Double-End Studs are threaded fasteners featuring threaded sections at both ends with an unthreaded portion between them. They are commonly used for flange connections, equipment assemblies, and applications where one end of the stud is installed into a tapped hole while a nut is used on the opposite end to secure a component.
Double-End Studs can be manufactured with equal or application-specific thread lengths at both ends. The unthreaded shank is generally maintained in relation to the nominal diameter, depending on the design and applicable specification.
Adore Industries manufactures and supplies Double-End Studs in different sizes, materials, thread configurations, and surface treatments. Thread fit and dimensional requirements can be controlled according to the tapped-hole and assembly specifications.

How Double-End Studs Work
One threaded end of the stud is installed into a compatible tapped hole in the equipment, flange, or structural component. The component to be secured is positioned over the exposed end, and a suitable hex nut is tightened onto the external thread.
This arrangement provides a practical fastening method for assemblies where repeated installation and removal of the attached component may be required.
