Threaded Rods for Structural Fastening – Strength, Materials & Custom Cuts

When your application demands long-length fasteners, high-tension joins, or custom-length threading, there's one solution that delivers unmatched flexibility and strength: the Threaded Rod.

Also known as a stud, all-thread, or threaded bar, this fastener plays a crucial role in construction, machinery assembly, electrical installation, and equipment manufacturing.

In this guide, Dongguan Sango Hardware Fasteners Co., Ltd., a direct manufacturer of industrial fasteners, explains the types, applications, and custom options for Threaded Rods in modern projects.

1. What Is a Threaded Rod?

A Threaded Rod is a long, straight rod that’s threaded along its entire length or partially threaded at both ends. It functions as a versatile tension member or anchor, connecting parts across extended distances.

🔩 Main Functions:

• Structural anchoring
• Load-bearing joints
• Spacer or standoff component
• Custom-length fastener for large equipment
• Embedded bolt in concrete or epoxy structures

2. Types of Threaded Rods

🔹 Fully Threaded Rod

• Continuous thread over the entire length
• Used for high-tension applications and long-distance joining

🔹 Double-End Threaded Rod (Stud)

• Threads on both ends, center is smooth or milled
• Ideal for mounting motors, pumps, flanges

🔹 Left-Hand Threaded Rod

• Opposite threading direction for specific mechanical systems
• Used in rotating equipment or tension balancing

🔹 Metric & Inch Threaded Rod

• Metric: M4 to M30
• Inch: #8-32 to 1"-8 UNC or UNF

🔹 Customized Cut Rods

• Tailored to specific lengths, thread lengths, and ends (chamfered, flat, slotted)

3. Where Are Threaded Rods Used?

Threaded rods are critical in:

• 🏗 Steel frame construction and anchor bolts
• ⚙️ Heavy machinery mounting
• 🔌 Electrical cabinet bracing
• 🧱 HVAC and plumbing supports
• 🪛 Custom fabrication of fixtures and molds
• 🚗 Automotive engine assembly and exhaust systems

They’re also used for seismic bracing, curtain wall suspension, and equipment leveling bases.
