Stud bolts are threaded rods with threads on both ends, designed to be screwed into a tapped hole or secured with a nut on one end. They typically have a plain shank in the middle, with threads at each end. Stud bolts are commonly used in conjunction with nuts to fasten flanged connections in pipelines, pressure vessels, and machinery.
Key characteristics:
Threaded on both ends.
Used to create a permanent or semi-permanent joint.
Available in various materials, sizes, and thread configurations.
Essential for ensuring the integrity and stability of critical connections in industrial applications.
Nuts:
Nuts are fasteners with a threaded hole, designed to be tightened onto the threaded end of a bolt, stud bolt, or screw. They come in various shapes and styles, such as hexagonal nuts, square nuts, and wing nuts, each suited to different applications. Nuts are crucial components in fastening systems, providing the means to secure bolts and studs and create a tight, secure joint.
Key characteristics:
Threaded hole to fit onto the threaded end of a bolt or stud.
Available in different shapes, sizes, and materials.
Used in conjunction with bolts or stud bolts to fasten components together securely.
Essential for maintaining structural integrity and preventing loosening or disassembly of fastened joints.
Stud Bolt Types:
Fully Threaded Studs: These studs have threading along their entire length, allowing nuts to be screwed onto either end. They are versatile and commonly used in applications where adjustability or flexibility in bolt length is required.
Tap End Studs: Also known as tap-end studs, these studs have threads on one end and a plain shank on the other end. They are designed to be screwed into a tapped hole on one side, providing a flush surface for a nut to be tightened onto the threaded end.
Double End Studs: These studs have threads on both ends, with equal or unequal lengths of threading. They are used to secure two components together by threading a nut onto each end, providing a more balanced and symmetrical fastening solution.
Continuous Thread Studs: Continuous thread studs have threading along their entire length, without a distinct break between the threaded and unthreaded portions. They are suitable for applications requiring a strong and uniform connection across the entire length of the stud.
Nut Types:
Hex Nuts: Hex nuts are the most common type of nut, featuring six flat sides and a hexagonal shape. They are widely used in conjunction with bolts and stud bolts, offering a secure and stable fastening solution.
Heavy Hex Nuts: Similar to hex nuts but with larger dimensions and thicker walls, heavy hex nuts provide increased strength and durability. They are commonly used in high-strength and high-pressure applications where standard hex nuts may not suffice.
Nyloc Nuts: Nyloc nuts feature a nylon insert at the top of the internal threads, which helps prevent loosening due to vibration or shock. They are often used in applications where secure and reliable fastening is crucial.
Flange Nuts: Flange nuts have a built-in washer or flange at the base, which provides a larger bearing surface and helps distribute the load more evenly. They are suitable for use in applications where the fastened components may exert lateral forces or require increased resistance to loosening.
Wing Nuts: Wing nuts feature two large wings or projections on either side, allowing for easy hand tightening and removal without the need for tools. They are commonly used in applications where frequent assembly and disassembly are required, such as in fixtures and temporary installations.
