Fastener Production

Disciplined Production Behind Every Connection

From wire preparation and cold forming through to heat treatment, surface finishing, and packaging, all critical steps are managed on a single campus in one controlled flow.

End-to-End Process

Our Production Journey

From the moment wire enters our plant until finished fasteners are packed and shipped, every stage is managed within a connected, traceable flow.

Wire preparation

Wire Preparation

Cleaning, intermediate annealing, and multi-stage drawing stabilise wire diameter and surface. This extends die life and provides a homogeneous feed material for precise forming.

Cold forming

Cold Forming

High-speed multi-station presses form the head and shank in a single flow. Thread rolling and in-process checks on critical dimensions keep the line stable and within tolerance.

Heat treatment

Heat Treatment

Parts are hardened and tempered in controlled-atmosphere furnaces. Each batch is validated for hardness and microstructure against the target property class before moving to the next stage.

Surface finishing

Surface Finishing

Application-specific coating systems improve corrosion resistance. Labelling, packaging, and palletising follow customer standards so each shipment arrives ready for use.

Wire drawing
Raw Material Preparation

Advanced Wire Drawing

Our state-of-the-art wire drawing lines deliver tight diameter tolerances and homogeneous surface quality.

Following incoming material inspections and certificate verification, surfaces are prepared through cleaning and phosphating. Multi-stage drawing with intermediate annealing follows, managed with full lot-based traceability.

Cold forming
Forming & Precision

Precision Cold Forming

Multi-blow cold forming presses provide dimensional accuracy and repeatability, even at high volumes.

Station count and process sequence are optimised by product type. Die life and change intervals are monitored, with in-process SPC applied on critical dimensions.

Heat treatment and coating
Final Stage

Heat Treatment, Coating & Packaging

After heat treatment, parts are brought to the required hardness and toughness levels; coating and final packaging prepare them for shipment.

Furnace loads are planned with batch-level traceability. Special high-corrosion-resistance coatings can be applied. Packaging follows customer labelling standards.
