Common Misconceptions When Choosing Fully Threaded Studs, Threaded Rods, and Stud Bolts

In both daily applications and heavy industrial projects, fully threaded studs, threaded rods, and stud bolts play a critical role in ensuring the safety and stability of structures. However, many users often fall into common selection pitfalls that can compromise performance and even create safety risks.

As a leading manufacturer of stud bolts and threaded rods in China, ASM Fastener has specialized in the production of high-strength fasteners for over 14 years, supplying major shipbuilding, FPSO, and petrochemical projects worldwide. Based on our experience, we have summarized several key misconceptions to help customers make more informed choices.

1. Ignoring Material Selection

When selecting fully threaded studs or rods, the material should always be chosen according to the specific service environment—including factors such as temperature, corrosion, and pressure. Using inappropriate materials can lead to premature failure and unnecessary maintenance costs. ASM Fastener provides a wide range of materials including ASTM A193 B7/B7M, A320 L7/L7M, B8/B8M Class 1 & 2, and B16, ensuring performance under the most demanding conditions.

2. Overlooking Mechanical Properties

A common mistake is focusing solely on the product’s appearance while neglecting its mechanical performance. Qualified fasteners must come with certified test reports and clear strength grade markings to ensure they meet engineering requirements. At ASM Fastener, every batch of products undergoes rigorous mechanical testing—including tensile, hardness, and impact testing—to guarantee consistent performance and traceability.

3. The “Tighter is Better” Misconception

Many still believe that tightening a bolt as much as possible ensures safety. In reality, over-tightening can cause excessive tensile stress, plastic deformation, or even fracture of the fastener, reducing overall joint integrity. Proper torque application and the use of calibrated tools are essential for safe installation.

4. Ignoring Compatibility of Components

Nuts and washers must match the material, dimensions, and strength grade of the stud or rod. For high-demand connections, the use of lock nuts or special washers can significantly improve the safety and reliability of the assembly. ASM Fastener provides complete fastener sets with perfectly matched components to ensure optimal performance.

5. Neglecting Special Application Requirements

In corrosive, high-temperature, or offshore environments, standard fasteners may not be sufficient. Engineers must consider surface treatments, coatings, and customized dimensions to meet specific environmental challenges. ASM Fastener offers customized production based on client drawings and specifications, ensuring each fastener fits its intended use perfectly.
