GB5782 and GB5783 are hexagonal bolts defined in Chinese national standards, and they are mainly used for connecting and fixing various mechanical parts. The main difference between these two types of bolts lies in their threaded parts: GB5782 is a half-threaded bolt, i.e., one end of the bolt is only partially threaded; while GB5783 is a full-threaded bolt, i.e., both ends of the bolt are fully threaded. These are the same as the German standard DIN931 DIN933.
They are available in a variety of performance grades, including 4.8, 8.8, 10.9, 12.9, etc. to meet different strength and corrosion resistance requirements.
Material-wise, these bolts can be manufactured from a wide range of materials such as carbon steel, stainless steel, etc. to meet the needs of different working environments.
High strength: These bolts have high tensile and yield strength and can withstand large loads.
Corrosion Resistance: High quality materials and surface treatment process make these bolts have good corrosion resistance, suitable for various harsh environments.
Easy to install: the hexagonal head design makes these bolts easy to use wrenches and other tools for fastening and dismantling.
Standardized: following the unified national or industrial standards, easy to purchase and interchangeable use.
Scope of
application
GB5782, GB5783, DIN931 and DIN933 bolts are widely used in the following scenarios due to their excellent performance and wide range of applications:
Mechanical equipment: In mechanical equipment, these bolts are used to connect and fix various key components to ensure the stable operation of the equipment.
Construction: In steel structures, bridges and other construction projects, these bolts are used to connect heavy components and provide strong support.
Automotive industry: In the process of automobile manufacturing, these bolts are widely used in the connection and fixation of body structures, engines, chassis and other parts.
Other industrial sectors: including aerospace, petrochemicals, rail transportation, etc. These sectors require extremely high performance and quality of fasteners, and hence these bolts are also widely used.
