyl, trim and light materials | Heavier assemblies and higher-load fastening |
| Typical Upholstery Use | Very common | Application dependent |
Staple length should be selected according to the thickness and compressibility of the upholstery material and the amount of penetration required in the wood or other receiving substrate.
Thin fabric generally requires less staple length than multiple layers of fabric, vinyl or thicker upholstery material. Excessive staple length may increase the risk of breakthrough or unnecessary penetration, while a staple that is too short may provide insufficient holding strength.
| Staple Length | Selection Guidance |
|---|---|
| 6mm / 1/4 in. | Thin fabric and light fastening where limited penetration is required |
| 8–10mm | General fabric, trim and common upholstery work |
| 12–14mm | Thicker fabric stacks and applications requiring more wood penetration |
| 16mm / 5/8 in. | Maximum listed 8016LN staple length for thicker fastening conditions |
These are general selection guidelines rather than fixed rules. Test the chosen staple with the actual fabric, substrate and air pressure before full production.
Use clean regulated compressed air within the specified 70–90 PSI range. Start at the lower end of the operating range and increase pressure only as required to drive the selected staple correctly into the actual work material.
Excessive air pressure can increase component wear and may drive staples too deeply through fabric or upholstery material. Insufficient pressure can leave the staple crown standing above the work surface.
Disconnect the compressed-air supply before loading incorrectly positioned staples, clearing jams, inspecting the driver or performing maintenance.

The 8016LN uses 21 gauge 80 Series fine wire staples with a 1/2 inch / 12.8mm crown. The currently listed tool range is 6mm to 16mm / 1/4 inch to 5/8 inch.
80 Series staples are commonly cross-referenced with SENCO AT and several other fine-wire staple families. However, always confirm crown width, wire dimensions and length rather than relying only on the series name.
BeA 80 is a common industry reference within the 21 gauge 80 Series family. Confirm that the actual staple has the required 12.8mm crown, compatible wire dimensions and a length within the 8016LN's stated range.
A long nose provides better access to recessed furniture frames, narrow corners, channels and other difficult-to-reach fastening points where a standard short-nose tool may not fit easily.
Yes. Furniture upholstery is a primary application for 21 gauge 80 Series fine wire staplers, including fabric-to-wood fastening in sofas, chairs, stools, headboards and other upholstered products.
Yes, the 8016LN can be used for suitable automotive vinyl and interior upholstery fastening where fine wire staples and a long nose provide the required access and holding performance.
The listed operating range is 70–90 PSI. Use regulated compressed air and adjust within this range according to staple length and the material being fastened.
The magazine capacity is approximately 125 staples.
KYA supplies 4mm staples within the wider 80 Series fastener range, but the current 8016LN tool listing specifies 6–16mm. Confirm compatibility with KYA before using 4mm staples in this model.
Possible causes include insufficient air pressure, an air-line restriction, an incompatible staple, a worn seal or driver, inadequate lubrication, or a harder-than-expected substrate. Check the tool within the listed 70–90 PSI operating range and inspect the pneumatic system and fasteners.
Common causes include incorrect staple dimensions, damaged staple strips, debris in the nose, a worn driver, a damaged driver guide or magazine misalignment. Disconnect the air supply before inspecting the fastener path.
Select staple length according to fabric thickness, number of material layers, substrate hardness and required penetration. Use shorter staples for thin material and longer staples only where additional penetration is required.
Provide the required quantity, destination market, air-fitting requirement, staple specification, packaging requirement and any OEM or private-label requirements that need to be confirmed.
Contact KYA Fasteners regarding current sample availability. For production evaluation, test the stapler with the intended 80 Series staple, compressor setup, fabric and substrate before placing a large-volume order.
