Fastener Price
Prices range from ₹50 to ₹5,000 ($0.60-$60) per kg. Carbon steel is economical (₹50-₹500), while stainless and alloy steels reach ₹2,000-₹5,000+. Hot-dip galvanised finishes add a 15%-25% premium. Prices vary by material, grade, and order quantity.
Fastener Industrial Applications
Since Sachiya Steel International distributes industrial fasteners to 4 key industries, the company ensures that each product satisfies the requirements of third-party inspections and the standards that are relevant to the project.
Oil & Gas & Petrochemical
ASTM A193 B7 studs prevent seal leaks during high-pressure hydrocarbon processing. We supply them for flange bolting, refinery piping, and offshore platforms.
Construction & Infrastructure
Applied in steel-framed buildings, bridges, and flyovers. HSFG bolts provide the necessary shear resistance to secure massive structural steel frameworks safely.
Power Generation
Essential for steam turbine flanges, boiler connections, and nuclear reactors. High-temperature B16 studs survive the extreme thermal stresses of continuous energy production.
Automotive & Heavy Engineering
Standard for engine assemblies, chassis connections, and heavy machinery. Grade 8 and Class 10.9 bolts handle the intense vibrations of industrial vehicles.
Shipping & Packaging
Heavy-duty wooden boxes Packing
We strictly follow seaworthy export handling standards to protect fasteners from transit damage, moisture ingress, and surface contamination during long-distance dispatch.
- Heavy-duty wooden boxes with moisture barrier lining
- HDPE stretch film wrapping on all bundles
- Plastic end caps on threaded and plain-end pipes
- Silica gel desiccants to minimize moisture exposure
- ISPM-15 fumigated wooden packaging for export
