We supplied 220,000 screw spikes for a railway customer in Argentina. The order specifications included 35K steel and a size of 23 × 105 mm.
This project showcases our experience in railway fastening component supply, manufacturing coordination, quality inspection, and export order documentation. The available project records include production photographs, quality inspection images, factory photographs, a proforma invoice, an export bill of lading, and packaging and shipment photographs.

Screw spike manufacturing for an Argentina railway fastening order
Quality Inspection & Dimensional Verification
Quality inspection is an important part of railway fastening component supply. Screw spikes should be evaluated against the approved drawings, purchase requirements, and applicable technical specifications.
Depending on the agreed inspection plan, relevant checks may include:
Dimensional verification: Checking the specified dimensions against the approved drawing.
Thread inspection: Reviewing thread dimensions and condition where required.
Visual inspection: Checking for visible surface defects, damage, or unacceptable irregularities.
Material verification: Reviewing the specified material grade and available material documentation.
Quantity verification: Confirming the quantity prepared for delivery against the order.
The actual inspection methods, acceptance criteria, and results must be based on the available inspection records. The list above describes potential inspection items and does not independently confirm that every test was performed or passed on this order.

Factory Facilities & Manufacturing Environment
Manufacturing facilities and production arrangements are important considerations when sourcing railway fastening components in bulk.
Our factory photographs provide a view of the working environment behind railway component manufacturing and supply. For project-specific orders, production requirements should be confirmed against the customer's drawings, material specifications, and agreed quality requirements.


Packaging & Export Shipment
For bulk railway fastening orders, packaging and shipment preparation should take into account product dimensions, handling requirements, shipment quantity, and destination arrangements.
The available photographs document the packaging and shipment preparation associated with this screw spike order. These images help show how the products were prepared for export.


Export Documentation & Shipment Record
Export documentation is an important part of international railway component supply. A bill of lading provides shipment-related information that can help buyers and logistics teams verify the documented consignment details.
