Sized for a 5\/8-11 coarse thread, this\nextended nut connects two lengths of threaded rod, or two bolts, end to end,\nwhich makes it the standard way to lengthen all-thread rod for hanging,\nmounting, and structural tie-rod work in wet or exposed settings. The long\nsix-sided body is internally threaded from end to end, so a rod or bolt can be\nturned in from each side until the two meet inside. A wrench grips the six\nflats to hold or drive the coupling, drawing both threaded ends into a strong,\nstraight, well-aligned joint that carries load along the full run. Made from\n18-8 stainless steel, the coupling nut resists rust, corrosion, and staining\nfar better than plated hardware. It keeps clean internal threads and a secure\njoint in marine, coastal, and washdown settings, so an extended rod run stays\nstrong and true rather than seizing or corroding at the connection over time.\nUse these coupling nuts for extending all-thread rod, hanging fixtures and\nHVAC equipment, and plumbing or marine supports where two threaded ends must\nbe joined. Match the size and thread pitch to your rod for a clean, full-depth\nfit. This 2-piece pack provides a ready supply for marine, plumbing, and\nstructural projects on the job site. From the Manufacturer Hex Coupling Nuts\nare are defined by their elongated hexagonal shape and used to connect two\npieces of threaded material at opposite ends.
