Hex bolts are typically a steel or stainless-steel threaded bolt distinguished by their head's six-sided hexagonal form. Hex bolts have high tensile characteristics and hold well under tension. They can be completely or partly threaded (having a visible shaft across their body). Hexagonal bolts are adjustable and versatile fasteners that are useful in various settings and they are able to fasten components made from metal, wood, and several other materials. Hexagonal bolts are a popular type of fastener as a result of these traits and they are particularly used in the construction and industrial industries.
Manufacturers most frequently use a process called cold-forming to create hex bolts. This process requires a machine that typically has a set of three or more dies that sequentially form a metal blank into a desired final shape and dimensions. For cold forming to begin, big steel wire rods are uncoiled and trimmed to length. The metal is left cold and formed into the proper shape using specialized tools. In essence, the steel is shaped while still being left at room temperature by being pushed through a sequence of dies under intense pressure. Cold forged special for small size ，such us from M3-M30
A hot-forged bolt is manufactured by heating a steel rod to a high, malleable temperature and then using a forging press or upsetter to form the bolt's head.This process aligns the metal's grain structure, increasing the bolt's strength, fatigue resistance, and overall durability, making it ideal for large-diameter applications, long lengths, unique shapes, and critical industries where reliability is paramount.Gennerally the size is big size , fromM 36 -M100.
