316 Stainless Steel Heavy Hex Nuts and SS 304 Hex Nut supplier and exporter in Mumbai

Jignesh Steel is one of the oldest & PED approved Hex Nuts manufacturers, which can be avail in various material grades according to the requirements of the customers. It is been manufactured by using high quality raw material with the guidance of our qualified technical team. Stainless Steel Hex Nuts is one of the most common nuts available and are used with anchors, bolts, screws, studs, threaded rods and on any other fastener that has machine screw threads. Hex is short form of hexagon, which means they have six sides. Hexagon Nut are also known as finished hex nuts, hex full nuts. Lock washers may use with hex nuts. Its size refers to its nominal thread diameter. Its typically, sizes range from 1/4" - 2 1/2" and its size are specified in inches. SS 304 Hex Nut has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is defined as Chromium-Nickel austenitic alloy nuts. It provides excellent corrosion resistance to a wide range of corrosive environments. It exhibit good machinability and have excellent weld-ability characteristics with or without the addition of filler metals.  18-8 SS Hex Nut generally refers to portions of the chemical composition, in this case, chromium and nickel. In raw form it is non-magnetic but can become magnetic as the microstructure is changed through cold-working. In A2-70 Hex Nut, “70” denotes the minimum tensile strength to be met by the hex nut. Therefore, it is an austenitic, acid proof stainless grade which has been cold worked to provide a minimum tensile strength of 700N/mm² (MPa). Heavy Hex Nuts is thicker and heavier in weight. Its part has a larger diameter across the flats and it also needs larger sockets and wrenches when being installed. The load strength is far higher compared to standard hex nut that means that it can bear more weight easily.
