What Are Threaded Rods? Types, Uses, Specifications & Complete Buying Guide

Sachiya Steel International, a leading threaded rods manufacturer in India, provides high-quality threaded rods for construction, machinery, and industrial applications. Threaded rods are long, straight rods with threads along their length or at both ends, allowing nuts and bolts to fasten materials securely. Unlike regular bolts, threaded rods are highly versatile, suitable for both heavy-duty and everyday projects.

What Are Threaded Rods?

A threaded rod is essentially a fastener used to join or stabilize objects. It can be fully threaded, partially threaded, or double-ended. These rods come in different materials like stainless steel, carbon steel, brass, or zinc-plated steel, each chosen based on the environment and load requirements.

Types of Threaded Rods

Threaded rods are available in several types to suit different needs:

Fully Threaded Rods

Fully Threaded Rods have threads that run along their entire length, allowing for maximum adjustability and strong, consistent grip throughout the rod. They are widely used in construction, machinery, and repair work where full-length threading is needed for flexibility and secure fastening.

Double Ended Threaded Rods

Double Ended Threaded Rods feature threads on both ends while the center section remains unthreaded. These rods are used to connect two components together, making them ideal for situations where alignment and stability are important, such as joining mechanical parts or extending connections.

Zinc Plated Threaded Rods

Zinc Plated Threaded Rods come with a protective zinc coating that helps resist rust and corrosion. This makes them especially suitable for outdoor environments, humid areas, and applications where exposure to moisture is common. The coating enhances durability and increases the rod’s service life.

Body Studs

Body Studs are heavy-duty threaded rods designed for high-strength applications. They are commonly used in engines, machinery, and industrial equipment where strong, reliable fastening is essential. Their robust design ensures stability even under high stress or heavy load conditions.

Uses of Threaded Rods

Threaded rods are extremely versatile and widely used across industries:

  • Construction: Securing beams, walls, and frameworks.
  • Machinery and Equipment: Assembly of machines and industrial components.
  • DIY Projects: Furniture building, shelves, and home repairs.
  • Plumbing and Electrical: Supporting pipes, conduits, and cable trays.
