Forming Route A

Hot Forging

Heated steel bar is formed under high pressure for larger or specialized fastener geometries.

Inspector measuring a threaded fastener selected for sampling
In-Process Quality Check

Sampling Inspection

Selected production samples are checked for critical dimensions and thread geometry using calibrated instruments.

Operator checking plated fasteners on a surface-treatment rack
Surface Finishing

Surface Treatment

Specified finishes are applied and checked for consistent coverage and corrosion protection.

Final packed fasteners checked before container loading
Final Release

Inspection & Packing

Final inspection, traceability checks and protected packing prepare each order for shipment.

Titanium.
Built to Endure.

Choose titanium for less weight, corrosion resistance and longer service life in marine, chemical and high-performance assemblies.
