Suitable for steel structure connections, curtain wall fixing, foundation embedding and prefabricated building joints.
Suitable for equipment assembly, machine frame connections, maintenance replacement and anti-loosening in vibration environments.
Suitable for heavy-load connections, weather resistance and long-term outdoor service environments.
Suitable for solar mounting brackets, roof fixing and outdoor corrosion-resistant installation systems.
Different environments require different strength grades, surface finishes and standards.
| Application | Recommended grade | Common sizes | Surface finish | Standards |
|---|---|---|---|---|
| Construction | Grade 8.8 / 10.9 | M8-M36 | Hot-Dip Galvanized / Dacromet | GB / DIN |
| Machinery | Grade 8.8 / 12.9 | M3-M24 | Black Oxide / Zinc Plated | GB / DIN / ISO |
| Bridges & Tunnels | Grade 10.9 | M16-M42 | Hot-Dip Galvanized / Dacromet | GB / ASTM |
| Solar Energy | A2-70 / A4-80 | M6-M16 | Stainless Steel / Hot-Dip Galvanized | GB / DIN |
Guidance on strength grade, surface finish, custom parts and batch delivery for project procurement.
Construction, bridges, machinery and solar mounting should be matched by load, vibration, installation environment and standards. Wohe can recommend grades such as 4.8, 8.8, 10.9, 12.9 and stainless steel options.
For outdoor, humid or corrosive conditions, hot-dip galvanizing, Dacromet, stainless steel or anti-loosening solutions are usually considered first. The final choice depends on salt spray requirements, location, budget and maintenance.
Please provide drawings, dimensions, material, strength grade, surface finish, quantity, acceptance standard and application. Samples or application notes can also help Wohe confirm feasibility.
Send working environment, size and quantity requirements. We can help match suitable product series.
