Product overviewOverview
Bond strength depends on three things: surface preparation, adhesive thickness and cure. A bonded nut puts the thread on the blind side without a hole through the panel, so the visible face stays uninterrupted. Load is carried by the bonded base in shear, and the thread has to be protected from adhesive during bonding, since cured adhesive in the thread cannot be removed without damaging it.
Material: Carbon Steel / Stainless Steel. It is bonded with structural adhesive after the surfaces are prepared.
Key featuresFeatures
- Thread on the blind side with no through hole.
- Load transfers through the adhesive in shear, avoiding hole stress concentration.
- Suits thin sheet, composites and non-weldable substrates.
- Bases with a glue reservoir or knurl control bond-line thickness and add mechanical keying.
Typical applicationsApplications
- Curtain wall and decorative panels
- Appliance exterior parts
- Composite panel attachments
Selection notesSelection
Use a masking plug or a thread-safe adhesive application; adhesive that reaches the thread has to be cleared before cure, not after.

What matters during installation of the Bonding Nuts?
| Material | Carbon Steel / Stainless Steel |
|---|---|
| Adhesive | Epoxy / Cyanoacrylate |
| Standard | GB/T 7124 (lap shear), customer drawing |
| Installation | structural adhesive after surface preparation |
| Typical substrate | composites, thin housings, decorative panels |
| Key inspections | pull-off/shear strength, bond-line thickness, ageing |
Pull-off and shear tests are sampled per lot, recording whether failure is interfacial or cohesive.We recommend a pilot assembly at the actual torque and mating part before locking the process parameters for volume.
