Double end threaded studs can also be called two-end threaded screws,they are used on the side of the ship, and the thread lengths at both ends are different. It features a smooth rod body in the middle, which can adapt to hull structures and installation components of different thicknesses.

Double end threaded studs that can fix the radar tower to the edge of the deck. The shorter studs are aligned with the internal deck beams to achieve firm anchoring, while the longer studs can avoid obstacles below. This can prevent drilling through key structures. Just slide the mast base over the stud and add a washer/nut.
Two-end threaded screws for the installation of hull sensors. You can use them to install depth sensors or sonar. The short studs are flush with the ribs, while the long studs span the flat sections. Please use neoprene gaskets and stainless steel nuts. If all the studs are the same, 50% of the studs will not be installed correctly, causing seawater to leak into the cabin.
Two-end threaded screws used to fix the lifeboat winch. Longer studs penetrate the reinforced deck area, while shorter studs are anchored to the lighter deck. Tighten all the studs to 220 N·m with the lock washers. Bolts of inconsistent lengths can damage the structural integrity and cause the hanger to be damaged in a storm.
Double end threaded studs that are flexibly adapted and firmly connected.Due to the complex installation environment on the side of the ship and the varying thicknesses of different components, this type of stud with threads of different lengths can be screwed into the thicker hull structure on one side and fixed to thinner equipment or accessories with nuts on the other side, without the need for additional adjustments to the installation method.
