This is a special Grade 5 coupling nut that is used together with a special mold bolt and square washer pictured below. It measures 3/4-10 by 1-1/2 inches in length, and can be supplied with plain and light oil finish or hot dip galvanized finish as pictured here. Together with the other two components, this coupling nut is supplied on a blanket as-released order basis.
We supply a number of version of this special pin made using Inconel alloy C-276 material in the USA. The part is stocked and released as needed to our long time customer. The inconel materal is hot rolled, pickled, and annealed - the final pins shown here measure 1/16 X .850".
