Choose a listed size and include it in your enquiry.
Wire width requires a confirmed drawing. Use the crown, gauge and listed leg lengths to begin your enquiry.
Specification notes for ordering
Wire width only: the catalog lists 0.95 mm and .036 in, which are not a resolved unit pair. The crown, wire thickness and six leg-length rows remain separately listed.

APPLICATION EXAMPLES
Where it's used
Explore the materials, joints and workshop tasks below. Match the fastener size and tool to your own workpiece before ordering.
Folded sofa-cover edges
The wider 80-series crown spans folded upholstery fabric at a concealed fixing edge.
Bed-base lining edges
Select leg length for the lining layers and timber backing at the bed-base edge.
Headboard backing covers
Compare crown seating on backed interior coverings before approving the staple length.

8016 Series 21 Gauge Industrial Staples: check the entire cross-section
A familiar series number helps identify a starting point. The crown width, wire width, wire thickness and leg length determine whether a candidate staple matches the tool and joint.
1. Record the crown width and confirm the supplier’s measurement convention on the order drawing.
2. Record both dimensions of the wire cross-section; gauge alone is insufficient.
3. Choose a listed leg length for the material stack and required penetration.
4. Compare the dimensions with the exact stapler model and approve a sample.
Choose for your workpiece and equipment
01
Measure the 80-series geometry
The catalog lists a 21-gauge staple with a 12.9 mm crown and 0.7 mm wire thickness. Wire width requires a confirmed drawing because source labels conflict. Compare the exact tool geometry before treating series names as equivalent.
02
Balance crown and fixing margin
Confirm enough material lies beneath the crown and both legs land in sound backing. Trial edge attachment with realistic covering tension.
03
Check a complete production strip
Assess feeding, strip breakage, seating and covering damage over a representative run. Include the shortest and longest ordered lengths in approval.
Questions before you order
Is an 80-series label enough to replace my current staple?
No. Compare crown width, both wire dimensions and strip shape with the current fastener and tool specification. Confirm the crown measurement convention on the order drawing.
Will the widest crown always retain fabric best?
Selection also depends on weave, tension, edge allowance and backing. Evaluate cut-through and retention on the finished assembly.
Application limits to check
- Do not use a fine-wire covering staple to replace a load-bearing furniture-frame joint.
- Do not assume carton-closing use without the appropriate clinching tool and closure design.
