KYA M88 Mattress Clinch Clips are galvanized steel fastening clips designed to connect stay wire, paper-wrapped wire and compatible spring components in mattress, sofa, upholstered furniture and automotive-seat production. The M88 family uses a 0.90mm clip thickness and includes multiple crown, inside-width and height configurations for different wire and spring assemblies.
The current KYA M88 range includes M88, M88-1, M88-2 and M88-3. Published crown dimensions range from 21.8mm to 32mm, with inside widths of 8.5mm or 9.5mm depending on the model. Standard published packing is 6,000 clips per carton.
M88 clips can be installed using suitable pliers or compatible clinch-clip tools. Tool selection should be based on the exact clip model, open clip dimensions, wire combination, collation format and required closed-clinch geometry rather than the M88 name alone.

Cross-reference note: KYA currently identifies M88-1 as similar to 135H31. Treat this as a starting reference rather than an unconditional interchangeable-part claim. Confirm the complete open-clip dimensions, collation, tool and required closed-clinch geometry before replacing another manufacturer's clip.
An M88 clip is a formed metal clinch fastener used to join compatible wire and spring components. The open clip is positioned around the wire combination and then mechanically closed so the clip wraps around and retains the components.
In mattress and furniture production, this type of clip is commonly used where stay wire, paper-wrapped wire or another support wire must be attached to springs or wire frames. The correct clip must be large enough to fit around the components before closure while producing the required finished clinch after installation.
| Selection Parameter | Why It Matters |
|---|---|
| Crown | The M88 family includes published crown dimensions from 21.8mm to 32mm, so model selection cannot be made from the M88 name alone. |
| Inside Width | The opening must accommodate the intended wire or spring combination before clinching. |
| Clip Height | Height affects the open clip envelope and final closing geometry. |
| Wire Diameters | Provide the diameter of each wire or spring component being connected. |
| Closed Clinch | The finished clip must secure the components without being excessively loose or crushing the wire assembly. |
| Tool Model | Driver, magazine and anvil geometry must match the exact clip configuration. |
| Collation | Confirm whether the production setup requires strip, roll or another specified clip feed format. |
| Environment | Select EG, HDG or another specified material according to the corrosion exposure and application requirements. |
The current KYA M88 table lists M88-1 as similar to 135H31. “Similar” should not be interpreted as an automatic one-for-one replacement because clip naming systems can use different measurement conventions, collation formats, packing quantities and tool references.
If you currently use a 135H31, 135H31S or another Hartco / Vertex-style clip, provide the existing clip number, actual dimensions and tool model. KYA can then compare the required M88 geometry before bulk use.
| Collation Format | General Use | What to Confirm |
|---|---|---|
| Strip Clips | Used with compatible strip-fed clinch tools or suitable manual/pneumatic equipment | Strip length, clip spacing, clip dimensions, magazine and anvil |
| Roll / Polycord Clips | Used in compatible continuous or roll-fed production systems | Roll configuration, clip spacing, feed system, tool model and current production setup |
| Loose Clips | Used only where the installation tool or manual process is designed for loose clips | Confirm loose-clip availability for the exact M88 model before ordering |
The current KYA M88 page lists strip and roll / polycord within the family. Do not assume every M88, M88-1, M88-2 and M88-3 configuration is available in every collation format without current production confirmation.
| Finish | General Selection Guidance |
|---|---|
| Electro-Galvanized (EG) | Zinc-coated steel option for many furniture, bedding and protected industrial applications; exact coating specification should be confirmed where corrosion performance is critical. |
| Hot-Dip Galvanized (HDG) | Heavier galvanized finish option where the application requires greater corrosion protection and the clip/tool configuration supports the coating. |
The current M88 page does not publish coating thickness or a verified salt-spray test duration. Do not assign a specific corrosion-hour rating unless the production specification or test report supports it.
M88 clips can connect compatible stay wire or reinforcing wire to spring components in mattress production. Select the clip according to the wire diameters, spring geometry and required closed-clinch dimensions.
Furniture manufacturers can use clinch clips to join suitable support wire to spring assemblies in sofa bases, sofa backs and other upholstered furniture structures.
The current M88 application data includes car seats and automotive seating. For production automotive use, the exact clip dimensions, material, finish and fastening process should match the assembly specification.
Selected M88 configurations are also marketed for wire cages and netting. Wire diameter and exposure conditions should be provided when selecting the clip and galvanized finish.
M88 clips may be used when repairing compatible spring and stay-wire assemblies. For replacement work, compare the removed clip's dimensions rather than ordering only by visual appearance.
Measure the stay wire, spring wire or other components that must be joined. The open clip must fit around the complete wire combination.
Compare the required opening with the M88, M88-1, M88-2 and M88-3 crown, inside-width and height dimensions.
Place the clip around the wire and spring at the intended joint position. Keep the components correctly aligned before closing the clip.
Use pliers or a clinch tool whose driver and anvil are designed for the exact clip. The tool forms the clip around the wire combination during closure.
Check that the clip is fully seated, the wire components remain correctly positioned and the clip has not cut, crushed or excessively deformed the joined wire.
The current KYA M88 page states that the clips can be installed using pliers or clip tools but does not identify one verified pneumatic tool model for every M88 variant. For that reason, this page should not claim universal compatibility with all Hartco, Vertex, Encore or other clinch-clip tools.

M88 clips are metal clinch fasteners used to join compatible spring, stay-wire and wire-frame components in mattress, furniture, seating and related wire assemblies.
The current KYA specification lists 0.90mm thickness for M88, M88-1, M88-2 and M88-3.
KYA currently lists four configurations: M88, M88-1, M88-2 and M88-3. Published crown dimensions range from 21.8mm to 32mm.
Both are listed with a 21.8mm crown, 8.5mm inside width and 0.90mm thickness. The current table lists M88 at 20.5mm high and M88-1 at 21.5mm high. M88-1 is also shown with 135H31 as a similar reference.
Do not assume exact interchangeability. KYA labels 135H31 as a similar reference for M88-1. Confirm actual dimensions, collation and tool compatibility before replacement.
The current table lists M88-3 with a 32mm crown, compared with 26mm for M88-2 and 21.8mm for M88 and M88-1.
The current KYA page identifies galvanized steel and lists electro-galvanized and hot-dip galvanized finish options. Confirm the finish for the exact model ordered.
The current application list includes cages and outdoor netting. For outdoor exposure, confirm the required corrosion resistance and select an appropriate finish rather than relying only on the M88 model number.
Yes. Mattress and spring assembly are core applications listed for the M88 family. Select the exact clip according to the wire and spring dimensions.
Yes. The current KYA application data includes sofa bases and sofa backs. Verify the spring and stay-wire dimensions before selecting the M88 variant.
Car and automotive seat assemblies are listed among the applications. Production automotive use should follow the exact clip and assembly specification required by the seat system.
The clip is placed around the wire and spring combination and closed using suitable pliers or a compatible clinch-clip tool so the clip forms around the joined components.
The current M88 product page does not specify one verified tool for every M88 model. Provide the exact M88 variant, current tool model and wire combination so driver, magazine and anvil compatibility can be checked.
The current product family lists strip and roll/polycord collation. Confirm which format is available for the required M88 model and tool setup.
The current KYA table lists 6,000 pieces per carton for M88, M88-1, M88-2 and M88-3.
No. Crown width alone is insufficient. Compare inside width, height, thickness, collation, tool model, wire combination and finished clinch geometry.
Provide the existing clip number, photos or drawing, open clip dimensions, wire diameters, tool manufacturer and model, collation format and intended application.
Contact KYA Fasteners to confirm current sample or trial-order availability. For a new tool or replacement application, test the exact M88 model with the intended wire assembly and clinch tool before volume purchasing.
KYA supplies mattress clinch clips for mattress manufacturers, upholstered-furniture factories, automotive-seat suppliers, wire-product manufacturers, fastener distributors and clinch-tool distributors.
For quotations on M88 mattress clinch clips, provide the required M88 model, existing clip cross-reference, wire dimensions, collation format, finish, clinch-tool model, application, quantity and destination market.
