A fastener is a connective mechanism that mechanically joins or affixes two or more objects together. A bolt is an externally threaded fastener designed for insertion through holes in assembled parts, and is normally intended to be tightened or released by torquing a nut.
A nut is a type of hardware fastener with a threaded hole nuts and bolts are manufactured from alloy steels having high tensile strength and resistant to continuous wear and tear. Bolt is cylindrical piece of metal that fasten objects together. Bolts and nuts can be zinc or cadmium plating to resist corrosion. Bolt and nut are used to fasten together loose parts mainly in industries and workshops. Nut is device, which rolls on these threads. In nuts internal threading is done through the combination of nuts and bolts combination into appropriate sizes. Screw demonstrates their true merit in smooth movements, during assembly etc. Nuts and Bolts are available in various sizes and shapes. The kind of the classification of bolts and nuts may broadly be those made by the cold and hot process plant. Nuts are plain, square or hexagonal in shape with flat chambered, or washer crowned top. Bolts, nuts may be finished or unfinished, and may be regular or heavy type.
Fasteners mainly cover nuts, bolts, screws, studs and rivets and are segmented between MS (mild steel) and HT (high tensile) fasteners. These fasteners are used in engineering systems.The overall fasteners market is estimated at about Rs 28 bn. While the organized sector (HT fasteners) has a share of 65%, the balance of 35% is shared by unorganized sector and imports. In fact there isno assembly complete without fasteners. The automotive industry is the largest end-user of fasteners with the remaining demand coming from sectors like textile machinery, railway locomotives, construction, computer hardware and general engineering. Industrial fasteners, accounting for 40% of the total demand, are more oriented towards the retail markets. Original Equipment Manufacturer (OEM) segment is mainly dominated by organized players due to high intensity of capital and technology. As the sectors mentioned above use fasteners extensively and there is a vast replacement market spread across the country, hence the scope of venturing to this sector is highly promising. Thus, as an entrepreneur this project offers an exciting opportunity to you.
