A hex nut is a six-sided fastener commonly used in conjunction with bolts and screws to secure two or more components together. Its design allows for easy handling and tightening with standard wrenches or socket tools. Made from various materials such as steel, stainless steel, or nylon, hex nuts offer versatility and can withstand a range of environmental conditions. They are integral to numerous applications, from machinery and automotive assembly to construction and household projects. The hexagonal shape of the nut provides a stable grip and ensures a strong connection by distributing load evenly across the fastening surface.
