Industrial fastening requires products that deliver strength, accuracy, and consistent performance. Components such as threaded rod, allen bolt, anchor bolts, machine screw, and tapping screw are used in construction, engineering, heavy machinery, and manufacturing industries where every connection must be dependable.
At SIW India, our focus is on manufacturing precision fasteners that meet the demands of modern industries. Every product is manufactured using quality raw materials, advanced production processes, and strict quality inspections to ensure reliable performance.
Threaded Rods Manufactured for Strength and Stability

A Threaded Rod is a versatile fastening component with threads running along its entire length. It is widely used where strong support and adjustable fastening are required.
Our threaded rods are manufactured for applications including:
- Structural steel fabrication
- Industrial equipment installation
- HVAC systems
- Electrical and plumbing support
- Infrastructure projects
Each threaded rod is produced with precise threading and dimensional accuracy to ensure easy installation and a secure fit.
Allen Bolts for Precision Engineering
An allen bolt, also known as a socket head bolt, is widely used in machinery and mechanical assemblies where high tightening force and a compact design are required.
At SIW India, allen bolts are manufactured with:
- Accurate thread profiles
- High-strength steel
- Precision-machined socket heads
- Consistent dimensional tolerance
- Durable surface finishes
These features ensure reliable fastening in demanding industrial applications.
Anchor Bolts Built for Heavy-Duty Installations
Anchor Bolts provide the foundation for securing heavy structures and equipment to concrete. They are commonly used in construction, industrial plants, bridges, and infrastructure projects.
Our manufacturing process ensures every anchor bolt offers:
- Excellent load-bearing capacity
- Strong grip in concrete foundations
- High tensile strength
- Long service life
- Consistent manufacturing quality
Each anchor bolt is inspected to meet industry standards before dispatch.
Machine Screws for Accurate Assembly
A machine screw is an essential fastening component used in electrical equipment, machinery, automotive parts, and precision assemblies. Manufacturing accuracy is critical to ensure proper fit and dependable performance.
Our machine screws are produced with:
- Precision threading
- Uniform dimensions
- Smooth surface finish
- Reliable fastening performance
These qualities help improve assembly efficiency while maintaining long-term durability.
Tapping Screws for Fast Installation
A tapping screw is designed to create its own threads during installation, making it suitable for sheet metal, plastic, and light engineering applications.
Manufactured with precision-cut threads and quality materials, our tapping screws provide:
- Quick installation
- Secure holding strength
- Reduced assembly time
- Consistent performance
They are widely used in fabrication, electrical work, appliance manufacturing, and industrial production.
