KYA NR Series Coil Corrugated Fasteners are 12mm crown wood-joint fasteners manufactured from 0.5mm thick steel sheet. Available in NR6, NR8, NR10, NR12 and NR14 sizes, the series covers lengths from 6mm to 14mm for furniture frames, cabinet frames, wood boxes, doors, windows, picture frames and wood repair applications.
The corrugated profile uses alternating grooves to engage the wood across the joint. When driven with compatible equipment, the fastener can reinforce mitre joints, corner joints, butt joints, spliced boards and cracked or split wood while keeping the connection relatively low profile.
KYA lists MA BREVETTI AUT2012 and AUT2000 among compatible tools for the NR Series. Buyers should confirm the exact machine configuration, 12mm fastener width and required fastener length before ordering replacement coils.

For replacement fasteners, confirm the tool model, fastener width, thickness and selected NR length. Corrugated fastening systems from different manufacturers should not be assumed to be interchangeable solely because the fasteners have a similar appearance.
All listed NR Series fasteners use a 12mm width and 0.5mm steel-sheet thickness. The main differences are fastener length and the number of sections supplied on each wheel.
| Model | Length | Inch Reference | Width | Sections / Wheel | Thickness |
|---|---|---|---|---|---|
| NR6 | 6mm | 1/4" | 12mm | 19,200 | 0.5mm |
| NR8 | 8mm | 5/16" | 12mm | 14,400 | 0.5mm |
| NR10 | 10mm | 3/8" | 12mm | 12,000 | 0.5mm |
| NR12 | 12mm | 1/2" | 12mm | 10,000 | 0.5mm |
| NR14 | 14mm | 9/16" | 12mm | 8,000 | 0.5mm |
The NR Series uses a 12mm / 0.472-inch nominal width. The relatively narrow profile is designed for compatible corrugated fastening equipment used in wood-joint assembly and repair.
The alternating corrugations increase the amount of edge contact between the steel fastener and surrounding wood fibers. This helps the fastener grip both sides of a joint and reinforce the connection after installation.
All NR6 through NR14 models listed on this page are manufactured from 0.5mm thick steel sheet. Using a consistent sheet thickness allows buyers to select different penetration lengths while remaining within the same NR product family.
Joint performance depends on wood species, density, moisture content, grain direction, joint design, fastener length and machine setup. Production users should test the selected NR size in the actual material before volume use.
Corrugated fasteners are driven across a joint so the corrugated steel profile penetrates both wood components. The alternating profile grips wood fibers on each side and provides mechanical reinforcement across the joint.
They are commonly used where a low-profile connection is preferred for mitre joints, butt joints, frame corners, spliced boards and selected repair work. The fastener can be positioned on a concealed or less visible face of the assembly when the product design allows.
NR Series fasteners can be used to reinforce mitred and corner-connected components in furniture, cabinet frames, picture frames, wooden boxes, doors and other wood assemblies.
For best results, the joint should be properly aligned and supported before driving the fastener. The selected length must provide useful penetration without being excessive for the thickness of the workpiece.
Select the fastener length according to wood thickness, joint geometry, required penetration and the operating range of the fastening tool. A longer fastener does not automatically provide a better joint if it is unsuitable for the workpiece.
| Selection Point | What to Check |
|---|---|
| Fastener Length | 6mm, 8mm, 10mm, 12mm or 14mm according to the workpiece and joint. |
| Fastener Width | NR Series is listed at 12mm. |
| Steel Thickness | 0.5mm for all listed NR models. |
| Wood Thickness | Select a fastener that provides suitable penetration without passing through the visible face. |
| Wood Species | Test penetration and joint quality in the actual softwood, hardwood or engineered wood being used. |
| Tool Compatibility | Confirm tool model, magazine configuration and accepted NR fastener length. |
| Surface Finish | Choose bright, galvanized or phosphate-coated according to the required service environment and appearance. |
KYA lists the NR Series as compatible with MA BREVETTI AUT2012 and AUT2000 pneumatic equipment.
Before replacing an existing fastener, confirm the exact machine model, magazine specification, 12mm fastener width and supported fastener length. Similar-looking corrugated fasteners from other series may use different widths, collation arrangements or tool systems.
KYA lists bright, galvanized and phosphate-coated surface options for the NR Series.
| Finish | Selection Consideration |
|---|---|
| Bright | Suitable for appropriate dry indoor wood-assembly applications where additional coating is not required. |
| Galvanized | Provides additional corrosion protection compared with an uncoated bright steel surface. |
| Phosphate Coated | Available where a phosphate-treated surface or darker appearance is required. |
For outdoor, high-humidity, chemically exposed or other corrosion-sensitive applications, confirm the required corrosion-resistance specification before selecting a finish.
NR Series fasteners are supplied in high-count wheel formats for repetitive production fastening. The number of sections per wheel decreases as fastener length increases.
| Model | Length | Sections / Wheel |
|---|---|---|
| NR6 | 6mm | 19,200 |
| NR8 | 8mm | 14,400 |
| NR10 | 10mm | 12,000 |
| NR12 | 12mm | 10,000 |
| NR14 | 14mm | 8,000 |
NR Series corrugated fasteners are intended for professional woodworking, production assembly and selected wood-repair operations using compatible fastening equipment.
Corrugated fasteners can be used across selected cracks or splits to provide mechanical reinforcement to damaged wood components such as pallet stringers.
Repair suitability depends on the condition of the timber and the structural requirements of the component. Damaged load-bearing parts should be evaluated before repair, and the fastener should not be used as a substitute for required structural replacement.
Corrugated fastener families use different crown widths, lengths and compatible tools. The NR Series is the 12mm-width option shown on this page. Wider corrugated fastener systems should not be treated as direct replacements unless the fastening tool is designed for them.
| Buyer Check | NR Series Requirement |
|---|---|
| Series | NR |
| Width / Crown | 12mm / 0.472" |
| Thickness | 0.5mm |
| Length | 6mm, 8mm, 10mm, 12mm or 14mm |
| Collation | Wheel / coil format |
| Tool | Confirm exact compatible corrugated fastening machine before purchase. |
