Multifunctional Sealing & Anti-Loosening Screw
The Multifunctional Sealing & Anti-Loosening Screw replaces three separate parts — a fastener, a seal and a vibration damper — with one engineered component. Under the head sits a high-performance sealing element; when the screw is tightened, that element is compressed and flows into the clearances of the joint.
The compressed seal closes the gaps between the head, the panel and the thread, blocking water, dust and pressurized fluid from the fastening point. Because sealing happens as part of tightening, it requires no sealant, no gasket assembly step and no cure time, so the joint is sealed the moment the tool comes off.
The design also damps vibration. The elastomeric element absorbs part of the dynamic load that would otherwise work the screw loose, so preload is retained in equipment that sees continuous vibration. Fewer parts, fewer process steps and a joint that stays sealed and tight — the practical result is simpler assembly and more reliable equipment.
Extensively used in outdoor communication cabinets, new-energy battery packs, hydraulic equipment and smart meters, these screws are ideal for interfaces that demand strict waterproof protection, leakage prevention or resistance to sustained vibration.
They meet professional requirements for sealed, maintenance-friendly fastening, and are equally suitable for outdoor instrumentation, charging equipment and industrial control enclosures exposed to weather and washdown.
