Service managers and electronics makers know the scenario: a customer brings in a device and says "I didn't do anything, it just switched off." But on the bench you find screwdriver marks, a missing part or liquid damage.
That's when the customer's word collides with technical reality. Without solid evidence on the device's screws, you end up absorbing the cost. It's one of the biggest profit leaks I've seen in the industry.
Here's a small solution with a huge impact that ends these disputes: VOID warranty labels over screws.
Why Every Screw Needs a Guard
Warranties on laptops, phones, consoles and routers usually depend on the device not being opened by unauthorized people. But that's hard to prove.
A screw seal label goes over the screws holding the case together. Usually very small (e.g. 5 or 10 mm), it physically blocks the screwdriver from the screw head.
The moment a user presses a screwdriver in, the label breaks. Your technician sees the damaged label and confirms in seconds that the device is out of warranty.
How Do Service Security Labels Work?
An ordinary paper label can be warmed with a hair dryer and peeled off. VOID-based security labels have special adhesives that grip tiny metal surfaces like screw heads.
- Sensitive response: the label self-destructs at the slightest attempt to remove it.
- Residue: even if peeled off, it leaves a mark on the screw head that is hard to clean.
- Deterrence: "Warranty void if removed" discourages users from tampering.
B2B Comparison: Cost vs Return
| Situation | Device without label | Device with VOID screw seal |
|---|---|---|
| Time to detect | 15-30 minutes (inspection) | Seconds (visual check) |
| Customer disputes | High risk of argument. | Evidence speaks for itself. |
| Risk of abuse | Very high | Minimal |
Which Size and Type?
There's no standard size; choose to fit your device. We can cut labels precisely to the millimeter.
We usually recommend round warranty labels around 3-5 mm for phones and 8-10 mm for laptops and consoles. See also destructible vs VOID labels.
