Neelkamal Alloys LLP is one of the best companies in Chennai that manufacture, supply, stocks, and wholesales bolts. They have a huge selection of high-quality bolts that can be shipped anywhere in the world. We make bolts to order so that we can meet the unique needs of our customers in a wide range of fields. We sell high-tensile and stainless steel bolts, nuts, and fasteners that are used in big projects in Chennai’s power, wind, green energy, and infrastructure sectors. We are experts at making Hex bolts, nuts, stud bolts, and other hardware out of stainless steel. Bolts are very important in many fields because they make links strong and easy to put together. Our High Tensile Bolts are very strong, which makes them perfect for use in steel buildings and compression fittings.
A bolt is a fastener with external threads that can be tightened or loosened by turning it. It pairs with a nut that has internal threads. SS Bolts are often used to create a secure connection, as the nut’s clamping force combines with the bolt to hold parts firmly in place, preventing sideways movement. Many bolts feature a smooth section called the grip length, which strengthens the joint, similar to a pin. While this smooth section can sometimes distinguish bolts from screws, the real difference lies in how they are used.
