Available Types of Bolts
We manufacture and export various bolt types to suit different applications:
⚪️ Hex Bolts – For high-strength mechanical joining
⚪️ Heavy Hex Bolts – Designed for heavy-load industrial structures
⚪️ Carriage Bolts – Ideal for wood or metal with smooth dome heads
⚪️ Flange Bolts – Built-in washer head reduces stress concentration
⚪️ Custom Bolts – Manufactured per client specifications or drawings
⚪️ And Much More
Each type is available with optional full or partial threading, and we provide metric (M series) and inch sizes ranging from M5 to M100 or ¼” to 4”.
Materials & Grades
We supply bolts in a variety of materials suited for both standard and extreme environments:
1. Mild Steel (MS) – General-purpose, cost-effective
2. Stainless Steel (SS304, SS316) – Corrosion-resistant, suitable for marine & food-grade use
3. High-Tensile Steel (Grades 8.8, 10.9, 12.9) – For heavy engineering and structural loads
4. Alloy Steel (B7) – High-strength, temperature-resistant applications (e.g., oil & gas)
We also offer coating and plating options such as:
✪ Zinc Plated (Clear / Yellow)
✪ Hot-Dip Galvanized (HDG)
✪ Black Oxide
✪ Dacromet Coating
✪ Xylan / PTFE (non-stick & chemical-resistant)
Applications
Our bolts are designed to perform under extreme conditions. Industries and applications include:
- Construction & Civil Infrastructure – Used for bridges, tunnels, scaffolding, rail tracks, and heavy concrete anchoring
- Automotive & Transport – Essential for chassis assembly, suspension systems, engines, gearboxes, and heavy-duty axles.
- Oil & Gas, Petrochemical – High-strength bolts that perform under high pressure, heat, and corrosive conditions in refineries and pipelines.
- Renewable Energy – Securing solar panels, wind turbine towers, and hydroelectric machinery in variable climates.
- Industrial Machinery – Vital for OEM assembly, fabrication plants, power transmission systems, and equipment maintenance.
- Power & Electrical – Used in transmission towers, switchgear, and electrical panel mounting.
