Use a rod coupling nut to extend space or level a threaded rod or stud Coupler nuts also allow you to connect two threaded rods Reducer coupler nuts connect threaded fasteners with different diameters like a metric bolt and a standard rod For high moisture situations choose a coupler nut with a zinc chromate finish Grainger has a full selection of rod coupling nuts to 2019 12 23 nbsp 0183 32 Earth Rods Diameter v Length A frequently made misconception is that there is a direct and clear correlation between the diameter of the earth rod used and the effect on lowering earth resistance readings this however is false The resistance value is only decreased by 9 5 by doubling the diameter of the rod which means increasing the weight and the cost of the rod by Slightly less corrosion resistant than yellow zinc it is a versatile finish that is best used indoors This finish should not be used in marine or high salt spray environments Grade 18 8 A general designation for the most common and popular stainless steel 300 Series referring to the 18 chromium and 8 nickel 9 16 18 UNF 2 1 8 quot OAL Steel Standard Coupling Nut Zinc Plated Finish 13 16 quot Width Across Flats MSC 64827132 Made in USA 250384 In Stock from rod couplings King Cobra Sucker Rod Guides More Coverage Two inches longer than Cobra guides King Cobra guides offer even greater EWV and increased contact with tubing resulting in a longer life of the rods and tubing These guides are designed for

A spin through rod centralizer consisting of a stator constructed of plastic or other appropriate material which is mounted on the rod coupling which provides the bearing surface for rotation of the coupling within the stator The stator which is free to rotate on the rod coupling and hence would move freely axially along the coupling is restrained from such axial movement by two 297 products Use a rod coupling nut to extend space or level a threaded rod or stud Coupler nuts also allow you to connect two threaded rods Reducer coupler nuts connect threaded fasteners with different diameters like a metric bolt and a standard rod For high moisture situations choose a coupler nut with a zinc chromate finish Steel Extra Long Coupling Nuts Known for their strength steel coupling nuts are available with a corrosion resistant finish Stainless Steel Extra Long Coupling Nuts Stainless steel coupling nuts have excellent corrosion resistance in most environments Round Coupling Nuts A smooth rounded body provides a finished look 3 8 in 16 TPI Zinc Rod Coupling Nuts Crown Bolt s rod coupling nuts are internally Crown Bolt s rod coupling nuts are internally threaded nuts in extended lengths Used with threaded rod the coupling nut joins 2 piece of threaded rod together from opposing ends for hanging various items either vertically or horizontally Generally hand tightened Available in various diameters and 2019 08 21 nbsp 0183 32 The 3 8 inch threaded rod coupling is galvanized steel and 1 1 8 inches long The coupling is used to join and extend threaded rods or bolts It can also be used as a barrel nut when the bolt s nut is recessed and it is easier to reach the nut with an extra thick long nut It can also be used to tighten 2 bolts together when you want to make a slightly loose connection
