Stud Bolts: Design, Installation, and High-Pressure Uses

This page focuses on stud bolts—headless, fully/partially threaded rods with threads on both ends, designed to screw into a tapped hole and accept a nut. It explains their advantage over bolts: even torque application without a head, reducing material damage, and easier component alignment. Materials include carbon steel, alloy steel, stainless steel (304, 316), and heat-resistant alloys (Inconel) for high-temperature/pressure settings. Applications in piping (flange connections), automotive (cylinder heads), and machinery are explored, along with installation steps (cleaning holes, torqueing) and selection criteria based on load, temperature, and corrosion exposure.

Frequently Asked Questions

What is the process for installing stud bolts?

Installing stud bolts involves first cleaning the tapped hole to remove debris. The stud bolt is then screwed into the hole by hand or with a stud driver until it is tight (often using a torque wrench to ensure proper seating). Once the stud is secure, the component to be fastened is positioned over the exposed thread. A nut is then tightened onto the stud using a torque wrench, applying the specified torque to achieve the correct clamping force. For critical applications, thread-locking compounds may be used to prevent loosening due to vibration.

Theodore Moore

These stud bolts were critical for our industrial piping project, securing flanges under high pressure and temperature. The alloy steel 10.9 grade handled the 300 psi pressure effortlessly, and the fully threaded design ensured uniform load distribution. We used them with spiral-wound gaskets, and the consistent torque application created a leak-free seal. The bolts are easy to inspect for stretch or damage, and the galvanized coating protected them from rust in our humid plant. A top choice for any piping system requiring reliable flange connections.
