Galvanized Grade 8.8 Bolt and Nut
Product Overview
This order consisted of a complete range of galvanized bolt and nut sets in various configurations, each paired with non-asbestos gaskets for reliable sealing performance:
| Product | Size | Description | Standard | Material | Note |
|---|---|---|---|---|---|
| Galvanized Bolt and Nut | M16 × 75 | 8 pcs per set with one non-asbestos gasket | — | Grade 8.8 | Cold galvanized |
| Galvanized Bolt and Nut | M16 × 70 | 4 pcs per set with one non-asbestos gasket | — | Grade 8.8 | Cold galvanized |
| Galvanized Bolt and Nut | M20 × 90 | 4 pcs per set with one non-asbestos gasket | — | Grade 8.8 | Cold galvanized |
| Non-Asbestos Gasket | NP16 NO100 – NO200 | Supplied together with each bolt set | EN Standard | — | Heat and chemical resistant |
Each assembly was carefully inspected to ensure perfect dimensional accuracy and uniform galvanizing thickness. The products were delivered within 2–3 days after cold galvanizing, ensuring fast turnaround while maintaining quality standards.
Non-asbestos gaskets ready for shipment to Montenegro
Reliable Sealing and Fastening Solution
The combination of galvanized bolts and non-asbestos gaskets provides an ideal solution for pipeline flanges and industrial equipment connections. The gaskets deliver excellent sealing performance, thermal stability, and chemical resistance, while the bolts and nuts provide secure, high-torque fastening even under fluctuating pressure or temperature.
This ensures leak-free operation and mechanical reliability across critical installations, including oil & gas facilities, power plants, and water treatment systems.
