DIN 7985 Product Details
DIN7985 pan head is a pan-shaped screw head with a cross groove, which is widely used in various industries such as electromechanical equipment, electronic products and furniture. It has the following characteristics:
High-strength material: DIN7985 pan head is usually made of stainless steel or carbon steel, with high strength and hardness.
Beautiful and durable: The pan head has a beautiful appearance and is not easy to rust and corrode during use.
Easy to install: The pan head is used in conjunction with bolts, and the installation is simple and convenient.
High stability: The structural design of the pan head makes it have good anti-seismic and anti-loosening performance.
DIN 7985 The groove type of the head of cross pan head screw can be divided into H type and Z type.The cross pan head screw is generally used in the situation where greater stress is required. The larger pan head is more conducive to the fixation of the product to be fastened. At the same time, because the head is larger, it is more convenient to assemble. It is often used in the superposition and fixation of sheet metal parts. The plate head is large and the contact area between the fixed object and the plate head is large, which increases the axial tightness and is convenient for CNC punching of sheet metal parts.The cross pan head screw is widely used in the fastening of mechanical case, case or cover or parts of household appliances.
Are din7985 and GB818 the same?
DIN7985 and GB818 are not the same.
DIN7985 and GB818 represent the German industrial standard and the Chinese national standard, respectively, which are used to specify the specifications and technical requirements of different types of screws. DIN7985 is a German industrial standard, while GB818 is a Chinese national standard. The two are applicable to industrial standards and specifications in different countries and regions. This means that although they may involve similar product types (such as cross recessed pan head machine screws), the specific dimensions, tolerances, materials and other technical requirements may be different. Therefore, DIN7985 and GB818 are not equivalent standards, and manufacturers and users need to decide which standard to use based on specific project requirements and national/regional standards when choosing to use them.
In addition, the products provided by different suppliers may comply with different international or national standards, such as ASME B18.2.1 (American hexagonal bolts), JIS B1181 (Japanese standard single chamfer nuts), etc., which further illustrates that there are differences in standards and specifications for fasteners in different countries and regions. Therefore, for a specific project or product, it is very important to choose fasteners that meet local standards or customer requirements.
