Is the Stud Bolt a high-quality fastening solution for industrial applications?
2025-08-04
What Are Stud Bolts?
Stud bolts are threaded fasteners designed for high-pressure and high-temperature applications, commonly used in flanged connections for pipelines, valves, and pressure vessels. ZHELI's bolts consist of a fully threaded rod, often paired with two heavy hex nuts to secure flanges tightly.

Stud Bolt FAQ
1. What is the difference between a stud bolt and a standard bolt?
Stud bolts are fully threaded rods used with two nuts, primarily for flange connections, whereas standard bolts have a partially threaded shank and a head for direct fastening. Stud bolts provide better load distribution and are ideal for high-pressure sealing.
2. How do I choose the right stud bolt material for my application?
Consider the operating environment—carbon steel (B7) is ideal for general industrial use, stainless steel (B8) for corrosive settings, and alloy steel (L7) for extreme temperatures. Always check pressure ratings and compliance with industry standards.
3. Can stud bolts be reused after installation?
Yes, but only if they show no signs of wear, corrosion, or thread damage. Reusing bolts in critical applications (e.g., high-pressure systems) requires thorough inspection to ensure structural integrity.
