Finished Hex Nut Manufacturers – Top Quality Finished Hex Nut Suppliers in India!

  • Asiamet is a leading manufacturer, suppliers in India hex nuts are thicker and wider than finished hex nuts of the same size which makes them the strongest of comparably graded nuts. Their additional strength comes from increased thread engagement which is due to their thickness and greater resistance to dilation (expansion or stretching) because of their larger width. The heavy hex nuts increased size yields larger bearing surface and improved wrench ability. Hex is short for hexagon which means they have six sides. Lock washers may use with heavy hex nuts.
  • Threads are standard right hand and unified inch coarse series or unified inch fine. Left hand threaded heavy hex nuts are also available see Left hand nuts. Hex nut size refers to its nominal thread diameter. Typically sizes range from 1/4″ to about 3 1/2″. Size is specified in inches, usually fractional rather than decimal. Table 1 lists width across flats and across corners and thickness.
  • Width across flats, which is wrench size, ranges from about 1.53 to 2.00 times the nominal heavy hex nut size and height is 0.938 to 0.986 times the size. Nuts that are 7/16″ and smaller are double (top and bottom) chambered (beveled) larger sizes may be double chambered or have a washer face bearing (bottom) surface and a chartered top.
  • To ensure full thread engagement with the heavy hex nut, the bolt/screw should be long enough to allow at least two full threads to extend beyond the nut face after tightening. Conversely there should be two full threads exposed on the head side of the nut to make sure the nut can be properly tightened.

What is a Finished Hex Nut?

Hex nuts are six-sided, internally threaded fasteners, mated with bolts, studs, screws, and other externally threaded products. The addition of the hex nut ensures that the bolt etc. Hex nuts of standard thickness are called finished hex nuts. Hex bolts are bolts with a hexagonal head on one end, with no washer face on the bearing surface and a threaded shaft on the other end. The head of a heavy hex bolt is wider and thicker than that of a hex bolt. A heavy hex bolt goes with a heavy hex nut. The finished hex nut is perhaps the most commonly used nut in the world today. Found in structural, machinery and automotive applications, hex nuts and heavy hex nuts couple with bolts to create a tight, secure joint. The finished hex nut provides adequate strength for many different types of common applications.
