Material review
Raw material requirements and Mill Test Certificates are checked against the order specification.
Quality control
Quality at source.
Every batch is checked against the approved specification before release.

A controlled process.
Quality is built into material selection, production verification and documented order release.
In-process verification
Cold forming and thread rolling are monitored with the gauges and controls required for the approved part.
Release documentation
Inspection records and relevant material documentation are prepared before shipment.
Dimensions and threads.
In-house dimensional inspection confirms that critical features match the drawing, standard and approved sample.
- Digital calipers and micrometers for critical dimensions
- Go/No-Go thread gauges for functional thread verification
- Visual checks for surface condition and part consistency
Strength and corrosion.
When applicable, batches are verified in our laboratory through mechanical and environmental testing.
- Tensile strength evaluation for mechanical performance
- Vickers hardness testing for material condition
- Neutral Salt Spray testing for corrosion resistance
Standards and traceability.
DIN, ISO and ANSI requirements guide the approved product specification. Relevant orders are supplied with complete Mill Test Certificates (MTC 3.1).
Specification control
The order, drawing, material and finish requirement are aligned before production release.
Batch evidence
Inspection and material records provide a clear documentation route for the approved shipment.
