Surface Treatment Options
Zinc Finish
The zinc finish provides a bright metallic appearance and is suitable for general building and industrial fastening. It can be used for threaded connections, equipment assembly, structural support and machinery installation where a zinc-treated surface is required.
Plain Finish
The plain finish is suitable for applications that require further processing, painting, coating or a specific surface-treatment system. It can also be used in controlled indoor assemblies where additional surface treatment is arranged separately. The final surface treatment should be selected according to the material, grade, working environment and project requirements.
Application
This double ended stud bolt can be used in the following applications:
- Building construction
- Steel structure assembly
- Machinery installation
- Equipment mounting
- Flange fastening
- Bracket and support installation
- Industrial frame assembly
- Mechanical maintenance
- Threaded sleeve connections
- Heavy equipment fastening
- Structural component installation
- General metric fastening systems
The double ended configuration allows a component to be secured between two threaded connection points. The stud bolt can be installed through a plate, flange, bracket or support structure and fixed with matching nuts and washers.
For building and industrial projects, the selected material and grade should match the expected load, vibration, temperature, corrosion exposure and installation conditions. The available options allow buyers to select between steel and stainless steel materials, as well as grades including 4.8, 8.8, 10.9, A2-70 and A4-80.
Matching Fasteners
| Stud Bolt Size | Matching Components |
|---|---|
| M4 | M4 nuts, flat washers, spring washers and threaded sleeves |
| M5 | M5 nuts, flat washers, spring washers and threaded sleeves |
| M6 | M6 nuts, flat washers, spring washers and threaded sleeves |
| M8 | M8 nuts, flat washers, spring washers and threaded sleeves |
| M10 | M10 nuts, flat washers, spring washers and threaded sleeves |
| M12-M36 | Matching metric nuts, washers and coupling sleeves according to the selected size |
Flat washers can help distribute the clamping force across the connected surface. Spring washers may be used where additional resistance to loosening is required. Coupling nuts and threaded sleeves can be used for extended threaded connections.
The nuts, washers and sleeves should match the same nominal thread size and should be selected with a compatible material and strength grade.
