Nuts and Bolts Manufacturing

Nuts and Bolts Manufacturing

As fundamental components for machines, buildings, and transportation, nuts and bolts are part of a thriving global market. Nuts and bolts are available in a wide range of types and sizes, including machine screws, lock nuts, stud bolts, hex nuts, and more. To start a nut and bolt business, it requires machinery such as cold forging machines, thread rolling machines, nut tapping machines, bolt-making die sets, and polishing machines, which can be procured from local or interstate equipment suppliers or through online marketplaces. The machinery cost for a small unit is Rs. 5 to 15 lakhs depending on capacity and automation level with the requirement of space is 500 to 1000 sft. Essential raw materials for manufacturing nuts and bolts include high-grade steel, stainless steel, or alloy steel rods, along with lubricants, plating chemicals, and suitable packaging supplies. Steel rods are cut to the required length, formed into bolts or nuts, and threaded for accuracy. The components are then heat-treated to enhance strength, coated for corrosion resistance, thoroughly quality-checked, weighed, packaged, and dispatched to the market. The products can be marketed through local hardware, furniture, welding shops, construction sites, and car factories.
