Materials and Manufacturing Process
The A194 Grade7 Alloy Steel Hex Nuts are made from high-grade alloy steel known for its strength-to-weight ratio and excellent mechanical properties. This grade of steel is particularly suited for applications requiring high tensile strength and good fatigue resistance.
The typical production process includes:
- Raw Material Selection (Alloy Steel Bars)
- Forming: Cold Forming or Hot Forging
- Heat Treatment: Quenching + Tempering to achieve mechanical properties
- Surface Treatment: Zinc Plating / Black Oxide / Galvanization
- Thread Cutting or Rolling
- Final Inspection and Sorting
- Packaging & Labeling
These precise methodologies ensure the consistency, reliability, and optimum performance of each nut delivered by Flybear Fastener.
