About This Product

Hexagon socket head bolts are bolts developed to enable high-strength tightening. The development of this bolt led to rapid expansion and development of mechanical technology. This is because the high strength of hexagon socket head bolts allows us to manage stress, pressure, and vibrations applied to the joint. Today's technology requires increasingly high stresses, pressures, and speeds, making joints even more important, and requiring joint safety and reliability. Safe and reliable joints require fasteners that provide safe, reliable, high-strength fastening. At the same time, devices are required to be smaller and lighter in size for effective resource use, transportation, installation location, etc., and are also required to be safe and reliable. A single defect can destroy expensive equipment and stop the production line. Therefore, the reliability of fasteners used in joints with high safety and reliability must be comprehensive. High-strength tightening requires comprehensive reliability that combines fatigue strength and extra strength. Hexagon socket head bolts are the most comprehensive, easy-to-use, high-strength fasteners sought after by the market.
