Grade:
- Low carbon steel
- Medium carbon steel
- High carbon steel
- Alloy steel
- Stainless Steel
- Brass
Fabrication
The production of set screws can be divided into seven steps: annealing (pickling), wire drawing (molding), grinding teeth (level surface treatment), heat treatment and level surface treatment.

Quality Inspection
The majority of fasteners fall under the category of nuts and bolts in seemingly endless variations; they are one of the most important fastening elements and can be found essentially everywhere. They are used in the construction of complex machinery and equipment, as well as vehicles and buildings. Since mechanical stress is concentrated on these types of connection points, the integrity of fasteners is extremely important.
- Size and appearance inspection
- Hardness Tests
- Surface roughness inspection
- Surface Defect Detection
- Tensile Test
- Torque Test
- Thread Damage Inspection
- Quality records and document management
