KYA M87 clinching clips are heavy-duty galvanized steel strip fasteners designed for compatible pneumatic clinching tools used in furniture spring assembly, automotive seating, mattress and wire-frame manufacturing, cages and selected industrial wire applications.
The current KYA M87 family includes CL-31, CL-33, CL-37 and CL-39. These clips share an approximately 11 mm crown and nominal 1.5 mm material thickness, while the inside opening and clip height vary by model to suit different wire combinations and finished clinch geometries.
Because M87-style clinching systems can use different magazines, blades and anvils, select the exact clip according to the tool configuration and wire dimensions rather than relying only on the M87 series name.
Heavy-duty M87 series: strip-fed clips for compatible industrial pneumatic clinching tools.
11 mm crown: compact A-profile width used for compatible wire and spring connections.
1.5 mm nominal thickness: heavier material than many lighter mattress and furniture clip families.
Multiple openings: 7.2 mm and 9.6 mm inside-width options for different wire combinations.
12–19 mm heights: multiple open clip heights for different joint geometries.
Galvanized steel: zinc-coated surface for corrosion protection during storage, manufacturing and appropriate service conditions.
Strip-fed collation: designed for compatible M87-style clip tools and clinching equipment.
Industrial applications: furniture springs, car-seat frames, mattresses, cages and selected wire assemblies.
| Model | Crown | Inside Width | Height | Thickness | Packing |
|---|---|---|---|---|---|
| CL-31 | 11.0 mm | 7.2 mm | 12.0 mm | 1.5 mm | 10,000 pcs / carton |
| CL-33 | 11.0 mm | 9.6 mm | 13.0 mm | 1.5 mm | 10,000 pcs / carton |
| CL-37 | 11.0 mm | 9.6 mm | 17.0 mm | 1.5 mm | 10,000 pcs / carton |
| CL-39 / 132A38 Reference | 11.0 mm | 9.6 mm | 19.0 mm | 1.5 mm | 6,000 pcs / carton |
The correct M87 clip should be selected from the actual wire combination and the required closed joint. The crown, inside opening, height and material thickness all affect how the open clip positions around the components and how it forms against the clinching anvil.
| Dimension | Selection Consideration |
|---|---|
| 11 mm Crown | Must match the tool magazine, blade and anvil profile. |
| 7.2 / 9.6 mm Inside Width | Determines the available opening for the wires or components before closure. |
| 12–19 mm Height | Changes the amount of material available for forming around the joint. |
| 1.5 mm Thickness | Requires a compatible heavy-duty clinching-tool configuration. |
The KYA M87 family shown on this page uses a nominal 1.5 mm steel thickness. This makes the series a heavier clinching format than many lighter furniture and mattress clip families.
A thicker clip does not automatically mean a stronger finished joint in every application. Joint performance also depends on clip geometry, material properties, wire diameters, tool adjustment, anvil profile and the final closed shape.
The featured M87 clips use a galvanized steel surface. The zinc coating provides corrosion protection compared with uncoated carbon steel during storage, manufacturing and suitable service environments.
For continuously wet, coastal, chemically aggressive or other demanding environments, specify the required material and coating rather than assuming a standard galvanized clip is suitable for every exposure condition.
CL-31, CL-33, CL-37 and CL-39 are supplied as collated strip clips for compatible clinching tools. The strip is advanced through the magazine so each open clip can be positioned around the selected wire connection and formed by the tool.
Tool compatibility depends on more than the M87 name. The magazine, guide, blade and anvil must be configured for the selected CL model.
M87-style clinching clips are used in compatible upholstered-furniture assemblies to connect support wire, paper-wrapped wire or other wire components to springs and seating frames.
Typical applications include sofa backs, sofa bases, chairs and other furniture spring systems. The clip size should be selected according to the actual spring-wire and support-wire diameters.
Heavy clinching clips are also used in compatible automotive seating and formed-wire assemblies where spring wire or support wire must be mechanically joined to another wire component.
Automotive components normally follow application-specific drawings and production requirements. Confirm the exact clip size, material, closing profile and tool configuration before using an M87 clip in production.
M87 clinching clips can be used in compatible mattress and spring assemblies where larger wire combinations require a heavier strip clip than smaller M46- or M66-type systems.
The correct model depends on the spring wire, border wire, stay wire or frame-wire combination and the required finished closure.
M87-style clips are also used in compatible wire-cage and mesh fabrication where adjacent wire components require a mechanically clinched connection.
Select the clip from the actual wire diameters and finished joint geometry. Different cage and mesh products can require different openings and clip heights.
Certain M87-series heavy clinching clips are used in compatible industrial razor-wire assembly equipment. CL-35, CL-37 and CL-39 are among the sizes commonly associated with M87-style clipping tools used for wire-barrier production.
The exact clip must match the production machine, strip feed, blade and anvil. Do not assume every M87 clip model on this page is suitable for the same wire-barrier equipment.
KYA identifies CL-39 with the 132A38 reference. CL-39 uses an approximately 11 mm crown, 9.6 mm inside opening and 19 mm height.
Vertex also publishes 132A38-series strip clips with a nominal 1.32" length, 7/16" width and .38" opening. The width and opening correspond closely to the CL-39 dimensional class.
| Parameter | KYA CL-39 | 132A38 Reference |
|---|---|---|
| Crown / Width | 11.0 mm | 7/16" / approximately 11.1 mm |
| Inside Opening | 9.6 mm | .38" / approximately 9.65 mm |
| Open Height | 19.0 mm | Confirm by manufacturer drawing and tooling |
| Feed Format | Strip | Strip |
Use 132A38 as a cross-reference for product identification and dimensional comparison. Confirm the full clip geometry, collation and tool configuration before cross-brand substitution.
KYA publishes an M87 pneumatic clinching-tool platform for selected heavy strip clips including models such as CL-33, CL-35, CL-37 and CL-39, depending on the tool configuration.
Different CL sizes may require a different internal setup. When ordering clips for an existing M87 tool, provide the exact clip currently used or the machine's blade, anvil and magazine specification.
M87 is used commercially for a family of heavy clinching clips and tools, but different suppliers publish variations in clip dimensions, material thickness and accepted fastener models.
For this reason, a clip should not be selected only because both the fastener and tool are described as M87. Compare crown width, inside opening, clip height, material thickness, strip collation and tooling before use.
| Model | Inside Width | Height | General Selection Consideration |
|---|---|---|---|
| CL-31 | 7.2 mm | 12 mm | Smaller inside opening and lower profile for compatible smaller wire combinations. |
| CL-33 | 9.6 mm | 13 mm | Wider opening with a relatively short open clip height. |
| CL-37 | 9.6 mm | 17 mm | Same nominal opening as CL-33 with additional forming height for different joint geometry. |
| CL-39 | 9.6 mm | 19 mm | Tallest listed KYA M87 clip on this page; similar dimensional class to 132A38. |
| Model | Current KYA Packing |
|---|---|
| CL-31 | 10,000 pcs / carton |
| CL-33 | 10,000 pcs / carton |
| CL-37 | 10,000 pcs / carton |
| CL-39 | 6,000 pcs / carton |
Packing differs by clip size. Buyers should specify the required CL model rather than assuming every M87 clip is packed 10,000 pieces per carton.
Start with the diameters of the components being joined and the existing tool configuration. The open clip must fit over the wire combination, while the blade and anvil must close the clip to the required finished geometry.
If an existing production line is already running another clip, provide the current fastener model, physical sample or drawing when requesting a replacement.
