Industrial Fasteners — Bolts, Nuts, Screws & Washers (Export-Ready)
Supplying precision fasteners across automotive, construction, machinery and energy sectors — certified, tested and packed for trouble-free installation.
Product Range & Applications
We export a wide range of industrial fasteners: hex bolts, carriage bolts, shoulder bolts, machine screws, self-tapping screws, hex nuts, flange nuts, locknuts, washers (flat, spring). Common materials: Carbon steel (grades 4.6, 8.8, 10.9, 12.9), Stainless steel (304, 316) and alloy steels. Typical applications: automotive assemblies, structural bolts for construction, heavy machinery, wind turbines, rail and marine fittings.
- Thread types: UNC/UNF, metric coarse/fine, BSP/BSW on request.
- Surface treatments: Electro-galvanized, hot-dip galvanised, zinc flake, black oxide, PTFE coating.
- Custom lengths, thread engagement, and chamfering per drawing.
Typical Export Specifications
Note: We can produce to OEM drawings and provide sample runs for approval.
Common Issues in Fastener Supply Chain & How We Mitigate Them
Precision fasteners require control across material, machining, heat-treatment and coating stages. We work with vetted manufacturers and perform incoming & outgoing inspections to ensure compliance.
1) Material & Heat-treatment Variability
- Raw material certificates (MTC) required from mills.
- Batch-wise hardness and tensile tests (UT/Charpy where needed).
- Controlled quench & temper cycles; traceable heat numbers.
2) Thread & Dimensional Tolerance
- Gauge checks for pitch, pitch diameter, and major diameter.
- Profile projectors and CMM sampling for critical dimensions.
- Thread rolling vs cutting per spec to ensure fatigue life.
3) Coating Adhesion & Corrosion Resistance
- Salt spray (ASTM B117) tests and adhesion tests on sample lots.
- Passivation for stainless, zinc flake for high-corrosion zones.
- Controlled stoving ovens for lacquer / PTFE layers.
4) Packaging & Transit Damage
- Shock-resistant cartons, sealed poly-bags inside cartons.
- Wooden cases for large fasteners or precision sets.
- Vibration-resistant packing and corner protection for export boxes.
5) Certification & Traceability
- ISO 9001 systems, MTC, and batch traceability to heat numbers.
- Pre-shipment inspection reports & torque test certificates.
- Sample retention and buyer approval samples for series shipments.
6) Counterfeit & Quality Risk
- Only approved mills and process houses used; supplier audits.
- Holographic labeling or barcoded kits for high-value fasteners.
- Third-party lab testing available on request.
