What is the DOUBLE END STUD BOLTS ?
A double threaded rod, also known as a double-ended stud bolt or double-ended threaded rod, is a fastener that is threaded along its entire length or on both ends, designed to be used in tension applications such as connecting and securing components in machinery, structural frameworks, or industrial equipment.
WHAT ARE THE MAIN TYPES OF STUDS BOLTS ?
Fully Threaded Stud which means a rod threaded along its entire length, used with nuts on both ends for general fastening.
Double-End Stud types can be called threaded at both ends with an unthreaded center (shank), often for alignment or specific positioning.
Tap-End Stud means one end has a short thread (for screwing into a tapped hole), and the other has a longer thread for a nut, common in pipe flanges.
Reduced Shank Stud means it has a thinner center section than the threaded ends, reducing stress and allowing for thermal expansion.
