Heavy Hex Jam Nuts

We are leading Manufacturers & Supplier of Heavy hex jam nuts in Nickel 200/201, Monel 400, Inconel 600/625, Incoloy 800 ,800H & 800HT, Hastelloy C22/Hastelloy C276, Alloy 904 L/Alloy 20, Ti Grade 1/2/3/4/5/7. These are thinner than a standard heavy hex nut but have the same dimension across the flats and corners. Heavy hex jam nuts have two common applications. A heavy hex jam nut can be threaded onto a bolt and run tight against the standard heavy hex nut which will lock the nut in place and prevent it from backing off. Heavy hex jam nuts are sometimes used for leveling purposes as well. Since hot-dip galvanizing typically adds 2.2 to 5 mils of thickness to the threaded portion of a fastener, galvanized heavy hex jam nuts are tapped oversize to compensate for the corrosion resistant coating on the bolts.
