Square Sleeve Nut Special Nut One Way Galvanizing

Square sleeve nut is one of the sleeve nuts, sleeve nut is a nut used instead of a turnbuckle when high strength rods are required. It is used to a couple of rods and provides some degree of length adjustment. It is stronger than the corresponding connecting rod of the same materials. It is produced from hexagonal or round bars (usually stainless steel). It is given a plain finish. Ever Hardware provides custom-made fasteners and customizable packaging.
A turnbuckle, stretching screw, or bottlescrew is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threaded eye bolts, one screwed into each end of a small metal frame, one with a left-hand thread and the other with a right-hand thread. The tension can be adjusted by rotating the frame, which causes both eye bolts to be screwed in or out simultaneously, without twisting the eye-bolts or attached cables.
Turnbuckles are most commonly used in applications which require a great deal of tension; they can range in mass from about ten grams for thin cable used in a garden fence, to thousands of kilograms for structural elements in buildings and suspension bridges.

Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion-resistant, multi-layered coating of zinc-iron alloy and zinc metal.  While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc.  This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part.
