1. Fastener manufacturing
Bolts and nuts: Hexagonal bar steel is an ideal raw material for producing hexagonal bolts and nuts. Its hexagonal shape naturally fits the grip of tools such as wrenches, making it easy to tighten and disassemble. In mechanical assembly, from the assembly of automobile engines to the connection of various components of industrial machine tools, a large number of hexagonal bolts and nuts are used to achieve stable fastening effects. The correct size specifications and good strength of hexagonal bar steel ensure the reliable quality of these fasteners, which can withstand corresponding tensile, compressive, and shear forces.
Screws: Some larger hexagonal head screws with high strength requirements are also commonly made of hexagonal bar steel. For example, in construction machinery and mining machinery, equipment is subjected to high-intensity vibration and impact for a long time. Hexagonal head screws are made of hexagonal steel bars, which can more firmly connect key components, prevent loosening and detachment, and maintain the safety of equipment operation.
2. Shaft components
Small precision shaft: For some shafts with small dimensions and high precision requirements, such as transmission shafts in instruments and micro motor shafts, hexagonal bar steel can be converted into suitable shaft parts through precision machining. During the processing, based on its initial hexagonal shape, it is helpful for correct positioning and cutting, and the manufactured shaft performs well in rotation accuracy and stability, ensuring the sensitive operation of the instrument and equipment.
Multi angular transmission shaft: Some mechanical transmission systems require specially shaped transmission shafts to adapt. Hexagonal bar steel can be used to create hexagonal transmission shafts. Compared to ordinary circular transmission shafts, in specific transmission scenarios, it can better cooperate with transmission components with corresponding inner holes, reduce slip when transmitting torque, and improve transmission efficiency.
3. Tool manufacturing
Wrenches and sockets: Due to their hexagonal shape, hexagonal steel bars can be slightly processed and polished to produce various specifications of wrenches and sockets. These types of hand tools are widely used in mechanical maintenance and assembly sites. Workers can easily tighten hexagonal bolts and nuts with them, and tools made of hexagonal steel bars have good durability, can withstand large torques, and are not easily deformed or damaged.
Hexagonal socket screwdriver: When making hexagonal socket screwdrivers, hexagonal bar steel is the key material. By machining a suitable blade on one end of the bar, it can be used to disassemble and install hexagonal socket screws. It is commonly used in the assembly and disassembly of electronic devices and precision instruments, making it easy to operate and correctly adapted.
4. Mold accessories
Top pin and driver: In injection molds and die-casting molds, the top pin and driver are often produced using hexagonal steel bars. They are used to push molded plastic products and die-casting parts out of the mold cavity. The high strength and hardness of hexagonal bar steel ensure that the ejector pin and barrel will not bend or wear during frequent reciprocating motion, maintaining the normal operation of the mold and improving its service life.
Guide post and guide sleeve: The opening and closing process of the mold relies on the guide post and guide sleeve to guide and position. The guide post and guide sleeve made of hexagonal bar steel have good rigidity and high precision, ensuring smooth and correct opening and closing of the mold, avoiding mold damage or affecting product quality due to mold closing deviation.
