Product and Interface Review
Thread standard, nominal diameter, pitch, threaded length, overall length and end form must be stated together. Mechanical properties and corrosion suitability depend on the specified material standard, heat treatment and test route. Matching nuts, washers and anti-galling installation practices should be considered as part of the complete bolted joint.
Key Manufacturing Features
- Threaded ends with smooth center shank
- Metric, UNC, UNF and drawing-based thread options
- Custom identification and traceability marking
- Matching duplex nuts and washers available by specification
Materials, Manufacturing and Surface Finish
Production begins with verified 2507 bar stock followed by turning and thread manufacture to the selected dimensional standard. Thread rolling or cutting is chosen from size, quantity and specification. Cleaning, passivation, marking and packaging are controlled to the purchase order.
The proposed route for this double-end stud bolt is Bar preparation, CNC turning, thread rolling or cutting, marking and passivation as specified. Final material, tolerances, finish and testing remain subject to the approved drawing and purchase specification.
