fatus fasteners Germany fatus model fatus price

fatus fastener mechanical parts, cylindrical threaded fasteners used with nuts. A type of fastener consisting of a head and a shank (a cylinder with external threads), which must be used with a nut to securely connect two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, its characteristics include a wide variety of specifications, different performance and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people refer to this class of tight bolt fasteners that already have national standards as standard fasteners, or simply as standard parts. Also, these two parts can be separated, so bolted connections belong to detachable connections. Bolts play an important role in industry; as long as industry exists on Earth, the function of bolts will always be important.

fatus fastener shapes

Countersunk heads are generally used where a smooth surface without protrusions is required after connection, because the countersunk head can be screwed into the part. Round heads can also be screwed into the part. Square heads allow for greater tightening torque, but their dimensions are large. In addition, to meet the need for locking after installation, some have holes in the head or shank; these holes prevent the bolt from loosening due to vibration. Some bolts have a reduced-diameter unthreaded shank, known as waisted bolts. This type of bolt is beneficial for connections subject to variable loads. There are special high-strength bolts for steel structures, with larger heads and changed dimensions. Additionally, there are special-purpose types: T slot bolts are used most frequently in machine tool fixtures, having a special shape with both sides of the head cut off. Anchor bolts are used to connect and fix machines to the ground and come in many shapes. U bolts, as mentioned above. Etc.

fatus fastener performance

Advanced bolts are the foundation of high-end mechanical manufacturing, playing a pivotal role. On the surface, bolt output value accounts for only a few percent of the machinery industry. In essence, the added value they bring to key components and equipment is much higher. A type of fastener consisting of a head and a shank (a cylinder with external threads), which must be used with a nut to securely connect two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so bolted connections belong to detachable connections. Regarding products, mid-to-high-end products will accelerate the localization of quality R&D. The entire process from design, manufacturing, packaging, transportation, use to disposal must consider minimal waste, lowest emissions, high resource utilization, and minimal environmental impact, thereby coordinating and optimizing corporate and social benefits.

fatus fastener maintenance

Bolted connections require tight contact at the joint interface and sufficient coefficient of friction. When the design drawings do not specify requirements for the treatment of this interface, handle it according to the following regulations: Perform sandblasting or shot blasting on high-strength bolt interfaces to remove rust, oil, and other impurities from the surface. After treatment, protective measures should be taken on the friction surfaces of high-strength bolt connections to prevent contamination by dirt and oil. It is strictly prohibited to make any marks on the friction surfaces of high-strength bolt connections. Special care must be taken to prevent contamination of the connection surfaces during storage in the factory, transportation, and custody at the installation site. The installation unit must pay special attention to protecting the cleanliness of the connection plates and base material connection surfaces of high-strength bolts and the characteristics of the friction surfaces. Arbitrary grinding of the connection plate and base material connection surfaces with a grinder is not allowed.
