An industrial fastener comprises a very wide range of items like nuts and bolts, washers, studs, nails etc. Nuts and bolts consist a major link in the family of industrial fasteners and are used by every industry. Bolt is a piece of metal rod, whose one end is upsettled and other end is threaded. Nut is the item which rolls on these threads. Nut and bolts are available in various shapes, designs and sizes. Nuts and bolts are used for fastening purpose in industries where the replacement of pieces and the parts is necessary. There are many industries producing these nuts and bolts of various sizes, but the demand too is increasing as well as the raw material for the products is easily and indigenously available. The main raw material is mild steel wire coil/rod of required diameter. The composition of materials controls the quality of the bolts and nuts. The recommended composition for nuts and bolts raw material is given as under

Carbon 0.22 to 0.23%
Phosphorus 0.40%
Manganese 0.39 to 0.60%
Sulphur 0.50%

Nuts and bolts are classified by two ways:

  • Their uses,
  • Shape of head.

In terms of use, nuts and bolts are of several type:

Larger dia bolts, machine bolts, stand bolts, joint bolts, foundation bolts and nuts etc. in terms of shape, bolt and nuts are classified by head shape like hexagonal head, square head, round head, pan head, truss head etc.

Market Potential

The demand of nuts and bolts is influenced by the following factors

  • Transportation industries, Railways, aircraft, wagon, bicycles, automobile, body builders, etc.
  • Electrical industries like manufacturing of transformer, electric motors, fans etc.
  • Building activities such as construction of bridges, fabrication of various steel structure etc.
  • Other heavy and light industries, steel and wooden furnitures, machine tools, agricultural machines and agricultural implements etc.

As various type of MS and HT nuts and bolts are used in above sectors, the market demand is directly proportionate to the development of these industrial segments.

Technical Aspects

Process of Manufacture

The raw material used for manufacture of bolt is M.S. Rounds. As some of the rounds available are rusty and not perfectly round and straight, it is necessary to make them round. The rounds are pickled in the acid tanks, washed and drawn in a drawing machine. The cleaned rod is fed into the cold heading machine. In the machine, one end of the rod is cut into the desired length with cutting stroke and simultaneously the head formation takes at other end. For the HT bolts, forging is done on hot forging press. The pins are then trimmed in the trimming machine. In quality bolts, the lower side of the head is also faced. Threading is done in the thread rolling machines.

While manufacturing nuts, the hexagonal rod of desired size is procured and the nuts are cut on the automatic nut-cutting machine. Cutted nuts blanks are drilled and tapped on the nut-tapping machine. Finally, these are deburred in the polishing barrel.
