Jinnox Bolt is one of the leading Bolt Manufacturers in India. A bolt is a kind of fastener that is used to secure or assemble materials—usually wood or metal—through holes that have already been drilled. It consists of a threaded shaft and a head, meant to function in concert with a nut to attach objects tightly. Bolts need a nut to keep the items together, in contrast to screws, which are driven into the material.
